Features:
1. Four parameters measurement, ambient temperature, ambient humidity, dew point temperature, wet bulb temperature, can display two lines of data at the same time
2. High precision temperature and humidity sensor
3. Upper/lower limit exceeds the limit prompt: temperature and humidity can set the upper and lower limit alarm threshold; when the measurement is higher or lower than the set threshold, there will be a buzzer alarm prompt sound, as well as alarm prompt light flashing
4. VA high-definition color screen display with background lighting
5. Two power supply modes: battery and USB interface
6. Data logging records:
- Interval length can be set to: 5s/10s/30s/60s/30min/60min/12h/24h, a total of 8 gears
- TA622B can export and generate charts by communicating the data recorded by the host computer with the PC software through the USB interface
7. USB computer communication (only TA622B) has the ability to download recorded data, communicate with computer in real time, display real-time data tables and real-time data graphs; export and print xlsx data tables and graphs; the upper computer software is applicable to computer systems Win7, Win8, Win10
