HHNPZH-90 Comprehensive Tester

Overview
The HNPZH-90 comprehensive tester is an upgrade of the HNPZH-80 comprehensive tester. Under the premise of software version optimization, the dew point measurement principle is changed from the resistance-capacitance method in the HNPZH-80 to the cold mirror method to make the dew point measurement more accurate.
More advanced A/D chip in this instrument is more sensitive to the changes of trace data, so the overall precision is better than that of the previous model. However, due to the dew point measurement by means of cold mirror method, the power consumption of the system is slightly increased. In case of outdoor use for a long time, it is recommended to use a special external power supply module.
Main Features
Any combination of humidity, purity, decomposition product test modules and software to improve work efficiency
The humidity is automatically converted to the humidity value at normal pressure and 20°C, more conforming to the electric power standards
Advanced sensor in the world to ensure the measurement precision
Self-diagnosis function
Data upload and measured value output in the form of EXCEL sheet in combination with the host computer software
Temperature compensation and detection end point judgment
