Special water-proof connector which four different electrodes (pH, ORP. Conductivity, DO) can be plugged into, ability of the meter to recognize automatically those electrodes.
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.
IP57 water-proof, applied even under the difficult conditions.
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: 0.54S/cm-200mS/cm, accuracy: less than 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 less than 14S/cm. Ability to switch among Conductivity, TDS, Salinity and Resistivity.
Mobile Laboratory
– meter, electrode, standard solution and other accessories are all in a portablecase.
Advanced Dissolved Oxygen measurement mode
DO 500 Dissolved Oxygen electrode can simultaneously measure DO, Conductivity and Temperature to realize automatic salinity compensation for DO measurement. Polarogram type DO electrode with special electrode calibration sets, electrode polarization for only 3 to 5 minutes.
