Announcing the 04 Series – Single Toxic Gas Personal Monitor

May 18, 2021

The 04 Series is a single-gas toxic personal monitor designed to operate for many years with field replaceable sensors and filters. Compared to its predecessor, the 03 Series, the 04 Series is able to monitor toxic gases such as HCN, NO2, PH3, and SO2. A dual gas version simultaneously monitors for both O2 and CO with a combo sensor. In addition to toxics and combo sensor, the 04 Series is available with an H2 compensated CO sensor.

The line of sensors is compatible with the GX-3R, GX-3R Pro, as well as the GasWatch 3. With a protective rubber boot and an IP-67 rating, the 04 Series is built to operate for a long time. In fact, the 04 Series can operate 3,000 hours on one pair of AAA alkaline batteries. All versions of the 04 Series receive a 30% discount off list price and carry a 3-year warranty.
