H600 Pro Handheld Substrate Meter

Unlock Your Pot-tential with H600 Pro Handheld Substrate Meter

Direct substrate testing is a game-changer for South African growers — hard water, uneven moisture, heat stress and organic mixes can hide pH/EC imbalances that cause root rot, nutrient lockout or slow veg growth before symptoms appear. The H600 Pro Handheld Substrate Meter is the professional 5-in-1 tool that measures pH (0.1–14.0), EC (0.0–19.9 mS/cm), TDS (0.0–19.99 PPT), PPM (0–1999 on 700 scale) and temperature (0–50 °C) right in soil, coco, peat or other moist media. User-friendly interface lets you switch parameters instantly, while the built-in calibration indicator reminds you after 30 days to keep readings accurate. 2-point auto pH calibration (4.0 & 7.0) and 1-point auto EC cal make setup fast and reliable, with automatic temperature compensation ensuring consistency across SA’s variable grow temps. IP67 waterproof electrodes handle direct substrate probes or liquid dips, the durable meter comes with a protective carrying case for safe transport between tents or sites, and a 9V battery (included) powers extended sessions. Compatible with Aqua Master substrate electrodes — perfect for deep pot checks, slab testing or liquid reservoirs. Reliable, portable and built for daily use — this meter helps you maintain ideal parameters for stronger roots, better uptake and maximum yields in any medium.
