The on-site display and output signals are not influenced by the external environment (altitude, etc.).
Integrated collection system design that efficiently ensures airtightness
The collection system occupies one vent, reducing the chance of leakage
Remote-style density monitor and dew point sensor for in-situ collection and processing and simultaneous reporting of density, pressure, temperature and micro-water content
Collectors apply RS485 communication mode, facilitating on-site networking and commissioning
