Bluelab Commercial Truncheon Nutrient Meter | High-Range 6.0 EC

The Bluelab Commercial Truncheon Nutrient Meter is a waterproof conductivity meter for checking the strength of hydroponic nutrient solutions. Its extended scale reads from 0.2 to 6.0 EC, making it suitable for reservoirs and stronger solutions that exceed the range of the standard Bluelab Truncheon.

Simply place the probe in the solution. The meter detects the liquid automatically and illuminates LEDs beside the reading. Its long design also makes it practical for checking and mixing nutrient reservoirs.

Key features

• Measures nutrient solution strength across EC, CF, ppm 500 (TDS) and ppm 700 scales.
• Extended measuring range of 0.2–6.0 EC.
• Waterproof construction for routine reservoir checks.
• Automatic liquid detection and illuminated readings, with no buttons to operate.
• No calibration required.

How to use

Place the measuring end into the nutrient solution and read the illuminated value on the relevant scale. Rinse and clean the probe in accordance with Bluelab’s care instructions after use. Do not use or store the meter outside its stated 0–50°C operating range.

Choosing the right Truncheon

The Commercial Truncheon measures up to 6.0 EC. Bluelab also offers a standard Truncheon with a lower maximum of 3.6 EC. Choose the measuring range that suits the solutions being checked.
