The handheld F-920 gas analyzer is specifically designed to measure the CO2 and O2 content in the air, as well as the gas content in modified atmosphere packaging, cold storage, laboratory and other environments. This product is easy to operate, weighs less than one kilogram, and can be easily carried for outdoor use. The built-in rechargeable lithium battery ensures continuous use for more than 8 hours. The built-in memory card can record time and date, relative humidity, temperature, gas concentration, and GPS location. F-920 is the best cost-effective product for measuring gas environment and concentration of gas components inside packaging.
[Instrument Features]
1. Continuous detection mode: The gas sampling rate is 70mL/minute, and the built-in pump continuously extracts air and displays the detection results on the screen in real time. At the same time, the detection results can be stored on the SD card at 1-second intervals. The built-in rechargeable battery can ensure continuous detection for more than 8 hours;
2. Headspace detection mode: The instrument extracts a certain amount of gas to be tested (with an adjustable inhalation volume of 7-29.9ml) until the sensor reading is relatively stable. The gas reading result will be displayed on the screen, and the amount of gas that has been inhaled will also be shown.

*Accuracy description: The accuracy calculation is "absolute accuracy+relative accuracy". For example, if the CO2 concentration reading is 6% in continuous detection mode, the accuracy calculation method is (absolute accuracy 0.1%+measured value 6% x relative accuracy 3%)=± 0.28%.
