pH Testers Product Description

The PHT-810 pH Testers provide a whole new level of performance in a line of pocket pH testing instrumentation. Featuring advanced technology, the pH testers offer one, two or three point calibration. The PHT-810 pH Testers offer a BNC electrode connector which allows several different pH tester electrode options. The pH testers have an automatic shutoff after two hours of operation to conserve the battery. A small battery symbol that shows the remaining battery charge appears at the top left of the pH tester’s display. pH testers have the ability to store and display the current pH reading on the screen as well as displaying the temperature value in °Celsius or °Fahrenheit. pH tester sampling time can be changed from 1 to 15 seconds.

Calibrating the PHT-810 pH Testers requires pH buffer solutions. The best pH tester calibration is the three point calibration where you use pH 4, 7, and 10 buffers to achieve the best accuracy. However, even a quick one point calibration will help keep your pH testers reading correctly.

NOTE: For the best measurement accuracy, you need to set the temperature of the solution being measured on the pH testers prior to measuring the pH value. You should also calibrate the pH Tester every time the sensor is changed and after every three months of use.
