SX700 Series of Waterproof Portable Meters

Product Features

1. Special waterproof connector which four different electrodes (pH, ORP, Conductivity, DO) can be plugged into, ability of the meter to recognize automatically those electrodes.

2. IP57 waterproof, applied even under the difficult conditions.

3. “Mobile Laboratory” – meter, electrode, standard solution and other accessories are all in a portable case.

4. Advanced pH measurement mode

•Automatic calibration, options of three series of pH buffer solution.

•Ability to set two special pH measurement modes of high purity water and ammonia added purity water.

•2503DT pure water pH electrode with a built-in temperature probe, applied in pH measurement of high purity water.

5. The most advanced conductivity measurement mode

•Adopts one common two-ring conductivity electrode (k=1, built-in temperature probe), only one-point calibration, measurement range: 0.5μS/cm~200μS/cm, accuracy≤±1.5%FS.

•Automatic switches of range, automatic non-linear temperature compensation for high purity water.

•DJS-0.1/T conductivity electrode (k=0.1, built-in temperature probe, with a flow tube assembly), applied for measurement of the high purity water<1μS/cm.

•Ability to switch among Conductivity, TDS, Salinity and Resistivity.

6. Advanced dissolved Oxygen measurement mode

•DO500 Dissolved Oxygen electrode can simultaneously measure DO, Conductivity and Temperature to realize automatic salinity compensation for DO measurement.

•Polar gram type DO electrode with special electrode calibration sets, electrode polarization for only 3 to 5 minutes.
