Thermal Clamp -50 to 260°C ±0.3°C Data Memory

【Accurate Measurement】The HVAC clamp thermometer incorporates an industrial-grade sensor offering ±0.3°C accuracy over a wide measuring range of -50°C to 260°C. It provides stable and reliable readings, suitable for HVAC, refrigeration, and automotive air conditioning maintenance. 【Dual Display】The pipe temperature tester displays the real-time value and dynamically tracks the temperature curve. It can store 8 sets of data, each 150 seconds long, with history playback and an alert when the memory is full, for more convenient measurement management. [Customizable Screen] The digital pipe thermometer features a 0.96-inch color screen with adjustable backlight brightness from 0 to 100. It allows instant switching between °C and °F, color and black and white modes, and a bilingual Chinese and English system. [Wide Compatibility] The clamp temperature meter supports manual fine calibration of ±10°C to maintain measurement accuracy over time. Its robust clamp fits pipes up to 40 mm (1.5 inches) in diameter and accommodates most common pipe sizes. [Energy Saving] The LM55 digital clamp thermometer operates on 3 standard AAA batteries (not included) and has a standby power consumption of less than 500 µA. It features an automatic shut-off after 15 minutes as well as a continuous operation mode, depending on your monitoring needs.
