Temperature Meter Unit UT305C+ — handheld digital thermometer for contact and non-contact measurement

The Temperature Meter Unit UT305C+ is a handheld digital thermometer by Unit designed for both contact and non-contact temperature measurement. The instrument provides quick surface and ambient temperature readings on a clear digital display, enabling fast verification during HVAC inspections, equipment diagnostics, food safety spot checks and routine maintenance. Its portable form factor and simple controls support practical field use and rapid decision-making.

Advantages

The UT305C+ combines contact and infrared non-contact measurement modes in a single device, reducing the need to carry multiple instruments. A responsive digital display shows measured values clearly, and the compact housing makes the unit easy to transport and operate with one hand. The thermometer is intended for straightforward temperature checks and integrates both surface probe and IR sensor functionality for versatile measurement options.

Suitable for

• HVAC system inspections and troubleshooting
• Routine maintenance of electrical and mechanical equipment
• Spot checks for food surface and ambient temperature
• Laboratory bench checks and general-purpose temperature verification

Key specifications

• Measurement modes: contact (probe) and non-contact (infrared)
• Portable handheld design with digital display
• Fast readout suitable for spot measurements
• Designed for surface and ambient temperature measurement
• Simple user controls for switching measurement modes

How to use

Select the appropriate measurement mode for your task — use the contact probe for direct surface or object measurement and the non-contact infrared function for quick surface or distant readings. Aim the IR sensor at the target from a reasonable distance and press the measurement button to obtain a temperature reading on the display. For contact measurements, place the probe firmly on the surface and wait for the display to stabilize before recording the value. Power the device according to the manufacturer's instructions and replace batteries as needed to maintain reliable operation.

Usage recommendations

When using the non-contact infrared mode, ensure the measurement distance and the target area are appropriate and free from obstructions or condensation. For most accurate contact readings, clean the probe tip and ensure good thermal contact with the measured surface. Use suitable personal protective equipment when measuring hot surfaces or when working near live equipment.
