Overview
Enviro Forest’s portable single gas detector with LCD display and customizable alarms offers reliable monitoring of a single gas with options for TWA and STEL measurements. This product is designed with an electrochemical, catalytic combustion, or PID sensor depending on requirements and provides accurate results with ±3% F.S precision and a fast response time under 30 seconds. It features a large STN LCD that clearly indicates real-time values and system status, even in strong light or from long distances. The device comes equipped with audible, visual, and vibration alarms reaching up to 85 dB, and users can request customization with no alarm if needed. Built with IP65 ingress protection and explosion-proof certification, it ensures durability and safety in demanding environments. A rechargeable lithium-ion battery supports up to 300 hours of continuous operation, while its compact, lightweight design with an alligator clip makes it easy to carry for industrial applications.
