Details: This is our heavy-duty 4-gas detector for continuous detection to ensure wellness and safety in confined work spaces, industrial operations, oil and gas, and manufacturing type of environments. Also useful in water purification, treatment facilities, chemical plants, high-technology manufacturing, silos, underground operations, maritime, tank, silos, and other confined spaces where ventilation can be limited. This unit tracks the traditional 4 gases comprising O2, CO, EX LEL, and H2S is required for the paramount safety of personnel. The 4-gas meter comes with high and low alarm settings that simultaneously trigger 1kW relays to control and trigger power equipment such as fan control, ventilation or additional alarms, sirens or control panel switching. Additional features include a remote control up to 8 meters, analog output (4 - 20 mA), and relay alarm triggered switches (1 kW) to control fans, pumps, or additional alarms. The alarm includes digital time stamping and logging of 1,000 data points. For those that just require a more basic 4-gas meter without the advanced multigas detector function, we recommend our 4-gas meter FD-4A. For those requiring a handheld 4-gas meter with a built-in pump, we recommend our FD-600-4GAS multigas detector.
Included: Comes with the 4 gas fixed wall mount detector, English manual, remote control with battery, hex key to remove the cover, 24V power adapter to plug to 110V outlet, and wiring. Arrives with a USA NIST calibration certificate.
