35-3010

The RKI 35-3010RK 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 in many different combinations. Combustibles and oxygen versions can be supplied with or without a 4-20 mA transmitter. The 35-3010RK series can also be configured with RKI's super toxic sensors offering a wide range of detectable toxic gases.

The 35-3010RK is capable of single person calibrations and can be installed up to 500 ft. from a controller, and can interface to any RKI or third party control system (utilizing a 4-20 mA feedback signal). This is a very cost effective way of monitoring for several gases that may be in the same place, and for applications where the sensors cannot be located directly in the area to be monitored. The pump is capable of drawing a sample up to 50' from the sample point.
