Milwaukee EC45 Pro – EC/TDS Meter for Nutrient Solutions and Fertilisers

EC, TDS and CF metre for hydroponics, fertigation and cultivation

The Milwaukee EC45 Pro is a digital immersion meter for monitoring EC, TDS and CF in nutrient solutions used in hydroponics, soilless cultivation and fertigation. The EC range of up to 6.0 mS/cm allows for rapid verification of nutrient concentration, whilst the 24-LED display enables immediate monitoring directly in tanks and mixing vessels.

Direct reading of nutrient concentration without manual calibration

Calibration is carried out at the factory and requires no adjustment by the user. The instrument switches on automatically when submerged, compensates for temperatures between 5.0 and 50.0°C and switches off 30 seconds after the reading has stabilised. The IP67-rated housing is waterproof and floats; the probe uses a graphite electrode.
