1. Special waterproof connector which four different electrodes(pH, ORP, Conductivity, TDS, and Temperature ) can be plugged into and automatically recognized.
2. Waterproof, applied even under very difficult conditions.
3. Ability to set two special pH measurement models of high-purity water and ammonia-added purity water.
4. Adopts one common two-ring conductivity electrode(k=1), only one point calibration.
5. Automatic switches of range, and automatic non-linear temperature compensation for high-purity water.
6. Ability to switch among Conductivity, TDS, Salinity, and sensitivity.
