The E300 Pro2 Substrate EC/Temperature Meter is the advanced version of a proven digital handheld meter for the precise measurement of EC and temperature in moist substrates and liquids. Developed for professional applications in agriculture, horticulture, hydroponics, and the food sector, the device combines high accuracy with robust construction and improved user-friendliness.

The new Pro2 version has been specifically optimized: instead of button cells, the device operates with practical AAA batteries, while the black display with white readout ensures significantly better readability. Additionally, the display can flexibly show 1 or 2 decimal places.

A special highlight is the nearly unbreakable EC electrode, connected via a 120 cm long cable, allowing for flexible work. The electrode is replaceable, significantly increasing the device's lifespan.

The integrated manual calibration with reminder system supports reliable long-term use. After successful calibration, the display automatically disappears for 30 days and then reminds you of the next calibration.

💡 Ideal for growers, gardeners, and professional users who want to control nutrient values and temperature directly in the substrate.
