Portable Dew Point Meter
Model : ZA-3500
MFR : Henan Zhiyi System Engineering Co., Ltd
ZA-3500 Portable Dew Point Meter takes high-performance dew point transmitter and integrates multiple up-to-date research achievement and proprietary technology in measurement of dew point. It has the function of SF6 moisture automatic conversion in standard condition and software upgrading. It is one of existing dew point measurement instruments with the most advanced technique and the most powerful function.
Non-toxic discharge device is optional to protect your working environment
- Micro automatic conversion in standard condition (ppms accords with the latest national standard).
- Self-calibrating of zero point and slope at starting up (proprietary technology).
- Calibration of dew point with full-scale range by single-point method (proprietary technology).
- Sensor drying protection device (proprietary technology).
- Storage and printing of measurement data.
- Intelligent prompting of electricity quantity, intelligent charging protection.
- Lithium battery supply super-long standby.
- SF6 gas non-toxic discharge device internal and print function (optional).
