The professional CO warning and measuring device GX-C300P with internal electrochemical sensor is equipped with a vacuum system, which allows a hose to be placed in the room to be monitored. Either the room is very dusty (pellet and wood chip bunkers) or thermally demanding (gas-operated saunas or cold stores) or no electrical cables may be laid (explosion-protected), then the air intake is the only way to measure the CO concentration. No large quantities of air are required, a small vacuum in the warning device is sufficient to obtain correct measuring results after 30 seconds at the latest. For rooms with high dust loads, a filter is supplied, which is replaced if required, but at the latest annually. As standard, the device works strictly according to DIN EN 50291 standard, but can be adapted to your requirements before manufacturing.TUeV tested safetyCO-sensor, measuring cell, evaluation and software have been subjected to an extensive full test in accordance with DIN EN 50291 at
