Bluelab Combi Meter

The Bluelab Combo Meter is a lightweight, handheld 3-in-1 diagnostic tool engineered to monitor pH, electrical conductivity (EC/CF/PPM), and solution temperature in hydroponic reservoirs, fertigation feeds, and substrate run-off. Combining two dedicated sensors into a single compact device, it delivers fast, accurate readings on the go - ensuring growers can maintain optimal root-zone chemistry to maximise nutrient uptake, prevent deficiencies, and avoid salt burn.

Designed for straightforward operation, the meter features a large, backlit display for high visibility inside grow tents or greenhouses. The included Bluelab pH Probe features simple push-button calibration, while the factory-calibrated conductivity/temperature probe requires zero ongoing calibration adjustments. Together, they provide total environmental clarity across the key parameters that dictate crop health.

Equipped with generous 2-metre probe cables, the Bluelab Combo Meter allows growers to reach deep into large reservoirs or difficult-to-access drainage trays with ease. Customisable display units allow you to view conductivity in EC, CF, PPM 500 (TDS), or PPM 700, and temperature in °C or °F, making it a versatile essential for hobbyists and commercial cultivators alike.

Key Benefits:

• 3-in-1 Portable Testing: Measures solution pH, conductivity, and temperature in one compact, battery-powered handheld unit.

• Factory-Calibrated Conductivity Probe: Requires no ongoing calibration adjustments for conductivity and temperature testing.

• Simple Push-Button pH Calibration: Easy two-point calibration routine with clear on-screen indicators.

• Backlit LCD Screen: Delivers clear, highly visible digital readouts across low-light grow room environments.

• Generous 2-Metre Probe Cables: Extended cable reach facilitates easy testing in deep reservoirs, tall mixing tanks, and run-off trays.

• Customisable Measurement Units: Toggle conductivity between EC, CF, PPM 500 (TDS), or PPM 700, and temperature between °C and °F.
