Bluelab Commercial Truncheon Nutrient Meter – Up to 6.0 EC | No Calibration Required
An EC meter built to last a lifetime — now on a bigger scale. The Bluelab Commercial Truncheon Nutrient Meter (SKU: TRUNCOMV2) is the industry-standard nutrient meter scaled up for commercial hydroponic operations and high-strength nutrient solutions. Measuring up to 6.0 EC, 60 CF, 3000 PPM 500, or 4200 PPM 700, it covers the full range needed during intensive growth stages where standard meters fall short.
No calibration. No buttons. No complexity. Simply dip it in and bright LEDs deliver automatic, temperature-compensated readings instantly. Fully waterproof, built to last, and backed by an industry-leading 5-year warranty. Made in New Zealand by Bluelab.

Why EC Measurement Matters in Commercial Growing
All plants need the right amount of nutrients to grow and flourish. Over- or under-feeding wastes expensive nutrient resources and causes plant health issues. Electrical conductivity (EC) measures the total ionic content (dissolved salts) in your solution — the most reliable indicator of nutrient concentration. In commercial operations using high-strength solutions, a standard 0–3.6 EC meter isn’t enough. The Commercial Truncheon’s extended 0–6.0 EC range ensures you always have accurate readings, no matter how intensive your feeding program.
Ideal For
- Commercial hydroponics & large-scale indoor growing
- High-strength nutrient solution management
- Greenhouse & commercial growing operations
- Cannabis cultivation requiring high EC feeding programs
- Coco coir, NFT, DWC & recirculating systems at commercial scale
- Professional cultivators needing extended EC range
