Product Description 
 CZC5 ventilation parameter detector 'barometer basis points Determination', on the ventilation of the mine tunnel resistance and ventilation parameters were measured to help staff understand the resistance of the mine ventilation system the distribution of various safety measures for mine development and provide the basis for the implementation of the mine ventilation design, network solution, transformation of ventilation systems, fire control, and provide a reliable basis for information. The instrument can mine basis points, the points of absolute pressure, differential pressure, temperature, humidity, wind speed measurement and storage, combined with supporting software and automatically calculate the ventilation resistance data, analysis and measurement results, generated resistance maps and summary reports. 

 Instrument characteristics 

 FSTN display, Chinese menu guide user actions, display time, the remaining power and other functions 
 Can be automatically shut down when you can set the backlight and button sound, automatic standby function, less electric 
 Each instrument can be measured up to 512 measuring points, each measured point can store 32 sets of data, and can view data and memory usage, fast communication with the computer through the USB interface 
 Basis points and the measuring point two measurement modes, measurement basis points can be automatically recorded or manual records, automatically record the user can set the recording time interval, the instrument can record their own user-friendly 
 Measured point data vector preservation, measuring points and base data according to the test time to save a lot of time than the combination of time for subsequent data processing 
 Battery-powered, no backlight can work 20 hours or more, the backlight can work 15 hours or more
