● Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection and anti-static capabilities, exceeding national standards, with resistance to high-intensity pulse surge current impact. High reliability and stability. Reverse connection protection design, no damage to the instrument even in any reverse connection situation. ● Standard infrared remote control, enabling operation without opening the cover in hazardous scenarios, such as modifying alarm points, calibrating concentration, calibrating zero point, silencing, restoring factory settings, entering the menu, viewing records, 4mA output, 20mA output (this function is required for calibrating other acquisition devices). ● Chinese and English interface options, defaulting to Chinese interface, supporting free switching of gas concentration units. For conventional gases, no molecular weight input is required; for special gases, inputting the molecular weight will automatically calculate and switch units. Available units: PPM, mg/m³, Vol%, LEL%, PPHM, ppb, mg/L. ● 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status and other information. It can simultaneously detect 4 to 6 gas concentrations, temperature and humidity. The menu interface uses high-definition simulation icons to show the function names of each menu, with concise Chinese or English operation prompts. ● Three display modes can be switched: simultaneous display of multiple gas concentrations, large-font cyclic display of single-channel gas concentration, and real-time curve. Automatic or manual cycling between channels is switchable. It can be set to display maximum value, minimum value and gas name, and historical record curves can be viewed. ● Automatic zero tracking to prevent drift, temperature compensation, multi-level calibration, capable of meeting both national standards and local/provincial metrology bureau standards in various regions. ● Data recovery function, automatic identification and prevention of misoperations in concentration calibration, avoiding adverse effects caused by improper operation. ● Capable of recording calibration logs, maintenance logs, fault resolution countermeasures, sensor life expiration reminders, and next concentration calibration time reminders.
