To maintain technical excellence , we employ methodologies that account for the unique stress factors of the region:Thermal Comparison Calibration

• Thermal Comparison Calibration: Thermal Comparison Calibration is one of our most frequently requested services for pharmaceutical manufacturing units, cold storage facilities, and heavy engineering process plants across Delhi, Noida, Greater Noida, Faridabad, and Gurugram industrial corridors. RTD PT-100 sensors are compared against a Master SPRT in a stabilized medium to ensure accurate As-Found performance under real process conditions.

• Fixed Point Calibration (Triple Point of Water): For advanced research laboratories, precision testing facilities, and quality reference labs supporting industries in and around Delhi and the NCR industrial belt, we offer Fixed Point Calibration at the Triple Point of Water (0.01°C). This method is ideal for organizations maintaining secondary reference standards for pharmaceutical, chemical, and high-accuracy temperature validation.

• Electrical Simulation: Many automated production lines, cold warehouses, and Building Management Systems (BMS) operating across Delhi’s industrial, logistics, and institutional hubs rely on accurate electrical interpretation of RTD signals. Using high-precision multifunction process calibrators, we simulate RTD PT-100 resistance values to verify indicators, transmitters, PLC inputs, recorders, and SCADA systems, ensuring complete temperature control loop accuracy.

Types of NABL Temperature Calibration Services

Our service portfolio is designed to cover the entire lifecycle. We offer :

At Vega, we treat glass thermometer calibration as a refined metrological science. We move beyond simple verification by performing a full characterization of the instrument’s behavior across its scale. We account for the physical expansion of the thermometric liquid and the long-term contraction of the glass bulb—a phenomenon known as "bulb aging" that can lead to significant measurement errors if left unmonitored.

Our Delhi laboratory uses ultra-stable stirred liquid baths that provide a temperature uniformity of 0.01°, essential for calibrating thermometers used in high-precision environments like Bawana and Narela. Every calibration performed for our clients in the Delhi-NCR region results in an NABL certificate featuring a detailed Uncertainty of Measurement (MU) budget. This documentation is critical for maintaining compliance with SFDA, BIS, and international quality benchmarks.

Industry Segments We Serve

Pharmaceutical & Life Sciences

Across regulated pharmaceutical manufacturing zones and clinical research facilities, high-precision glass thermometers are used as primary reference standards for monitoring stability chambers, incubators, water baths, and cold storage units. In GMP-controlled environments, where electronic sensors may suffer from drift or EMI interference, Liquid-in-Glass thermometers provide a stable, power-independent benchmark trusted by auditors. Accurate temperature control is critical for ensuring drug stability, potency, and patient safety. Vega’s NABL-accredited calibration ensures these thermometers deliver traceable accuracy, supporting compliance with WHO-GMP, USFDA, and SFDA requirements during routine inspections and validation audits.

Chemical & Laboratory Research

In analytical laboratories, R&D centers, and chemical testing facilities, glass thermometers are widely used for monitoring reaction temperatures, distillation setups, and controlled synthesis processes. Their resistance to corrosive chemical vapors and immunity to electromagnetic interference make them ideal for laboratory environments where electronic probes may degrade or fail. Precision temperature measurement is essential for repeatability, reaction yield, and data integrity. Vega’s NABL-certified calibration ensures these reference thermometers maintain accuracy across their operating range, providing defensible measurement data that supports ISO 17025 compliance, method validation, and globally accepted laboratory results.

Food, Beverage & FMCG

Food processing plants, beverage bottling units, and FMCG manufacturing facilities across Delhi and the NCR region rely on glass thermometers for manual temperature verification during pasteurization, sterilization, cooling, and cold storage processes. These instruments perform reliably in high-humidity, steam-rich production areas where electronic sensors may be affected by moisture ingress or frequent washdowns. Accurate temperature control is critical for neutralizing microbial risks and ensuring product safety, shelf life, and regulatory compliance. Vega’s NABL-accredited calibration provides traceable accuracy for these thermometers, helping manufacturers meet FSSAI, ISO 22000, and HACCP requirements while maintaining consistent quality across high-volume production cycles.

Industrial Use Cases

Food and Beverage Production

From dairy operations in the surrounding regions to organized food processing facilities across Delhi, NCR, Ghaziabad, Faridabad, and Noida, manual temperature checks are a safety mandate. Glass thermometers are rugged enough to withstand the steam and high-moisture environments typical of pasteurization and sterilization tunnels. We help these industries maintain ISO 22000 compliance by providing traceable accuracy that ensures biological risks are neutralized during production.

Precision Mechanical Engineering

In the Delhi NCR industrial clusters, including Faridabad, Noida, Gurugram, and Bawana, glass thermometers are used in oil baths for the heat treatment of precision components such as gears and bearings. Maintaining the exact temperature of quenching or tempering baths is critical for achieving the correct Rockwell hardness. Vega’s NABL-certified calibration provides documented proof of accuracy required for IATF 16949 audits, ensuring NCR-manufactured components meet global automotive and machinery standards.

Chemical and Hazardous Material Storage

Chemical storage facilities and hazardous material warehouses across Delhi and the NCR region, including Bawana, Narela, Okhla, Ghaziabad, Faridabad, and Noida, use glass thermometers to monitor the ambient temperature of volatile chemical storage areas. In environments where electronic probes may pose a spark risk or suffer corrosion from aggressive fumes, the Liquid-in-Glass (LIG) thermometer remains the safest and most reliable tool. Vega’s NABL-accredited calibration ensures these manual safety checks are accurate to within a fraction of a degree, mitigating fire and explosion risks while supporting compliance with PESO, CPCB, and Indian hazardous material storage safety regulations.

Compliance & Audit Requirements

Whether it is an NABL assessment or a customer-led quality audit, our documentation is your strongest asset.

• Metrological Traceability: A clear, documented link to National Standards (NPL).

• Uncertainty Budget: A technical breakdown of measurement risks, a core requirement of ISO/IEC 17025:2017.

• Statement of Conformity: Clear indication if the sensor meets Class A, Class B, or custom tolerance limits.

• Digital Tracking: Automated certificate tracking to ensure you never miss a recalibration date.

Why Vega is Your Trusted Calibration Partner in Delhi

Vega Calibration is more than a service provider; we are your local partner with a national perspective.

• Emergent Stem Correction: If a total immersion thermometer is used incorrectly with only the bulb submerged, it results in a significant "Emergent Stem" error. Our technicians monitor the ambient temperature of the emergent column during calibration to apply the necessary corrections.

• Ice Point Verification (0°C): Over years of use, the glass bulb can undergo "Zero-Shift" as the glass material relaxes. By identifying this shift, we provide you with a precise correction factor that must be applied to all subsequent readings.

• Column Reunion: We utilize specialized cooling and heating techniques to reunite separated liquid columns, a frequent issue encountered when thermometers are handled in busy workshops or transported through the high-vibration environment of port logistics.

Frequently Asked Questions (FAQs)

Q: Why does the liquid column in my thermometer break after transport to my Gurgaon facility?

A: This is usually due to mechanical shock or vibration during transit. While it looks like a defect, it can often be fixed. At our Delhi lab, we reunite the column using deep-freeze or heating methods before performing the NABL calibration to ensure it is in perfect working order.

Q: Can Vega calibrate "Mercury-Free" spirit thermometers for our ISO 14001 initiatives?

A: Yes. We specialize in organic-liquid-filled thermometers. Note that these are more prone to "drainage errors" (liquid sticking to the glass), which our technicians account for during the calibration process.

Q: How do I know if I should be using a "Total Immersion" or "Partial Immersion" thermometer?

A: Look for a line etched around the stem. If there is a line (usually with a number like "76mm"), it is a partial immersion thermometer. If no line exists, it is likely total immersion. Using one in place of the other without the correct correction factor can lead to an error of several degrees.

Q: Is it true that glass thermometers "age" over time?

A: Yes. The glass bulb can contract slightly over years of use, causing the reading to slowly rise. This is why we perform an Ice Point check (0°) during every calibration to identify this "Zero-Shift."
