UNI‑T UT325 Digital Contact Thermometer

The UNI‑T UT325 is a high‑performance, dual‑input digital contact thermometer designed for precise temperature measurement across an extensive range of industrial and laboratory applications. Its robust construction, versatile sensor compatibility, and advanced data handling capabilities make it an indispensable tool for engineers, technicians, and researchers who demand accuracy and reliability.

Key Features

• Extremely Wide Temperature Range: From a low of -200 °C to a high of 1375 °C, the UT325 can monitor temperatures in harsh environments, including furnaces, kilns, and cryogenic systems.
• Dual‑Input Capability: Two independent measurement channels allow simultaneous monitoring of two distinct points or sensors, enhancing workflow efficiency and data correlation.
• Multiple Probe Compatibility: Supports a variety of thermocouple types—K, J, T, E, R, S, N—as well as RTD (PT100/PT1000), thermistor, and infrared sensors. This versatility eliminates the need for multiple devices.
• High‑Resolution Display: A clear, backlit LCD shows temperature values in Celsius (°C), Kelvin (K), or Fahrenheit (°F), with up to three decimal places for fine resolution.
• Data Logging and Analysis: Built‑in memory stores up to 10,000 data points per channel. Users can retrieve logs via a USB interface or directly view trends on the device.
• Alarm Functionality: Set upper and lower thresholds for each channel; the thermometer will trigger audible or visual alerts when limits are exceeded.
• Auto‑Power Off: Energy‑efficient design includes an automatic shutdown after a configurable period of inactivity, extending battery life in portable use.
• Robust Construction: The stainless steel housing and sealed probe connectors provide resistance to dust, moisture, and mechanical shock, ensuring reliable operation in demanding settings.
