What it is
An I2C sensor device that can read any voltage based sensor such as a pH or ORP probe. There are pin headers available to connect a waterproof DS18B20 temperature sensor for temperature compensation. The firmware on the device provides two calibration options, single or dual point which can be used simultaneously.
The board can be purchased by itself, pH and ORP probes, and temperature sensors are also available separately. Buy the board and a probe and get the I2C Sensor Isolator board for 10% off. The discount will be automatically applied.

pH Probe and Calibration Powder
The probe is gel-filled, single-junction, with a plastic body. Calibration powder in pH 4/7/10 that mixes with distilled water for a single use.
A gel-filled, 245 mV potential ORP probe with a platinum disc electrode.
