Product Description





The UT325F four-channel thermocouple thermometer comes with four standard K-type thermocouples and supports simultaneous measurement on all four channels. It can be used for multi-point temperature comparison or temperature difference measurement, featuring high precision and stable, reliable readings. It is compatible with various temperature probes (applicable to K, J, T, E, R, S and N type thermocouples) and has a powerful data logging function and analysis software. Data can be downloaded and analyzed via USB connection to a PC or Bluetooth connection to an app. It is suitable for temperature detection and recording in industries such as steel, metal processing, plastic processing, papermaking, electronics, and textiles.
