The Spartna SPR-703 is a portable, intrinsically safe pumping multi-gas detector that measures Ex (LEL), O2, CO and H2S. It offers pump suction detection switchable to natural diffusion, a response time of 30 s or less, and an LCD with LED, sound and vibration alarms. Suited to gas leak detection in explosive environments and underground pipelines, it is powered by a 2000 mAh lithium battery in an IP65 housing.
