FHT-350 Series
Multi-Gas Detector

■ Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection, anti-static, lightning protection and anti-static capabilities; exceeds national standards and resists high-intensity pulse surge current impacts. High reliability and stability. Anti-reverse connection design, any form of reverse connection will not damage the instrument.

■ The standard infrared remote control can realize operations without opening the cover in dangerous situations, such as: modifying alarm points, concentration calibration, zero point calibration, silence, factory reset, entering menu, viewing records, 4mA output, 20mA output (this function is required to calibrate other collection equipment).

■ Chinese and English interfaces are selectable. The default Chinese interface supports free switching of gas concentration units. Conventional gases do not need to enter the molecular weight. Special gases will automatically calculate and switch after entering the molecular weight. Optional units are: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

■ The 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status and other information. It can detect 4 to 6 gas concentrations and temperature and humidity at the same time. The menu interface uses high-definition simulation icons to display the function names of each menu, and concise Chinese or English operation prompts.

■ Three display modes can be switched: displaying multiple gas concentrations simultaneously, large fonts cyclically displaying single-channel gas concentration and real-time curves, automatically or manually switching between channels, setting whether to display the maximum value, minimum value, and gas name, and viewing historical record curves.

■ Automatically tracks zero point to prevent drift, temperature compensation, multi-level calibration, and can simultaneously comply with national standards and local and provincial metrology bureau standards in various regions.

■ Data recovery function and concentration calibration misoperation automatically identify and block, which can avoid defects caused by improper operation.

■ It can record calibration logs, maintenance logs, fault resolution countermeasures, sensor life expiration reminders, and next concentration calibration time reminder functions.

Application fields

Petroleum, chemical industry, medicine, environmental protection, flue gas analysis, air management, tunnels and other places where fixed installation and online detection of gas concentration are required.
