Zareba ChemKey TLD Toxic Gas Detector
The ChemKey TLD Toxic Gas Monitor by Zareba provides a reliable solution for both emergency responses and fixed area gas detection in a cost effective manner.
Utilising the Gas Selection System exclusive to ChemKey, a single monitor is capable of monitoring over 50 different gases with just a change of the ChemKey and Chemcassette.
You are assured of substance specific, fast and sensitive exposure protection. Any danger of false alarms is never the case or results that are inaccurate caused by other commonly present chemicals.
Features & Benefits
 Battery operated or line powered
Low maintenance and no dynamic gas calibration
Variety of signals outputs to meet monitoring needs
Quick Specs
Detection technique: Chemcasstte Direction System
Response Time: As fast as 10 seconds
Alarm indication: Audio and visual alarms
