Testing, adjusting and balancing are essential steps in ensuring efficient operation of heating, ventilation, air conditioning and refrigeration (HVAC/R) systems. Uni-Trend offers a comprehensive range of professional HVAC test instruments designed to support accurate system diagnostics, maintenance and optimisation.
The range includes commonly used tools such as thermal imagers for detecting hot and cold spots, as well as flow meters for measuring air and liquid flow. Uni-Trend HVAC meters help professionals optimise airflow, evaluate room pressure, identify temperature variations and accurately measure key parameters such as current, voltage, pressure, continuity, vibration, power, refrigerant leaks and temperature.
Once the required vacuum level has been achieved, attach the refrigerant cylinder and use an electronic refrigerant scale to measure the correct charge while adding the refrigerant gradually to the system.
After charging, monitor the system’s operating pressure and temperature to confirm that both remain within the specified working range.
During refrigeration system installation, commissioning or troubleshooting, measure and record the pressure and temperature on both the high-pressure and low-pressure sides of the system.
The UT336E Digital Manifold Gauge and UT336P Wireless Pressure Gauge are compatible with multiple refrigerant types and provide real-time pressure and temperature monitoring. They also support useful functions such as data storage, Bluetooth connectivity to the mobile app and data export, helping technicians record and analyse system performance more efficiently.
System vacuuming removes trapped air and moisture from the refrigeration circuit, helping improve operating efficiency and support reliable long-term system performance.
Once the required vacuum level has been achieved, connect the refrigerant cylinder and use an electronic refrigerant scale to measure the correct charge as the refrigerant is gradually added to the system.
