About the HI-12883 probe
The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0-13 pH, a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged polypropylene body. In addition, to ensure against interference from transient electrical noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated from 0 to 50°C.
Main features:

Simultaneous, pH, EC/TDS and temperature measurements on a large three line LCD display
Selectable temperature unit
pH electrode condition display
mV of pH measurement for electrode check
