E300 Pro2 Substrate EC/Temperature Meter – More durable, clearer, and even more user-friendly

Take precise substrate electrical conductivity (EC) and temperature measurement to the next level with the AquaMaster Tools E300 Pro2 Substrate EC & Temp Meter a rugged, high-accuracy handheld digital tester designed for growers, horticulturists, agricultural professionals, and anyone needing reliable substrate monitoring. This advanced meter excels in moist substrate and liquid environments such as soil, coconut coir, mats, and nutrient solutions, delivering fast and dependable EC and temperature readings to help you optimise growing conditions and water quality.

The Pro2 upgrade brings improved usability and performance with features like AAA battery power (included), a high-contrast black display with clear white characters, and selectable 1 or 2 decimal precision for finer measurements. A 30-day calibration reminder supports accurate results over time, while the ergonomic rubberised body and robust design ensure durability and comfort during regular use.

What sets the E300 Pro2 apart is its virtually unbreakable EC electrode attached to a 120 cm cord to make substrate access simple and flexible. The electrode is replaceable, extending the life of your meter and lowering long-term costs. With manual EC calibration, you maintain full control over measurement accuracy, and automatic temperature compensation helps ensure precision in varying conditions.

Whether you’re managing substrate nutrient levels, testing water quality in hydroponics, or monitoring conditions in agriculture and food production, this EC & temperature meter gives you the reliable data you need to make informed decisions and achieve healthier growth outcomes.
