Description / Features / Spec


QRAE 3 Pumped ATEX LEL/H2S/CO/O2 - Li-ion/Non-Wireless

The QRAE 3 from RAE Systems by Honeywell, is a four-gas wireless detector.  It’s capable of detecting one to four gases.  This particular model detects LEL and combustibles, carbon monoxide (CO), oxygen (O2) and hydrogen sulphide (H2S) and is a pumped unit.

This multi gas detector can provide real-time readings wirelessly, as well as 24/7 alarm statuses.  The allows better visibility and will also improve response time.   Being a pumped unit means it is ideal for confined space applications.  Other applications and industries that the QRAE 3 is suitable for are industrial safety, oil and gas, fireground “Toxic Twins” detection, environmental and fire and emergency response.

The QRAE 3 can be easily maintained with easy access to the pump, sensors, filter and battery compartment.  The sensors and pump can be easily replaced.  It has integrated continuous data logging capability (3 months for 4 sensors at 1-minute intervals, 24/7) and a triple alarm system (audible, vibration and visible LEDs).
