Although some parameters are yet to be covered under NABL accreditation, NPKLAB fulfils all requirements of traceability and technical competency for its unique facility for Flow calibration :

Parameter & Instruments / Equipment	Range of calibration
Liquid Flow measuring instruments	0.05 to 25 ml/min
Gas flow measuring instruments using dry air, Nitrogen, Hydrogen as medium gas	0.5 to 2000 ml/min
Anemometer / Air velocity meter	0.2 to 40 m/s
Wet gas flow meter	1000 ml

NPKLAB considers itself as a part of scientific community dedicated to standardisation for the benefit of the industry. It is the responsibility of every community member to establish the traceability chain where the facilities are lacking. NPKLAB has developed its own methods by referring to all available technical content, published papers, technical bulletins of leading manufacturers in instrumentation which has been validated & endorsed time to time by our valued customers.

NPKLAB specialises in calibrating non-standard instruments in various segments :
