About Testo Manifolds
Testo manifolds are advanced digital instruments designed for HVAC/R professionals to measure and analyse parameters in refrigeration and air conditioning systems. They replace traditional analog gauges, offering enhanced accuracy, efficiency, and functionality.
Key Measurements
- Pressure: Accurately gauge high and low-side pressures within systems.
- Temperature: Measure temperatures using connected probes, facilitating real-time superheat and subcooling calculations.
- Vacuum: Monitor vacuum levels during system evacuation to ensure thorough moisture and contaminant removal.
Applications
- Refrigeration system maintenance: For diagnosing leaks, checking refrigerant levels, and optimising system performance.
- Air conditioning system installation and repair: For verifying system pressures and temperatures.
- Heat pump maintenance: For ensuring proper system operation and efficiency.
In general, Testo manifolds are essential tools for any HVAC, refrigeration, and heating appliance task requiring accurate pressure and temperature measurements.
