ZRN-PH-D-based desktop pH | meter
 

Product description:

ZRN-PH-D-type laboratory bench pH meter, which uses blue LCD, double digital display, can display the current pH value, time, slope, temperature. The instrument applies to universities, research institutes, environmental laboratory monitoring, industrial and mining enterprises and other sectors of sample to measure pH of the aqueous solution, coupled with a measurable solution ORP electrode ORP (oxidation - reduction potential) The value of the measured values ​​can be recorded, and can always look up once recorded historical data ; Pressing CAL automatically calibrates, automatic identification standards, calibration is complete the automatic return to measuring the state of its salient features are:
A, a key to restore to factory settings, without worrying about the value adjustment disorder
B, large-screen display multiple parameters simultaneously, all data at a glance
C, LCD display highs, lows, temperature gauge warning
D, POST troubleshooting, if wrong, automatically restore factory settings
E, dedicated watchdog timer, without worrying about the instrument crash
F, button audio feedback, timely tips button press has responded and perform the appropriate action
