产品描述

The HHAQ-109 gas concentration meter simultaneously detects Methane and Carbon Monoxide making it the ideal device for detecting gas leaks in mines, chemical plants, refineries and construction tunnels. The HHAQ-109 displays the current level of each gas as well as the STEL (short term exposure limit) and TWA (time weighted average). Concentration alarms are programmable in three modes (audible, visual and vibrating). The catalytic/electrochemical sensor uses natural diffusion sampling (typical sensor life 2 years).

The HHAQ-109 is powered by a rechargeable lithium-ion battery and includes the charger.
