Calibration Services in Chennai - Nagman Calibrators






Nagman calibration LLC a unit of Nagman Instruments pvt ltd is the first calibration laboratory in India to be accredited with ISO/IEC 17025 standards and NABL empaneled auditors & quality control Inspectors with ISO9001/14001for total calibration solutions. 

Nagman calibration labs in Chennai & Mumbai covers all scientific parameters like Thermo electric, Mechanical (Pressure, vacuum, flow, temperature, level, mass, dimension and volume) & fluid flow (Process flow meter & water calibration meter). The centers are also equipped with sophisticated calibration equipment’s and computerized automated calibration reporting of primary/secondary transfers of data.  



Dead Weight Testers Calibration
Nagman dead weight tester comes in both pneumatic and hydraulic types, for cost effective way of measuring pressures in industrial scale. With good accuracy range from +- 0.015 to +-0.15 and a range of up to 700 & 1200 bar in models, the gauge calibration techniques in Nagman pressure calibrators produce finite and expected results in Pressure measurements.

Basically operating in the principle of P=F/A. The applied pressure to the fluid through piston produces a change in pressure to the dead weight in the instrument, which is noted as the gauge pressure or noted pressure reading.  

Mostly hydraulic dead weight testers are used in many industrial applications, which operate on the principles of fluid motion pressure exerted from Instruments. Nagman’s H series dead weight testers namely 600, 900, 900 N, 3000, 6000 can be used for wide range applications based on Industrial conditions for   Instrumentation calibrations. 

The 3000 & 6000 series dead weight testers have the advantage of being portable. The P 8000/8600 dead weight tester’s series from Nagman operate on the pneumatic principle which is air pressure with fine accuracy from +-0.05 to +- 0.025% and maximum range of 35 bars. Finally the GCL-HP & GCH-HP series comparison dead weight testers have a wide range from 0 to 250 bar to 1400 bar with low maintenance cost in handling. These dead weighttesters are mainly used to check the pressure in measuring devices.

How to Calibrate Temperature Sensors?

Temperature sensors are critical components in various industries, ensuring precise measurements for optimal performance. Calibrating these sensors is essential to maintain accuracy, and three primary methods are employed for this purpose. Each method offers distinct advantages and limitations, affecting the reliability of temperature readings. This article will delve deeper into these methods and analyse their pros and cons to understand temperature sensor calibration comprehensively. Three Major Strategies for Calibrating Temperature Sensors Calibrating with a Temperature Simulator Calibrating temperature sensors using a temperature simulator remains a rapid and efficient approach. A temperature simulator accepts an input temperature and generates corresponding electrical signals, such as voltage or resistance, based on established national standards. Let's explore further the benefits and drawbacks of this method. Pros Speed and Efficiency: The use of a temperature simulator ...

The Fundamentals of Pressure Calibration

Pressure calibration is the process of verifying and adjusting the accuracy of pressure measurement devices, like pressure gauges, transmitters, and sensors. This ensures that these instruments provide accurate readings, which is critical in industries like oil and gas, pharmaceuticals, aerospace, and manufacturing. Proper calibration helps maintain safety, ensure product quality, and improve overall system performance. Here are the essentials of pressure calibration: 1. Understanding Pressure Calibration Pressure calibration is performed by comparing the readings from a device under test (DUT) with a reference standard of known accuracy. Calibration corrects for any deviations between the instrument’s measurements and the actual pressure, bringing the device within acceptable accuracy limits. Calibrations are typically performed at intervals, as part of routine maintenance, or whenever accuracy concerns arise. 2. Types of Pressure Gauge Pressure : Measures pressure relative to ambien...

What is a Dead Weight Tester & How it works?

Every business that uses pressure instruments to monitor fluid and gas pressures and flow rates relies on accurately calibrating today's high-tech pressure measurement instrument s. Pressure is a complex measurement discipline. And to have precise measurements, pressure gauge calibration is necessary. That's where pressure calibrators come in. There needs to be a calibration kit for pressure gauges that is universally suitable for all users' needs. Pressure gauge calibration standards diverge substantially based on their uses and the setting in which they are utilized. That’s why there are different types of pressure calibrators for different scenarios. For example, a dead weight tester, multifunction calibrator, or measuring gauge with a predefined accuracy can examine the accuracy of transmitters, sensors, transducers & pressure gauges. Today, we will review what these dead-weight testers are and how they work. Deadweight Testers - What are They? The DWT -...
