Two Gastech hydrocarbon detectors. Complete with charger, 5 foot hose and #1641 probe. Has no battery, so I couldn't test it. This came out of long term storage, and had labels indicating it had been serviced at that time. This device was used to detect and monitor oxygen and hydrogen sulfide levels. Marked "Intrinsically Safe" to use where flammable gases are present. Pick up in Nampa.
