美国英思科 iTrans 固定式气体检测仪

iTrans 固定式气体检测仪详细介绍：

微处理器控制的发送器能够独立运行或采用多点系统配置。配备板载继电器（选配）后，该监控器还可独立运行、激活报警、喇叭或风扇，也可在无需回线至中央控制面板的情况下关闭系统。

American intrinsic iTrans fixed gas detection instrument

ITrans fixed gas detection instrument in detail:

ITrans fixed gas detection instrument using intelligentelectronic platform, can provide one or two testing points from the single head, maximum flexibility, excellentperformance and lower installation costs.

ITrans used by the industry recognized "intelligent"sensor technology and safety features, including automatic recognition sensor, security access, as well aszero and calibration fault protection (detector is integrated in the explosion-proof aluminum or stainless steel housing), can monitor any gas compounds in the environment.

A microprocessor controlled can be run independently orwith a multi system configuration. Equipped with onboardrelay (optional), the monitor can run independently,activate the alarm, horn or fan, you can also turn off thesystem without the loop to the central control panel case.

Shell material: aluminum, multi cladding coating or 316 stainless steel, two were resistant to corrosion, explosion proof, NEMA 4X, protection grade IP66

Sensor type: combustible gas: catalytic combustion

Oxygen / toxic gas: electrochemical, infrared sensor
