IP57 waterproof, applied even under the difficult condition. 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. 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-200Ms/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). --Ability to switch Conductivity, portable TDS meter, Salinity and Resistivity. We could offer all kinds of portable pH meter. For any special type pls feel free to contact us!
