Process calibrators are precision instruments used to test, verify, and adjust the accuracy of measurement devices such as temperature sensors, pressure gauges, transmitters, and electrical signal instruments. They make sure that industrial readings are correct and compliant with standards. Without calibration, even a minor sensor drift can cause product defects, energy loss, safety failures, and production downtime.
Nagman’s Process Calibrators are engineered for fast, accurate, and field-ready calibration, making them a trusted choice for technicians and engineers across various industries.
Why Calibration is Essential for Industry
Every industrial process relies on accurate data. Temperature readings affect product quality, pressure determines equipment safety, and electrical signals control automated systems. When these values are wrong, operations are at risk.
Calibration helps industries:
Maintain accurate measurement
Prevent equipment breakdown and failures
Ensure safety, health, and regulatory compliance
Increase energy efficiency and reduce waste
Maintain product quality and consistency
A calibrated instrument equals a reliable process. That is why calibration is built into ISO standards and industry audits—especially in pharmaceuticals, food processing, HVAC, and petrochemicals.
Nagman—A Pioneer in Calibration Solutions
Nagman began in 1972 as a manufacturer of RTD/TC temperature sensors. Over time, they became a pioneer of portable calibrators and calibration workstations in India. Today, Nagman is:
ISO 9001:2015-certified
Trusted in 85+ countries
Known for rugged, durable instruments built for factories
Supported by a network of regional offices and distributors
A provider of calibration services as well as instruments
Nagman also operates an NABL-accredited calibration laboratory (ISO/IEC 17025) in Chennai and Mumbai, offering calibration of thermal, electro-technical, dimensional, mechanical, and fluid flow parameters—including on-site calibration support. This makes Nagman a complete calibration ecosystem, not just an equipment manufacturer.
What Do Nagman’s Process Calibrators Do?
Nagman’s Process Calibrators handle multiple functions in one device. They can:
| Function | Examples |
|---|---|
| Calibrate temperature instruments | RTD probes, thermocouples, transmitters |
| Verify pressure accuracy | Pressure indicators, gauges, pressure transmitters |
| Generate and measure electrical signals | mA, mV, voltage, frequency, loop testing |
| Support automation system diagnostics | PLC signal checks, sensor monitoring |
Unlike basic testing tools, process calibrators are designed to simulate and measure, meaning they can test whether a device reads correctly and adjust it when needed.
Where Are They Used? – Industries That Depend on Them
Process calibrators play an important role in every plant where data monitoring is critical:
| Industry | Use Case |
|---|---|
| HVAC & Refrigeration | Calibration of temperature & pressure sensors that control air quality, cooling performance, and energy efficiency |
| Pharma & Biotechnology | Ensuring cleanroom and sterilization temperature measurement accuracy |
| Petrochemical & Refinery | Accurate transmitter calibration is vital for safety in high-risk zones |
| Food & Beverage | Temperature-controlled cooking & cold chain monitoring |
| Power Plants | Monitoring boilers, turbines, transformers, control panels |
| Water & Utility | Flow & pressure-based automation |
In HVAC alone, Nagman Process Calibrators help technicians complete routine maintenance and troubleshooting faster, thanks to simple controls, intuitive menus, and software capabilities for data logging and report generation.
