The HD 8705 is a combined instrument for taking precise measurements of pH, mV and temperature in the laboratory, on the field and in industrial systems. Various types of electrodes for pH may be connected to the BNC connector electrodes for measuring the oxidoreduction potential (ORP) or ion specific electrodes (ISE). The temperature probes of the TP 870 series are optional (TP 870 for immersion, TP 870C for contact, TP 870A for air, TP 870P for penetration). In pH measurements the temperature probe automatically compensates the electrode temperature coefficient. If the temperature probe is not connected, manual compensation is automatically enabled (with the "up" and "down" keys).
