AUTOOL LM55 digital thermometer is a precise measuring instrument for heating and cooling systems and is thus ideal for all HVAC/R contractors and technicians.

Features:
1.【Upgraded HVAC Thermometer】LM55 digital Temperature clamp meter is equipped with a a high-precision temperature sensor, with a temperature error within ±0.3℃. AUTOOL HVAC Thermometer can display the current temperature data in real time, measuring range -20℃-150℃.It can quickly and accurately detect the Refrigerant piping temperature.
2.【Real-time Temperature Measurement】The AUTOOL hvac thermometer provides a real-time digital display of the current measured temperature, measuring range -50℃-150℃. The temperature is displayed as a waveform and the temperature/time curve is displayed in real time.It can store 8 sets of waveform data, with each set of data lasting 150s,and users can browse historical waveforms.
3.【Data Waveform Display】LM55 HVAC Thermometer displays data in waveform form, real-time data and historical data can be displayed,the vertical axis represents temperature in degrees Celsius (°C) or degrees Fahrenheit (°F),(freely switched).It can store 8 sets of waveform data, with each set of data lasting 150s.When 8 sets of data have been stored, the device will stop storing and a buzzer will sound for 15 seconds to alert the user.If there is no user activity or if the real-time waveform mode has collected 8 sets of data for more than 5 minutes, the system will enter standby mode.
4.【High-definition Color Screen】AUTOOL HVAC digital thermometer is equipped with a 0.96-inch TFT color screen, with a resolution of 80RGB x 160 dots. LM55 HVAC Thermometer only have two buttons,the Toggle button and the Enter button.The main interface have test,wave and setup functional icons.Temperature units can be freely selected in the setting page, and the backlight brightness can be freely adjusted as needed (0%-100%).
5.【3 years Warranty】For damage caused by non-human factors,AUTOOL promise to resend parts for free within 3 years. For any needs,you are warmly welcomed to contact us and we will get back to you ASAP within 24 hours.
