The hand-held meters from Jumo are ideal for measuring pH, redox potential (ORP) and temperature, or electrolytic conductivity and temperature. The instruments feature a memory for the Min/Max value, and a hold function. To increase the life expectancy of the battery, the instruments can be set so that they switch off automatically within the range from one minute to two hours. The 202710/20 version is an instrument for measuring pH, redox potential (ORP) and temperature. It features both manual and automatic temperature compensation of the measurement. The Pt100 temperature probe necessary for this purpose can be provided as an option. The 202710/30 version is an instrument for measuring electrolytic conductivity and temperature. The pre-assembled conductivity cell incorporates graphite electrodes and has a cell constant of 1.0 cm-1. A temperature probe for automatic temperature compensation is integrated in the measuring cell. The hand-held meter always indicates the conductivity, which is compensated for 25 °C. The 202710/20/070 version also includes calibration solutions and a KCL electrolyte.
