Portable composite air quality analyzer is used to accurately detect and analyze a variety of gas concentration and environmental temperature and humidity, using 3.5-inch high-definition color screen real-time display, using the international famous brand of gas sensor, the main detection principle is: electrochemistry, PID photoion, etc. Swiss high precision capacitive digital temperature and humidity sensor. Advanced circuit design, mature kernel algorithm processing, unique shape design, suitable for the detection of gas concentration in the pipeline or confined space, atmospheric environment;

major function

Can simultaneously detect 1~6 gases, can be extended to 18 gases, units are free to switch units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

Built-in pump suction measurement, integrated water vapor and dust filter, rapid response, support long distance sampling, and built-in water vapor and dust filter to prevent sensors and instruments to damage due to water vapor and dust, which can be used for high humidity and high dust environment; sampling distance is more than 10 meters, special gas path design, matching corresponding accessories to detect negative pressure or positive pressure-0.5~2 kg, no impact on the measurement results.

Rich man-machine interface, 3.5-inch HD color screen, display real-time concentration, alarm, time, temperature, humidity, storage and other information; the menu interface uses HD simulation graphics to display the function name of each menu.

Large capacity data storage function (larger capacity can be customized), support a variety of storage methods, optional remote wireless transmission function.

Standard storage capacity of 100,000 data; optional U disk storage and SD card storage functions, support real-time storage, timing storage, or only alarm concentration data; support local view and delete data, upload to the computer through USB, RS232 interface or infrared communication for data analysis or printing.

A variety of communication interfaces and printing functions: infrared communication interface, RS232 interface, USB interface automatic identification, optional built-in or external wireless Bluetooth printer.

High temperature gas detection (optional): optional high temperature sampling cooling filter handle or high temperature and high humidity pretreatment system can detect the flue gas of 1300 degrees. Gas detection of other temperatures can be customized.

Three display modes can be switched: 1~6 kinds of gas concentration at the same time, the big character cycle shows the concentration of single channel gas, and the real-time curve is displayed.

Graphical display reflects the trend of gas concentration over a period of time

Data recovery function, in case of misoperation can choose a partial or full recovery

You can set whether the maximum, minimum, and average values are displayed

Standard USB charging interface, with charging protection function, support USB hot plug, charging state instrument can work normally

Support real-time detection or timing detection, when not detecting, the pump can be turned off to extend the startup time

A variety of alarm methods, alarm when the multi-directional three-dimensional indication alarm state including sound and light alarm, display screen visual alarm.

The alarm types include: concentration alarm, undervoltage alarm and fault alarm.

Multiple alarm mode settings: low alarm, high alarm, interval alarm, TWA / STEL alarm

Misoperation identification function: concentration calibration misoperation automatic identification and prevent, can avoid the bad caused by human factors

Zero point automatic tracking, long-term use is not affected by the zero point drift

Target point multilevel calibration to ensure measurement linearity and accuracy

The Chinese and English interface is optional

Log record: record the calibration log, maintenance log, fault record, fault resolution countermeasures, sensor life expiration reminder, and the next concentration calibration time reminder function.

application scenarios

Petroleum, chemical industry, medicine, environmental protection, flue gas analysis, air treatment and all other occasions that need to detect and analyze the concentration of gas.
