Toxic gas detector
The TG-4000 Hydrides Toxic Gas Detector from CEA Instruments is a direct digital reading, lightweight, portable instrument that utilizes a patented gas membrane galvanic sensor. It is designed to detect phosphine, arsine, silane, diborane, and hydrogen selenide well below their TLV`s without interference from hydrogen or organic solvents.
Weighing less than 1 lb., the rechargeable, battery-powered unit features quick response and is very specific to hydrides. Self-contained, it uses no paper tapes, reagents, or compressed gases. The TG-4000 has built-in audible and visual alarms and recorder output and comes complete with an extension probe and AC adapter.
