By removing the hassle of tangled cables, the UT320i allows rapid, reliable, and hands-free thermal readings on liquid and suction lines. Equipped with a clear, low-power digital LCD screen, technicians can monitor live pipe surface temperatures on-site while simultaneously broadcasting high-precision data across extended work sites.

Smart Connectivity and Effortless Workflow Integration

Designed to integrate into a connected diagnostic ecosystem, the UT320i synchronises seamlessly with the UNI-T UT336E digital manifold gauge for real-time calculation of superheat and subcooling. Furthermore, technicians can connect up to six individual UT320i units simultaneously using the dedicated mobile application. This multi-device support makes complex multi-circuit refrigeration, multi-split AC servicing, and large industrial pipeline balancing straightforward. The app supports Over-The-Air (OTA) firmware updates, real-time graphical monitoring, and instant report generation in standard PDF and CSV formats for immediate client documentation.

Rugged Reliability and Verified EU Safety Standards

Built to withstand demanding field conditions, the UT320i features an IP65 ingress protection rating, shielding the internal components from heavy rain, condensation, and fine construction dust. Its durable housing is rigorously drop-tested to survive impacts from heights of up to 2 metres. The high-temperature resistant jaw mechanism ensures consistent thermal coupling and long-term durability when attached to hot discharge lines up to 150 °C. Safety and quality are paramount: the UNI-T UT320i is fully tested and verified to meet strict European Union standards, carrying full CE and RoHS compliance for guaranteed professional safety.

Extended Runtime for Demanding Workdays

Power management is effortless thanks to an integrated 3.7 V 1400 mAh rechargeable lithium-ion battery. Delivering an impressive 180 hours of operational battery life even with active wireless data transmission enabled, technicians can conduct continuous monitoring and multi-day diagnostic logs without interrupting measurements. When power is required, modern USB-C charging ensures universal compatibility with vehicle chargers, power banks, and standard USB power supplies.

Safety Instructions

⚠️ Safety and Warning Instructions for Measurement and Testing Equipment

Before using our measurement and testing equipment (such as multimeters, current/ground fault clamps, voltage testers, laser and environmental measuring devices, laboratory power supplies, oscilloscopes, and testing and inspection tools), please be sure to observe the following warnings:

Electrical Safety & Voltage Hazards (Danger to Life)

  • Risk of electric shock: Check devices and test leads for damage (e.g., cracks in the insulation, exposed wires) before each use. Damaged devices or cables must never be used!
  • Measurement categories (CAT): Pay attention to the permissible overvoltage category (e.g., CAT III 600V, CAT IV 300V). Never use the devices in mains circuits that exceed the specified category or the maximum rated voltage/current.
  • Voltage-free condition: Perform resistance, continuity, diode, or capacitance measurements exclusively on voltage-free circuits. Capacitors must be discharged before measurement.
  • Fuses: Replace defective fuses in multimeters exclusively with the exact same type (usually high-resistance ceramic fuses with the same voltage and current specifications). Never bypass them!
  • Grounding & Lab Power Supplies: Operate mains-powered test equipment (e.g., oscilloscopes, lab power supplies, function generators) only from properly grounded outlets. Incorrect voltage or current settings on laboratory power supplies can destroy connected components, which can lead to fire or explosion (e.g., of electrolytic capacitors).

Laser Radiation & Optical Hazards

  • Eye injuries: Many devices (laser rangefinders, infrared thermometers, tachometers) use aiming lasers. Never look directly into the laser beam and do not point it at people or animals.
  • Reflections: Caution around reflective surfaces! The laser beam can be deflected and unintentionally strike the eye.
  • Risk of glare: Borescopes and inspection cameras often have very bright LEDs. Do not look directly into the light source.

Heat, fire hazard & environmental conditions

  • Risk of burns: When using thermal imaging cameras or contact thermometers to measure hot components (e.g., in industrial settings or on engines), there is a risk of accidentally touching hot surfaces. The measuring device itself does not protect against the heat of the test object.
  • Wetness & Moisture: Never use electrical measuring instruments in wet, damp, or extremely condensing environments unless they explicitly have a corresponding IP protection rating. Moisture inside the device can lead to fatal short circuits.
  • Explosion hazard: The devices are generally not EX-protected. Do not use them in environments containing explosive gases, vapors, or dust.

Mechanical hazards & handling

  • Rotating machine parts: When using tachometers, anemometers, or stroboscopes on running machines, there is an extreme risk of entanglement. Maintain a safe distance and do not wear loose clothing, have your hair down, or wear dangling jewelry. Ensure that test leads do not come into contact with moving parts.
  • Falls & Equipment Damage: A dropped measuring device (e.g., multimeter, insulation tester) may be internally damaged, which means protection against electric shock is no longer guaranteed. If in doubt, have the device tested at 230V before using it again.
  • Magnetic fields: Some devices or mounts contain strong magnets. Keep them away from pacemakers, magnetic data storage devices, and sensitive electronics.

General Information & Health

  • Technical expertise: Work on electrical systems (especially those operating at 50V AC / 120V DC or higher) must only be performed by appropriately trained professionals.
  • Batteries: Remove batteries/rechargeable batteries if the device is not used for an extended period of time to prevent damage and burns caused by leaking battery acid.
  • Children: These high-precision test and measurement devices are not toys. Keep them out of the reach of children.
