PID and VOC Monitors

PID (photoionisation) monitors measure volatile organic compounds (VOCs) in ppm or ppb for contaminated land, remediation, solvent handling and industrial hygiene. Benzene-specific PIDs measure benzene on its own. All PIDs are calibrated with isobutylene, with correction factors for individual compounds. Hire a PID from £135 a week, a benzene PID from £185, or calibrate yours from £140.
