This water tester measures both pH and ORP. It has protective IP67-rated housing to guard against water and dust.
This water tester measures both pH and ORP. It has protective IP67-rated housing to guard against water and dust.
The Traceable 4277 pH/ORP Meter makes it easy to monitor water quality. It tests for both pH and ORP using convenient single-handed operation. It's also durably constructed and can store up to 25 data points at a time, so that you can look back and review the water content as you go. NIST-traceable calibration.
