pH Laboratory Desktop pH MeterDetailed product description：

The PHS-92 laboratory desktop pH meter adopts a blue LCD and dual row digital display, which can simultaneously display the current pH value, time, slope, and temperature value. This instrument is suitable for sampling and measuring the pH value of aqueous solutions in laboratories of colleges, research institutes, environmental monitoring, industrial and mining enterprises, and other departments. Equipped with ORP electrodes, it can measure the ORP (oxidation-reduction potential) value of the solution. It can record measurement values and retrieve historical data that has been recorded at any time; Pressing the CAL key will automatically perform calibration, recognize the standard solution, and return to the measurement state upon completion of calibration. Its notable features include:

A、 One click restore to factory settings, no need to worry about numerical tampering
B、 The large screen displays multiple parameters simultaneously, making all data clear at a glance
C、 LCD screen displays high point, low point, and temperature over limit alarms
D、 Power on self-test and troubleshooting, if there are errors, automatically restore to factory settings
E、 Dedicated watchdog timer, no need to worry about instrument crashes
F、 Key sound feedback, timely prompt that the key press has responded and executed the corresponding operation
