PHB-3 portable pH meter is a portable digital pH meter with liquid crystal display. It is very small and can be easily used for testing at the test site. It can be connected to an external pH electrode. PHB-3 portable pH meter uses E201 type composite electrode, which has the advantages of high precision, fast measurement response, good stability, and easy replacement. The measurement accuracy of the PHB-3 portable pH meter is ±0.2pH, and it has a manual temperature compensation function. Since the temperature will cause errors in the pH value measurement results, the manual temperature compensation function of the PHB-3 portable pH meter makes the user's measurement more accurate. . PHB-3 portable pH meter is suitable for on-site testing in experimental sites, assembly lines, sewage treatment and aquaculture.
