UT331 Temperature Humidity Meter

The UT331 Temperature Humidity Meter is a professional environmental measuring instrument designed to monitor both temperature and relative humidity accurately. Engineers, laboratory technicians, HVAC professionals, and facility managers commonly use this device to monitor environmental conditions in warehouses, laboratories, factories, and storage facilities. As a result, it helps maintain proper climate conditions for sensitive equipment, materials, and products.

Moreover, the UT331 Temperature Humidity Meter uses high-precision sensors to detect temperature and humidity in real time. The instrument processes the collected data and displays the measurement values clearly on the LCD screen. Therefore, technicians can quickly evaluate environmental conditions during inspections or maintenance tasks.

In addition, the device provides a wide temperature measurement range from −20°C to 70°C, making it suitable for monitoring indoor environments and storage facilities. Because of this range, users can easily monitor cold storage rooms, office spaces, laboratories, and industrial production areas.

Furthermore, the UT331 Temperature Humidity Meter measures relative humidity from 0%RH to 99.9%RH with high accuracy. This capability is important in applications where humidity control affects product quality, such as pharmaceutical storage, food processing, electronics manufacturing, and environmental testing.

Another advantage of this device is its data storage capability, which allows users to store up to 299 measurement records for later analysis. In addition, the USB interface allows technicians to connect the meter to a computer and transfer recorded data for further evaluation using PC software.

The UT331 also includes useful monitoring functions such as MAX/MIN value display, data hold, LCD backlight, and automatic power-off. These features help technicians monitor environmental changes easily and read measurement results clearly even in low-light conditions.

Because of its reliable sensors, portable design, and data logging capability, the UT331 Temperature Humidity Meter is widely used in environmental monitoring, HVAC inspection, laboratory testing, and industrial climate control.
