The ARA H2S gas detector is an inexpensive and easy-to-maintain hydrogen sulphide detector for safety monitoring. The portable gas detector has only one button, which makes it easy to operate and alerts users as soon as the level of the measured gas exceeds established safety standards.
The ARA H2S gas detector has a self-test feature that tests audible, visual and vibrating alarms to ensure that the device is functioning properly.
