This pipe-clamp thermometer is designed for fast, simple servicing and troubleshooting across refrigeration, air conditioning and heating systems. Its probe uses advanced temperature sensor technology to deliver highly accurate readings that outperform standard thermocouples, ensuring consistent and efficient measurements. It features 2-display modes: a digital screen that shows real-time current temperature data, and a waveform mode that displays temperature and time curves on a dedicated coordinate grid, with 1-data set collected every 150-seconds. The 0.96 in. HD backlit color screen allows for intuitive readings in both bright and low-light environments, and supports switching between Fahrenheit and Celsius temperature scales. It automatically stores up to 8-sets of data, with a beeping alert once storage is full, and enters standby power-saving mode to conserve battery life when not in use or after 5-minutes of idle operation. Note that the screen may appear reflective under strong sunlight.
