Environmental Monitors Calibration

Results of environmental parameters monitoring compaigns could lead to financial penalties or fines for non-compliance & even in some cases court decisions and actions.

Consequently, this is crucial and compulsory to make sure that equipment used are giving accurate results and thus calibrated by an independent third party with some minimal uncertainties

Enviro’ & Industrial Solutions ME experience and reference calibration systems could deliver such services in a very short time since we have all certified equipment in our laboratory in Dubai. Moreover, all our generated mixtures are controlled and certified by a set of reference analyzers.

Scope of Calibration

Scope of Calibration

  • Ambient Air Quality Monitoring Systems: reference analysers, Near/Non Reference portable or handheld analysers.
  • Indoor Air Quality Monitoring Analysers: handheld equipment, stationary detectors, parking gas sensors.
  • Stack Analysers: stationary emission monitoring systems, portable stack gas analysers
  • Noise Monitoring Instruments: stationary noise monitoring terminal, handheld sonometers.
  • Other Parameters: temperature sensors, pressure sensors, water calibration (FTIR Analysers).
