Arrgh Mark IV

Description

Arrgh’s Mark IV hydrogen detector is designed for unattended battery installations or remote shelters containing lead acid batteries and charging systems where hydrogen gas could be emitted when charging. The lower explosive limit for hydrogen in the atmosphere is 4%. The Mark IV is designed to turn on an exhaust fan if the gas level reaches 1%, and generate an alarm if the concentration reaches 2%. This alarm consists of local 80db horn, a flashing red LED, and a dry contact switch closure for reporting to a remote alarm system.

In addition to protecting your property and employees, cost savings are also realized. Insurance premiums may be reduced as a result of a hydrogen gas detector installation. Electricity costs decrease as a result of controlled exhaust fan operation rather than continuous fan operation. Air conditioning and heating costs are also reduced as a result of the controlled fan operation.

Two models are available: AC or DC. Optional accessories include a steel junction box for mounting on wall or ceiling, a remote panel for eye level placement, and modular cable for connecting the remote to the detector.
