Professional Diagnostics for HVAC and Refrigeration Systems

The UNI-T UT336P KIT is an advanced wireless digital pressure gauge tailored for air conditioning, heat pump, and refrigeration technicians. Precision and speed are critical when commissioning or servicing modern cooling equipment. This all-in-one kit eliminates bulky mechanical manifold gauges, combining high-precision pressure transducers with an external pipe clamp sensor to deliver rapid, reliable diagnostics directly into the palm of your hand.

Equipped with a standard 1/4 inch SAE connector, the gauge mounts directly to service ports on residential, commercial, or automotive air conditioning circuits. The integrated high/low pressure switch accompanied by coloured LED status lights—red for high pressure (HP) and blue for low pressure (LP)—prevents line confusion and speeds up routine maintenance. A dedicated zeroing function ensures reference baseline accuracy before every charging cycle or diagnostic session.

Integrated Temperature Clamp and Automatic Calculations

Calculating superheat and subcooling manually using pressure-temperature charts can introduce human error and consumes valuable time. When paired with the included UT-T19 temperature clamp, the UT336P instantly reads refrigerant pipe temperatures and calculates real-time superheat and subcooling values. The long 2-metre cable allows flexible positioning on suction lines or liquid lines even in tight condensing units. Technicians can view all critical parameters simultaneously on the crisp, backlit screen or track dynamic variations live within the free iENV companion app.

Extensive Refrigerant Support and Long-Term Offline Logging

Modern HVAC installations demand versatility across various refrigerants. The UT336P KIT supports over 94 refrigerants, coming pre-configured with 10 widely used selections and allowing straightforward switching between types via the app. The hardware is compatible with standard A1, A2, A3, and mildly flammable A2L refrigerants (note: not suitable for ammonia/R717 systems). For troubleshooting intermittent faults or verifying system stability after commissioning, the device features standalone offline data logging. It records up to 8,000 data sets at programmable intervals ranging from 1 second to 1 hour, without requiring a permanent smartphone connection.

Safety, Compliance, and Heavy-Duty Field Reliability

Built to meet the rigorous demands of industrial and field technicians, the device features a rugged casing rated to IP54 against ingress of dust and water splashes. A built-in hook design and hand strap facilitate secure hands-free placement during long monitoring cycles. Safety and compliance are paramount for European trade professionals: the UNI-T UT336P KIT is fully tested and certified under relevant European standards, holding CE and RoHS certifications. Configurable acoustic and vibration alarms warn engineers immediately if pressure thresholds cross preset safety limits, preventing equipment overload and refrigerant loss.

Frequently Asked Questions (FAQ)

Can the UNI-T UT336P KIT be used with A2L refrigerants?

Yes, the gauge is fully compatible with A2L mildly flammable refrigerants, as well as A1, A2, and A3 categories. However, it must not be used with ammonia (NH3 / R717) systems.

Does the device require a continuous Bluetooth connection to record data?

No. The UT336P has internal offline storage that holds up to 8,000 readings. You can configure the logging interval in the app, let the gauge record independently on-site, and download the full dataset later via Bluetooth.

How are superheat and subcooling monitored?

Once you connect the UT-T19 temperature clamp to the 3.5 mm jack and clip it to the suction or liquid line, the unit determines the saturated temperatures based on the selected refrigerant pressure and automatically calculates superheat or subcooling on the display and in the iENV app.

What is included in the UT336P KIT package?

The kit comes complete with the wireless pressure gauge, one UT-T19 temperature clamp, a bent 1/4'' SAE adapter, a three-way tee connector, 3x AA batteries, a hand strap, a quick start guide, safety documentation, and a durable hard toolbox.

Does the tool comply with European safety directives?

Yes, the UT336P KIT strictly complies with EU health, safety, and environmental standards, carrying full CE and RoHS conformity markings for professional trade use.

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.
