As an ISO/IEC 17025:2017 accredited laboratory, we offer distinct types of thermal calibration services that cater to the rigorous demands of auditors and quality assurance protocols:

• Laboratory (In-House) Calibration: Recommended for primary standards and high-precision PT-100 sensors used as master instruments. This is performed at our controlled environment facility where we utilize fixed-point cells or highly stable liquid baths to achieve the lowest Calibration and Measurement Capability (CMC).

• On-Site (In-Situ) Calibration: To minimize downtime for our clients in Panchkula, Zirakpur, and Derabassi, we bring our NABL-accredited mobile calibration standards directly to your plant. This is vital for process sensors that are difficult to remove, such as those installed in large autoclaves or fermenters.

• Comparison Method Calibration: The most common service for industrial PT-100s, where your Unit Under Test (UUT) is compared against a Standard Platinum Resistance Thermometer (SPRT) in a stable heat source (Dry Block or Oil Bath) across a range of -80°C to 660°C.

• System Calibration (Loop Calibration): We calibrate the entire measurement loop—from the PT-100 sensor to the temperature controller or PLC display—ensuring the final reading you see on your panel in Ludhiana or Ambala is accurate and reliable.

Industry Segments We Serve

Pharmaceutical & Biotechnology Sector

The pharmaceutical industry is the backbone of the region, especially in the Baddi and Paonta Sahib industrial belts near Chandigarh. This sector relies heavily on thermal precision to maintain the efficacy of drugs and vaccines. An uncalibrated PT-100 sensor in a stability chamber or a lyophilizer can lead to catastrophic batch failures or regulatory warning letters. For these companies, calibration is not just a maintenance task; it is a critical quality attribute. The reliance on RTD sensors for monitoring critical process parameters (CPPs) means that even a deviation of 0.1°C can impact the chemical reaction rates or the sterility assurance levels of the final product. Regular calibration ensures that these manufacturers meet the stringent "GxP" guidelines enforced by global regulators.

Food Processing & Cold Chain Logistics

With Punjab and Haryana being the breadbasket of India, the food processing industry in Kharar, Rajpura, and Sirhind is massive. This segment utilizes RTD PT-100 sensors to monitor pasteurization temperatures, fermentation tanks, and cold storage facilities. In the dairy industry, for instance, pasteurization requires holding milk at a specific temperature for a precise time; if the sensor reads incorrectly, the milk may either spoil or retain harmful bacteria. Similarly, in the cold chain logistics hubs around Zirakpur, maintaining the integrity of frozen foods during transport requires accurate temperature logging. Calibration ensures that these sensors provide truthful data, preventing food spoilage and ensuring compliance with FSSAI safety standards.

Automotive & Ancillary Engineering

The engineering hubs in Mohali and nearby Parwanoo accommodate numerous automotive component manufacturers who require precise thermal treatment of metals. Heat treatment processes like annealing, hardening, and tempering rely on furnace temperatures controlled by industrial PT-100 sensors. If a sensor drifts, the metal may not achieve the desired hardness or tensile strength, leading to component failure in vehicles. Furthermore, in engine testing laboratories, RTDs measure coolant, oil, and exhaust temperatures. Accurate calibration of these sensors is essential for R&D validation and ensuring that the final automotive parts meet the strict durability and safety specifications required by original equipment manufacturers (OEMs).

Healthcare & Medical Research Institutes

Chandigarh is home to premier medical institutes and hospitals that utilize varying thermal equipment. From blood banks storing life-saving plasma to microbiology labs incubating cultures, temperature accuracy is non-negotiable. Hospitals in Chandigarh Sector 32 and Sector 16 use autoclaves to sterilize surgical instruments. These autoclaves operate based on temperature feedback from PT-100 sensors. If the sensor is reading high, the autoclave might not reach the actual sterilization temperature, putting patient safety at immense risk of infection. Therefore, biomedical engineering departments rely on accredited calibration services to validate that their equipment is performing correctly and safely.

Industrial Use Cases

Validation of Steam Sterilization (Autoclaves)

In pharmaceutical manufacturing plants in Solan and Nalagarh, autoclaves are used to sterilize equipment and vials. The use case involves the critical mapping of the autoclave chamber using multiple PT-100 sensors to ensure uniform heat distribution. A specific use case is the "Load Pattern Validation," where sensors are placed inside the actual product load. If the controlling PT-100 sensor of the autoclave is out of calibration, it might indicate that the cycle has reached 121°C when it is actually at 119°C, failing to kill hardy spores. Regular calibration of these sensors ensures that the lethality (F0 value) calculated is accurate, guaranteeing sterility and patient safety.

Temperature Mapping of Warehouses & Cold Rooms

Logistics companies in Dappar and Lalru utilize massive warehouses to store temperature-sensitive goods. The use case here is the deployment of calibrated PT-100 sensors or data loggers to map the thermal profile of the entire storage area. This helps in identifying "Hot Spots" or "Cold Spots" where the HVAC system might be ineffective. For example, a pharmaceutical warehouse must keep products between 15°C and 25°C. Calibration ensures that the sensors near the roof (which are generally hotter) and near the floor (generally cooler) are reading accurately. This data is crucial for auditors to prove that the drug was stored within its labeled conditions throughout its shelf life.

Process Control in Chemical Reactors

Chemical plants in Ropar and Nangal utilize jacketed reactors where exothermic or endothermic reactions take place. The use case involves using PT-100 sensors to measure the internal temperature of the reactor to control the flow of cooling or heating fluids in the jacket. If a reaction requires a precise temperature of 60°C to maximize yield and minimize by-products, a calibrated sensor is the only way to achieve this. A drift in the sensor could cause the reaction to "run away" (overheat) leading to safety hazards, or "stall" (cool down) leading to poor product yield. Precise calibration allows for tight PID control of these hazardous processes.

Environmental Chamber Testing for Product Durability

R&D centers in Manimajra and Panchkula use environmental test chambers to subject products (like electronics or plastic components) to extreme temperature cycling (e.g., -40°C to +85°C). The use case is verifying that the product can withstand these conditions without failure. The chamber’s controller relies on a PT-100 sensor. If this sensor is inaccurate, the test results are void. For instance, if a test requires -40°C but the chamber is actually at -35°C due to sensor error, the product hasn't been tested to its specified limit. Calibration ensures that the stress tests performed on the products are valid and that the product specifications are genuinely met.

Compliance & Audit Requirements

Vega Calibrations ensures your facility is "Audit-Ready" for global standards:

• ISO/IEC 17025:2017: The primary standard for calibration labs. Auditors look for "Metrological Traceability" to SI units. Our certificates provide the uncertainty of measurement, which is mandatory for your risk assessment.

• 21 CFR Part 11 & cGMP (USFDA): For pharma clients in Baddi, electronic records of calibration are vital. Auditors verify that the calibration frequency (interval) is scientifically justified and that "As-Found" and "As-Left" data is recorded to detect any instrument drift that could have impacted past batches.

• ISO 9001:2015: Requires that measuring equipment be calibrated or verified at specified intervals against measurement standards traceable to international or national measurement standards.

• HACCP (Food Safety): Requires critical control points (CCPs) like temperature to be monitored by calibrated devices. Auditors in Ludhiana's food parks will demand valid calibration tags on all pasteurizers and cold storage sensors.
