 midwest-group 1, functional overview 


 Companies use DRYCAP ? humidity sensor for industrial humidity measurement for nearly 60 years. DRYCAP ? high-quality electronic components with the perfect combination of intelligent, so successfully applied to a variety of instruments measuring humidity extremes of industrial environments. Provide the world with humidity measurements in the field of advanced technology. 
 DRYCAP ? thin film polymer capacitive sensor principle, be measured in the whole range of accurate and reliable, and has excellent long-term stability, most of it from dust particles and chemical pollution, very suitable for industrial use. 
 ZX7M-HNP series precision dew point meter is in the low dew point and dry point need to control ideal for industrial environments. It has chemical automatic cleanup option, which makes ZX7M-HNP series precision dew point meter high concentrations of chemicals in the cleaner environment and can perform precise and stable measurement, thus ensuring the accuracy of each measurement between calibration intervals. 


 2, the main features 
 ● does not drift, stable, reliable 
 ● Wide measuring range, high precision, fast response 
 ● probe condensation, special pollution, oil and most chemical environment is not affected 
 ● the use of patented technology to protect the gas chamber, speeds up the measurements and to protect the sensor life 
 ● Real-time measurement curve 
 ● Start the Zero calibration 
 ● portable intelligent, suitable for field operation 
 ● has a fast data storage and query functions 
 ● AC-DC dual-use, built-in rechargeable battery, can work for hours 
 ● pressure measurements can be directly measured inlet pressure. 
 ● calibration cycle is long, generally every two years
