Working Principle

The TP101 AUTO A/C THERMOMETER uses a DS18B20 digital temperature sensor. The metal probe transfers the measured temperature to the sensor chip, which directly converts the temperature into a digital signal. The mainboard receives and processes the digital signal, and the display outputs the temperature reading in real time. The device supports °C/°F unit switching for convenient temperature measurement.

Features

DS18B20 Digital Temperature Sensing:Digital signal transmission provides excellent interference resistance, stable and reliable readings, and reduced measurement errors caused by signal drift.

Metal Probe for A/C Outlet Measurement:The metal probe can be inserted deep into the air outlet to measure the actual outlet air temperature, with a fast temperature response.

Compact Handheld Design:The compact, handheld design makes the thermometer easy to operate, carry, and store.

Wide Measurement Range:The measurement range of -10 to 80°C (14 to 176°F) meets the temperature testing needs of automotive A/C cooling and heating conditions.

Clear and Precise Readings:With an accuracy of ±2.0°C (±3.6°F) and a resolution of 0.1°C (0.2°F), temperature changes can be clearly identified.

Dual Temperature Units:Supports one-touch switching between Celsius (°C) and Fahrenheit (°F).

Wide Operating Temperature Range:With an operating temperature range of -10 to 60°C (14 to 158°F), it is suitable for varying workshop environments.
