This HVAC meter has a good relation between price and quality and it combines accuracy and versatility with the ability to transfer data directly to a computer. This air HVAC meter forms a part of a professional’s basic equipment to regulate and test ventilation systems. This HVAC meter is also used in research and development projects within institutions. Its fine 8 mm / .3 in point makes it possible to use in areas here there is limited space to measure, such as cooling systems. When a surface area is input into the HVAC meter it will calculate the volume of air current in m³/min. In this way, the capacity of a ventilation can be controlled and it can be used for air conditioning and refrigeration systems. It should be taken into account that when measuring air flow, various measurements should be taken and the average used to represent the air flow reading.
– Calculates volume of air current as well as average volume of air current
– Can be used for low air velocity
– Different units of measurement: m/s, km/h, ft/min, knots, miles/h
– Large LCD
– Easy to use
– Shows minimum and maximum value
– Save function for minimum and maximum values
– Auto shut-off function to protect battery life
– Has an RS-232 interface for data transfers to a computer
– Comes with a telescopic sensor, batteries, carrying case, software, RS-232 cable and user’s manual
Measurement range with corresponding unit: – m/s – °C / °F Calculation of volume of air current: – m³/min (CCM) | 0.2 … 20.0 0.0 … 50.0 / 32 … 122°F (sensor) 0 … 36,000 |
Resolution – Air velocity – Air temperature – Volume of air current (CCM) | 0.1m/s (for remaining units, up to ft/min = 1.0) 0.1°C / 0.18°F 0.001 to 1m³/min (depending on reading) |
