Accreditation self-declared
Hong Kong government metrology laboratory, custodian of the reference standards for physical measurement, that runs proficiency testing programmes for local and overseas calibration and testing laboratories in electrical, time, temperature and humidity, acoustics, photometry, mass and dimensional measurement.
Electricity and magnetism PT (digital multimeter, multifunction calibrator, power meter, oscilloscope)
Time and frequency PT (stop watch)
Temperature and humidity PT (PRT, thermocouple, liquid-in-glass and digital thermometers, RH instruments)
Acoustics PT (sound calibrator, sound level meter, audiometer)
Photometry PT (illuminance meter)
Mass and related quantities PT (standard weights, pipettes, electronic balances)
Dimension PT (calliper, engineer's steel rule)
