HVAC thermometers

Pressure meters measure air or gas pressure across a wider range than standard manometers. They are used in industrial, HVAC, and engineering applications where higher pressures need to be monitored.

Gauge pressure measures pressure relative to atmospheric pressure. Differential pressure measures the difference between two pressure points, often used to monitor filters, ducts, or airflow.

Yes, manometers are commonly used to measure gas pressure in heating appliances and systems, provided the gas is non-corrosive.

Yes, regular calibration helps ensure readings remain accurate over time. This is important for maintaining confidence in measurements and supporting inspection or testing requirements.

You can send your manometer, pressure meter or anemometer to us for 3-point traceable recalibration at our UK laboratory. Learn more about our calibration services.

High-quality digital manometers provide reliable and repeatable readings when used correctly. Accuracy depends on the model and proper use, but they are designed for precise low-pressure measurement.

Manometers are used for tasks such as testing gas pressure, measuring flue draught, checking ventilation systems, and monitoring filter performance.

A manometer is a device used to measure air or gas pressure. It is commonly used to check pressure in HVAC systems, gas appliances, and industrial processes.

When selecting a thermometer for your industrial application, some common features to consider are:

• Waterproofness — protection from water and dust
• Range — the highest and lowest temperatures required
• Accuracy — the potential margin for error
• Hold — locking readings on-screen for easy recording
• Max/min — the maximum and minimum temperatures over a period
  

Accuracy requirements vary, but many industrial applications require readings within ±0.5 °C to ±1 °C. More critical processes may demand higher precision.

The best way to measure pipe temperatures is to use a pipe clamp temperature probe. These probes are specifically designed to maintain good contact with the pipe surface for greater accuracy. They can also be left in place while carrying out processes such as radiator balancing.

The best thermometer for radiators is a surface probe combined with a thermocouple thermometer. This method provides highly accurate results.

For quick checks you can use an infrared thermometer, or for a budget-friendly option you can choose a magnetic temperature dial.
