NEERI has facility for the calibration of rotameter, pump, Hi-volume sampler, Respirable dust sampler and top loading calibrator, required for air pollution monitoring, in the Air Pollution Control (APC) Division. All our calibrating instruments are traceable to FCRI, Palakkad/NPL,New Delhi. Details of calibrating instruments and calibration charges for each parameter/test equipment are shown below. In addition we also have facility for undertaking comparative studies of Fine Particulate (PM2.5) sampler and particle size analysis.
