Description
Compressed Air Quality Multifunctional Tester
The compressed air quality multi-functional meter features data recording capabilities, making it an ideal and portable device for measuring compressed air or gas flow rate, pressure dew point, temperature, and more.
Portable dew point meter
The portable dew point meter can measure relative humidity, temperature, and dew point. In production operations, it is often necessary to ensure that the gas is dry enough to reach a specific dew point value. This meter is an ideal device for measuring dew point anytime, anywhere. It is convenient, fast, and does not require complicated power cords. Upon request, the dew point display can be adjusted to other units at the time of manufacture: PPM, mg/m³, g/kg, or atmospheric dew point. Special models can even measure high-pressure air with a pressure of up to 350 kg/cm³.
Fixed-flow meter
Fixed-flow meters are primarily used for long-term measurement and monitoring of compressed air and gas system flow rates. They can also measure relative humidity, temperature, and dew point.
Fixed-compression-air flow meter
Fixed-compression-air flow meter mainly used for long-term monitoring of pipelines and measuring the flow rate of compressed air. It can display both instantaneous and total flow rates.
