◆ Overview
Our factory developed ZDR Series PH recorder solution PH value for high-precision laboratory instruments, and the glass electrode and calomel reference electrode supporting the use of (matching can also be used with the composite electrode). This product is widely used in environmental protection, health care, chemical, pharmaceutical, power plants, food processing, aquaculture and other departments.

Factory production of various types of PH in both figures, high precision, reliable operation and long life equipment in addition to "locate", "Temperature Compensation", also set up "the slope regulation" can also electrode conversion factor to be corrected.

According to actual demand, ZDR Series PH recorder data can be automatically recorded and saved, and can transfer data to computer analysis and processing.
 
◆ PH meter use
1, ambient temperature :0 - 40 ℃
2, relative humidity: ≤ 85%
3, AC power supply: voltage 220V +22 V, frequency 50 +0.55 Hz
4, the measured solution temperature :5-60 ℃
5, supporting electrode: Zero potential is 7PH composite electrode or electrodes 331 and 332 type glass calomel reference electrode.
6, in addition to strong electromagnetic fields without magnetic interference outside.
7, no strong vibration.
◆ the use of the method
1, with random communication cable with the recorder can be more general computer PC586) (connected to the serial port.
2, the computer running Recorder application, set up the recorder records start time, record period, stop time, stop mode and other parameters.
3, set the recorder after the completion of disengagement with the computer, the recorder placed in a test is required of the occasion.
4, after testing, and then connect the recorder and the computer, run the recorder application to record within the data downloaded to a computer data processing.
