1. Product Description
GT903-Y4 portable four-in-one Detector, suitable for a variety of industrial environments and special environment of composite gas concentration detection, using imported electrochemical gas sensor and microcontroller technology, fast response, high measurement accuracy, good stability and repeatability, the performance of the whole machine in the top level in CHINA, the parameters can be customized by the user, simple operation. Built-in 4000mA large-capacity polymer rechargeable battery, ultra-long standby, 2.4-inch industrial-grade color screen, good display of various technical indicators and gas concentration values, can view historical data on the screen, with storage, data export, temperature and humidity detection and other functions
Second, the characteristics of the instrument
(1) Ultra-low-power 32-bit microprocessor using a new semiconductor nanoprocess
(2) 2.4-inch industrial-grade color screen with a resolution of 320x240
(2) PPM, %VOL, mg/m3 can be switched freely
(3) With data storage function, a single channel can store 30800 sets of data, can intuitively view historical data on the screen, and can export data
(4) It has the function of temperature and humidity detection, which can detect the temperature and humidity value of the gas in the site or pipeline (optional)
(5) Various modes can be adjusted: detection mode, storage mode, display mode, air pump mode
(6) Built-in powerful air pump, which can work in a slight negative pressure environment, and a reasonable air chamber design can ensure that the sensor is not disturbed by pressure
(7) It has the functions of over-Voltage protection, over-charge protection, anti-static interference, anti-magnetic field interference, etc
(8) Full software automatic calibration, sensor up to 6 levels of target point calibration function, to ensure the accuracy and linearity of measurement, and with data recovery function
(9) Full Chinese/English operation menu, simple and practical
(10) With temperature compensation function, the instrument is dustproof and equipped with dust filter, which can be used in various harsh occasions
Third, the implementation of standards
