3) PH60F-Z Flat probe testers are mostly for flat surface sample test.
a)
For skin test: skin should be without sweat or dirt, nor be overly cleaned (do not use facewash
products before testing) to avoid affecting measurement results, dampen skin with some distilled
water, slightly force flat probe onto the skin, get readings after value stabilized.
b)
For paper, fabric and leather test: add a few drops of distilled/deionized water on surface before
performing tests.
c)
For micro sample testing, use a container with an inner diameter<=19mm and a flat bottom. The
tester can test volume >=0.5ml.
8 ORP Measurement
ORP stands for Oxidation-
Reduction Potential, measured in mV. It’s also called redox. ORP
is a
measure of the cleanliness of water & its ability to break down contaminants. A separate ORP
probe (ORP60-DA) needs to be installed to be able to measure ORP.
Power on the PH60-Z tester, unscrew the original probe, and install the ORP60-DA probe, then the
tester will automatically switch to ORP measurement mode (Refer to Section 14 for how to replace
a probe).
Rinse the probe in distilled water and dry it. Dip the probe in sample solution, shake for a few
seconds, and allow it to stand still. Get the ORP readings after
appears and stays on screen.
