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.
