Description
The UNI-T UT325F 4-Channel Digital Thermometer is a versatile temperature measurement instrument designed for professional and industrial applications. It supports seven thermocouple types: K, J, T, E, R, S, and N, allowing users to measure temperatures across a wide range depending on the selected probe.
With four independent input channels, the UT325F can monitor multiple temperature points simultaneously. It also provides MIN, MAX, AVG, and differential temperature measurements, making it useful for comparing temperatures between different locations or components.
The thermometer features a fast response time of approximately 500 ms and offers a resolution of 0.1°C/°F/K below 1000° and 1°C/°F/K at or above 1000°. Its accuracy is specified as ±(0.2% + 0.5°C) under the stated operating conditions.
For long-term monitoring, the UT325F can record up to 72,000 measurement records and supports programmable recording intervals from 1 second to 24 hours. Data can be transferred through Type-C USB or Bluetooth, allowing convenient connection to a computer or mobile device.
Its compact design, backlit display, data hold, automatic power-off, battery status indicator, and 1-meter drop protection make it suitable for both workshop and field applications.
