เครื่องตรวจจับแก็ส Compact Multi-gas Detector for H2S, CO, O2, LEL Combustibles
The QRAE II is a full-featured, compact, one- to four-sensor gas detector for oxygen, combustibles, hydrogen sulfide, carbon monoxide or sulfur dioxide. Key features include easy-to-change battery pack, a water-resistant case and a new state-of-the-art O2 sensor. Made in USA
Key Features::
- Patented SPE O2? Oxygen sensor unique features:
- Lead-free design that complies with RoHS directive
- Extended life compared to lead-type electrochemical oxygen sensors, resulting in a low cost of ownership
- Leak-free design, minimizing downtime
- Best EMI/RFI immunity technology for products in its class, eliminating radio interference
- Easy access to pump, sensors, filter and battery compartment without exposing electronic components to potential damage
- IP-65 water- and dust-resistant case
- Strong, protective, concussion-proof design
