S300 Pro 2 Substrate pH/Temp Meter

The Substrate pH/Temp Meter S300 Pro 2 is the ideal digital hand-held meter for measuring the pH and temperature of any soft, moist substrate, liquid, or substance. It is suitable for various industries, including agriculture, horticulture, and the food industry.

This high-quality and easy-to-use meter is extremely accurate and fits perfectly in the hand, thanks to its rubber ergonomic back. The pH electrode is connected to a 90 cm cord for convenient use. Additionally, it features a 2-point automatic calibration function, simplifying the calibration process. The S300 comes with batteries and includes a replaceable probe to extend the meter's lifespan.

We recommend storing the meter with KCI storage solution in the protective cover.
