35-3000RK-LEL LEL Sample Draw Assembly in NEMA 4X Enclosure by RKI Instruments

The 35-3000RK series is a compact sample draw detector assembly with a built-in pump that accepts a 24VDC input. This unit features a NEMA 4X enclosure making it dust, water and corrosion resistant. It also features a flowmeter with adjustable flow and a low flow alarm which warns of any obstructions or restrictions in the flow system. Combustibles, oxygen, hydrogen sulfide and carbon monoxide versions are available with or without a 4-20 mA transmitter. The 35-3000RK is also available with both LEL and oxygen sensors in one unit.

The 35-3000RK is capable of single person calibrations and remote sampling at up to 5,000 ft. from a controller, and interfacing to any RKI or third party control system (utilizing a 4-20 mA feedback signal). Multigas versions of this efficient sample draw system are available with up to four sensors, LEL, O2, H2S and CO all in one enclosure. This is a very cost effective way of monitoring for several gases that may be in the same place.
