shanghai san-凯时娱乐

● the meter is able to recognize up to 12 types of ph standard buffer solutions. there are three options of standard buffer solutions: usa series, nist series and chinese series(ch), there is also customer-defined solution calibration.

● the meter provides two special modes for pure water and pure water mixed with ammonia. these special modes offer temperature compensation for ph value, especially suitable for the electrictiy and petrochemical industries.

2. conductivity measurement features (suited for model sx813, sx823 and sx836)

● 4 calibration points can be chosen, the meter provides calibration guide and automatic checking function.

● the meter is able to switch among conductivity, tds, salinity and resistivity measurement mode. for tds measurement, the coefficient is adjustable.

● the meter is able to recognize up to 8 types conductivity standard solutions. there are two options of standard buffer solutions: usa series and chinese series(ch), there is also customer-defined solution calibration.

● the meter has an automatic range feature with automatic non-linear temperature compensation for pure water and high purity water with conductivity values lower than 10us/cm greatly improving accuracy and suitable for the electricity, microelectronics and pharmaceutical industries.

3. do(dissolved oxygen) measurement features (suited for model sx816, sx825 and sx836)

● do electrode offers a built-in temperature and salinity sensor with automatic temperature comensation and automatic salinity compensation as well as manual barometric pressure compensation. the measurement is more accurate.

● polarographic do electrode with special do calibration cover, electrode polarization only requires 3-5 min, three combined membranes convenient to renew.
