Aqua Master Tools designs and develops measuring instruments in-house in the Netherlands—guided by user feedback and built for reliability, accuracy, and ease of use. The brand is trusted by professional cultivators, greenhouse operators, and serious hobby growers who need consistent pH, EC, and temperature data.
We stock Aqua Master combo pens, handheld meters, substrate testers, multi-parameter controllers, replacement electrodes, and calibration solutions for hydroponic reservoirs, run-to-waste systems, and greenhouse irrigation.
Choose from compact combo pens that read pH and EC in one handheld unit—many with IP67 waterproof housings, automatic temperature compensation, and replaceable electrodes for a longer service life.
Step up to handheld and substrate meters for multi-parameter readings including PPM, TDS, and CF, or dedicated substrate pH and EC probes for coco, rockwool, and soilless mixes. Ideal for daily reservoir checks, nutrient mixing, and troubleshooting drift before it stresses your crop.
For growers who need hands-off stability, Aqua Master C800 Pro controllers continuously monitor and regulate pH, EC, and temperature—keeping nutrient solutions within target ranges around the clock.
Inline and reservoir-mounted options suit recirculating hydro, fertigation skids, and commercial rooms where manual dosing is not practical. Pair with quality calibration solutions and spare electrodes to maintain accuracy season after season.
Accurate readings depend on regular calibration. We stock Aqua Master pH and EC calibration solutions, storage fluids, and replacement electrodes so your meters stay trustworthy.
Follow the manufacturer’s calibration schedule—typically two-point pH and single-point EC checks before each grow cycle or weekly in active reservoirs. Proper care extends electrode life and protects your investment in precision monitoring.
