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

Robust, light and appreciated for its simplicity of use, the T40 Rattler II 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.

Main assets:
