high accuracy ph test2012
These meters offer high accuracy, fast response, easy to read displays and long battery life
pHep Meter; pH tester with single point or 2 point calibration
ORP Meter; a low cost, Redox tester that eliminates the need for a special pH meter with mV range
Operating temperature range: 0 to 50 C
Use method
Take off the protective cover.
Use clean water to wash the electrode (around the electrode, there might be some crystalline salt, which is a normal phenomenon. Put the electrode into the clean water, the salt will dissolved away.)
turn on the switch
Put the ORP tester into the liquid which you want to test, till the liquid reaches the lowest immersion line. Some times, the liquid is allowed to over the lowest immersion line.
Gently stir, till the display of the data is stable (usually it need several minutes) when the value beat up or beat down very slow, you can read the data.
Turn off the switch and clean the electrode after use. Use some soft tissue suck water, and then put on the protective cover.
You can drop a few Saturated KCL solutions into the protective to protect the electrode.
