T40 II Rattler® ATEX single gas detector (CO, H2S or O2)

Robust, light and appreciated for its simplicity of use, the T40 II Rattler® gas detector is very popular with coastal collectivities (H2S detection), the medical field (emergency services) and sectors of activity where a risk of nitrogen leak could generate a decrease in the oxygen level in the ambient air.

In the presence of a hazardous gas concentration, the T40 Rattler II activates an audible, visual and vibratory alarm. The 95dB audible signal alerts the wearer even in very noisy environments. A large text-free display clearly shows the gas concentration and the 2-button navigation allows the alarm thresholds to be set. Thanks to the powerful backlighting, all indications are clearly readable in the dark.
