Built in temperature sensor with four ring platinum EC-TDS electrodes

HI 76303 is a digital conductivity electrode with a built-in temperature sensor; Using a four ring probe with platinum sensors, multiple range measurements can be completed with just one electrode.
The four ring potential measurement system can measure multiple samples while minimizing polarization effects; Two outer loops apply AC voltage and induce a current loop in the solution, while two inner loops measure the voltage drop caused by the current loop.
This allows for a reading range from very high to very low without changing the electrode. HI 76303 uses chemically resistant plastic sleeves to maintain control over external interference of the sample.
Due to temperature being an important factor in measuring conductivity, built-in temperature sensors are very useful; No external temperature probe is required, so measurements can be easily taken.
