Product Description

Veinasa-LD Dew-point Meter Compressed Air Dew Point Temperature Sensor RS485 Portable Dew Point Meter Analyzer
 

Product Description

Veinasa-LD is a dew point analyzer which adopts polymer sensitive capacitor, which has rapid response, stable and reliable, wide measuring range and high precision.

With automatic zero calibration and automatic hot cleaning function, good stability, can be used for a long time.
 

The product broke through the technical difficulties, and finally mastered the technology to improve the low humidity sensitivity. At present, when the Td changes from -70ºC to -50ºC, the basic capacitance changes from 300pF to 305pF, exceeding all the polymer dew point capacitors on the market.
