ZA-3502 Portable Dew Point Meter
ZA-3502 adopts imported film capacitive humidity sensor and microcomputer technology is developed as an intelligent trace moisture measuring instrument with good performance. Its operation is simple and it has the function of conversion among Td, RH, PPM and software upgrade. It can measure the content of trace moisture in various gases.
- Imported high performance built-in full compensation film capacitor dew-point sensor (Finland VISALA)
- Zero-point and slope self-calibration after start, dew point calibration by single point way for full range (patent technology)
- Sensor dry protection device (patent technology)
- Unique gas circuit design, good gas tightness, and permeability, water resistance.
- Large screen TFT liquid crystal displays dew point value and the corresponding RH % relative humidity value, PPM moisture value
- Color touchscreen control, Chinese/English operation menu
- Measurement data storage and query
- Intelligent power prompt, intelligent charging protection
- Lithium battery offers power supply long standby
