Instrument Features
•Good human-machine interface: Uses 320×240 graphic dot matrix LCD display, high resolution, clear graphic Chinese characters, multi-parameter display on one screen;
•Automatic pressure generation: The instrument has built-in "electronic pressure pump" and external "electric micro pressure generator" for automatic pressure generation;
•Automatic flow measurement: Uses dry cumulative flowmeter with photoelectric sensor to automatically measure instantaneous flow, automatically count average flow over measurement time, and automatically convert to standard condition flow;
•Automatic data statistics: After measurement, automatically calculates error at each point, automatically counts maximum error and determines whether the test result is qualified according to allowable error, eliminating the trouble of manual recording and error calculation, with more intuitive data recording;
•One machine with multiple uses: Built-in atmospheric pressure and temperature sensors, calibrated and compensated at factory, users can use directly;
•Automatic data storage: Automatically saves various calibration data, each set includes standard value, calibrated value, error, maximum error, record number, calibration points (quantity), allowable error, verification result, as well as current temperature, atmospheric pressure, date, and time. Each set can set 7 calibration points. Humanized data query and printing method;
•Software calibration, password protection function: Pressure and flow of the instrument can be calibrated through keyboard, calibration parameters are password protected;
•Has real-time clock: The instrument can display date and time, convenient for user operation;
•High accuracy, light weight, easy to carry: Novel design, compact structure, easy to carry, high measurement accuracy;
•AC/DC dual use: AC/DC dual use, DC battery can work continuously for more than 4 hours, standby time more than 8 hours.
