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 our most frequently requested service for pharmaceutical manufacturing units in Bommasandra, Jigani, and Peenya, as well as biotech R&D labs across Electronic City and Whitefield.

• Fixed Point Calibration (Triple Point of Water): For advanced research laboratories, semiconductor fabs, and aerospace testing facilities near ISRO centers, HAL, NAL, and academic research institutes in Bangalore, we offer Fixed Point Calibration at the Triple Point of Water (0.01°C).It is particularly valuable for organizations acting as secondary reference labs within biotech, aerospace, and national research ecosystems.

• Electrical Simulation:Many automated production lines and Building Management Systems (BMS) across ITPL, Whitefield, and Peenya Industrial Area depend on precise electrical interpretation of RTD signals.
  Using high-precision multifunction process calibrators, we simulate RTD PT-100 resistance values (Ohms) to verify the accuracy of indicators, temperature transmitters, recorders, PLC inputs, and SCADA systems.

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 Bangalore laboratory is equipped with ultra-stable, stirred liquid baths that provide the extreme thermal uniformity required for precision validation. Every calibration performed for our clients in the KIADB Industrial Areas or Jigani results in an NABL-accredited certificate featuring a detailed Uncertainty of Measurement (MU) budget. This level of detail is essential for meeting the quality standards of the USFDA, EMA, and the Indian Space Research Organisation (ISRO).

Industry Segments We Serve

Biotechnology and Pharmaceutical Research

Bangalore is the "Biotech Capital of India," home to major clusters in Bommasandra and Jigani. In these facilities, precision is a life-critical requirement. Glass thermometers are utilized as primary check-standards for stability chambers, bioreactor jackets, and incubation baths. Because glass is immune to the electromagnetic interference (EMI) that can sometimes plague electronic sensors in a crowded lab environment, they provide a reliable, "unplugged" verification of critical setpoints. Our calibration ensures that your "As-Found" and "As-Left" data satisfies the most stringent WHO-GMP and 21 CFR Part 11 audits, protecting the integrity of life-saving drug research.

Semiconductor and Electronics Manufacturing

For the high-tech fabrication units in Whitefield and ITPL, maintaining specific ambient temperatures in cleanrooms is essential. While automated systems control the environment, glass thermometers are often used by quality teams as a manual "master" to verify the accuracy of integrated Building Management System (BMS) sensors. Our calibration ensures that these manual checks are accurate to within a fraction of a degree, preventing humidity spikes or thermal fluctuations that could ruin sensitive silicon wafers.

Food, Beverage and FMCG Production

From the massive dairy processing units in Marathahalli to the food manufacturing hubs in Yeshwanthpur, consumer safety is paramount. Glass thermometers are the standard tool for routine temperature verification during pasteurization and UHT processes. If a digital display fails or drifts, the glass thermometer is the reliable backup. We help these industries maintain FSSAI and ISO 22000 compliance by providing traceable accuracy that ensures all pathogens are eliminated during the heating cycles.

Industrial Use Cases

Food and Beverage Production

From the dairy units in the outskirts to the food processing giants, 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 Peenya Industrial Area, glass thermometers are used in oil baths for the heat treatment of precision gears and bearings. Maintaining the exact temperature of the quenching or tempering bath is vital for achieving the correct Rockwell hardness of the metal. Vega’s NABL-certified calibration provides the documented proof of accuracy required for IATF 16949 audits, ensuring that Bangalore-made components meet the global standards of the automotive and heavy machinery industries.

Cold Chain Verification for Seafood & Perishable Food Handling in Bangalore

In Bangalore’s food processing and export ecosystem, glass thermometers play a vital role in maintaining cold chain integrity during the handling of seafood and other perishable products. These thermometers are routinely used to verify temperatures in ice slurry tanks, cold storage rooms, blast freezers, and pre-dispatch inspection areas at processing units and logistics hubs around Yeshwanthpur, Nelamangala, and the Kempegowda International Airport cargo zone. Accurate temperature monitoring ensures compliance with HACCP, FSSAI, and Codex Alimentarius food safety standards, preventing microbial growth and product quality degradation. Despite Bangalore’s moderate climate, even brief temperature deviations during storage or air-cargo staging can impact shelf life. NABL-calibrated glass thermometers provide reliable, traceable verification, safeguarding export quality and ensuring acceptance at domestic and international markets.

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

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: Can Vega calibrate the "Eco-Friendly" non-mercury thermometers used in our green-certified lab in Electronic City?

A:Yes, we specialize in spirit-filled and organic-liquid-filled thermometers. It is important to note that these liquids have different wetting properties than mercury and can sometimes "cling" to the glass, leading to drainage errors. Our technicians account for this "drainage time" during calibration to ensure the most accurate reading possible.

Q: Is it true that glass thermometers are more reliable than digital probes for long-term storage?

A: In many ways, yes. Glass thermometers do not have batteries to die, circuits to corrode, or software to glitch. This makes them the ideal "Check Standard" for your facility. By periodically checking your digital sensors against a calibrated glass thermometer, you can identify electronic drift before it causes a major process deviation.

Q: What is the significance of the "ASTM" or "IP" marking on my thermometer?

A: These markings indicate that the thermometer was manufactured to strict international dimensions and accuracy specifications for a specific test (like flash point or viscosity). When we calibrate an ASTM thermometer for a client in Peenya, we verify not just its accuracy, but its conformity to those specific international standards.

Q: How often should I send my reference thermometers from Jigani for NABL calibration?

A: For reference-grade thermometers used to check other instruments, an annual (12-month) cycle is the industry standard. However, for thermometers used daily in high-temperature processes 150°, we recommend a 6-month calibration to monitor for glass fatigue and zero-point drift.
