The GX-3R Pro is the world’s smallest 5-gas monitor weighing only 4.58 ounces and fits in the palm of your hand (2.9” W x 2.6” H x 1.06” D). It simultaneously monitors and displays 5 different gases. In addition to monitoring standard confined space gases, LEL, O2, CO, & H2S, the GX-3R Pro has a 5th channel where you can add infrared or toxic gas sensors (Hydrogen Cyanide (HCN) and Nitrogen Dioxide (NO2) sensors are currently available for the GX-3R Pro). Two of the four sensor slots have interchangeable sensors providing flexible configurations, which can easily be changed in the field.
