Formaldehyde measurement

	Automatic gas sampler Click here for [GSP-300FT-2] Details	Formaldehyde detector tubes [91P][91PL] (for use with Automatic gas sampler GSP-300FT-2)
Features Certified and approved by Japan Ministry of Health, Labour and Welfare for use with formaldehyde tubes 91P,91PL Since this device utilises detector tubes, on-site measurements can be obtained easily and quickly No calibration (standard) gas is required as standard detector tubes do not need calibration No highly specialised knowledge or training is required Less expensive than other sampling methods in terms of initial and running costs Employs a quiet air pump that is well suited for use in residential environments Detector can be extended or retracted as needed to obtain measurements anywhere from 60 cm to one metre from the floor Display shows how much sampling time remains and the air pump shuts off automatically after a preset sampling time (30 minutes)
