Professional Deep Evacuation for Refrigeration and Heat Pumps
Proper evacuation is the most critical phase during the commissioning and servicing of modern HVAC and refrigeration circuits. Non-condensable gases and residual moisture drastically reduce efficiency, cause acid formation, and lead to premature compressor failure. The UNI-T UT336V wireless digital vacuum gauge provides service engineers and refrigeration technicians with the precision and reliability needed to ensure systems are thoroughly dehydrated before charging.
Equipped with an advanced pirani-style sensor system, the UT336V measures pressures from atmospheric down to 1 micron with exceptional detail. The unit supports all common international vacuum units, including microns, mBar, Pa, kPa, hPa, mTorr, Torr, mmHg, inHg, inH₂O, and psia. Whether installing residential split air conditioners, performing complex heat pump maintenance, or servicing commercial multi-stage refrigeration systems, the UT336V provides unambiguous data at every stage of the evacuation process.
Real-Time Bluetooth Monitoring and Reliable Documentation
Working on elevated outdoor heat pump units or inside plant rooms often requires technicians to move between the vacuum pump and control panels. Thanks to integrated Bluetooth technology, the UT336V pairs directly with your mobile device via the companion app. Real-time graphs and live data updates allow technicians to monitor vacuum progression from a safe distance, verify system tightness through pressure rise decay tests, and generate professional PDF or CSV commissioning logs for customer verification. Additionally, the instrument seamlessly pairs in real-time with the vacuum mode of the UNI-T UT336E digital manifold gauge.
Moisture Assessment and Target Vacuum Management
Evacuation is not merely about removing air; it is about evaporating trapped water. The UT336V features an integrated calculation of water saturation temperature alongside ambient temperature monitoring (-20 to 60 °C) to calculate ΔT (Tamb - TH₂O). This automated H₂O status assessment shows whether liquid water is still boiling off or if the system has reached true dry condition. Dual audio-visual feedback, including bright LED indicators and an audible buzzer, instantly alerts you once your pre-configured target micron threshold has been attained.
Certified Safety, Robust Build, and A2L Refrigerant Suitability
Modern heat pumps and cooling appliances increasingly utilise mildly flammable A2L refrigerants like R32 or natural hydrocarbons such as R290 (A3). The UNI-T UT336V is engineered for modern workshops and field environments, boasting broad compatibility across A1, A2L, A2, A3, and partial B1 refrigerants. Technicians can rely on confirmed industrial standards: the device fully complies with European CE safety requirements and RoHS regulations. Built into a durable casing rated at IP54, it offers dependable protection against splashes and airborne dust. An overpressure tolerance of up to 27.5 bar protects the delicate internal sensor elements should positive system pressures inadvertently be applied during manifold manipulation.

Frequently Asked Questions
Can the UNI-T UT336V be used with flammable A2L or A3 refrigerants?
Yes, the UT336V is compatible with modern A1, A2L, A2, A3, and select B1 refrigerants commonly used in heat pumps and cooling appliances. Please note that the gauge must not be used with ammonia (NH3 / R717) refrigerants.
What happens if positive pressure is applied to the gauge?
The UT336V is built with an integrated overload pressure rating of up to 27.5 bar, protecting internal sensing mechanisms from unexpected positive pressures during system servicing.
How does the H₂O status function assist in dehydration?
The gauge calculates the evaporation point of moisture by comparing current vacuum pressure with the measured ambient temperature (ΔT). This displays whether residual liquid water is actively boiling off inside the pipework or if true dehydration has been reached.
Can vacuum reports be saved and exported to customers?
Yes, connecting the gauge to the dedicated mobile app via Bluetooth allows real-time logging. Technicians can export completed evacuation and pressure rise decay graphs in standardized CSV or PDF formats.
What is included in the scope of delivery?
The package contains the UNI-T UT336V Wireless Vacuum Gauge, three 1.5 V AA batteries, a hanging hook, a protective hard cloth bag, a user manual, a safety guide, and a download operation guide.

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.
