TRSI TA623A Industrial Wall-mounted Thermometer Hygrometer, Built-in Probe

Features:
1. High-precision temperature and humidity sensor: Swiss SHT C3 high-precision sensor is used, with a sampling rate of up to 2 times/second.
2. Hidden retractable bracket on the back: There is an independent bracket on the back, which can be placed on the desktop.
3. Upper/lower limit over-limit prompt: The upper and lower limit alarm thresholds can be set for temperature and humidity respectively. When the measurement is higher or lower than the set threshold, there will be a buzzer alarm prompt sound, and the alarm prompt light will flash.
4. Four ventilation holes open windows: allow air to widely contact the internal sensor.
5. 13-inch large screen display, clear reading of numbers.
