The HVAC meter is a small and handy measuring device for determining the differential air pressure. The HVAC meter has a measuring range of ±5000 Pa. The HVAC meter is connected via two hose connections with a diameter of 8 mm.

• Measuring range: ±5000 Pa
• 11 different pressure units:Pa, hPa, mBar, mmH2O, mmHg, inH2O, inHg, psi, ozin², bar, kPa
• Medium: gaseous
• Zero point calibration

The HVACR tester detects air temperature and humidity and stores readings in its internal memory. The HVACR tester has a compact format and a wide memory capacity (up to 32,000 values / 16,000 values for each parameter) and it is mainly used as a HVACR tester in fields such as supermarket refrigeration units, refrigerated transport, warehouses, and other temperature controlled environments.

The HVAC Meter has been designed to detect, indirectly, AC/DC current and frequency. The HVAC Meter has a flashlight integrated to allow for the point of measurement to be illuminated, and a function to test the voltage without contact.

• AC current (50/60 Hz): 200 A / 0.1 A or 100-mA / ±3.0% + 8 digits
• DC current: 200 A / 100-mA / ±2.8% + 8 digits
• AC test voltage (without contact): 100 VAC to 600 VAC 50 / 60 Hz
• Frequency: 40 to 50 Hz / 51 to 510 Hz/ 0.51 to 1 kHz
