Bluelab Commercial Truncheon Nutrient Meter - Measures EC, CF, and PPM

No-Calibration EC Meter Built for High-Concentration Nutrient Programs

Standard EC meters can run out of headroom on crops fed at higher-than-typical nutrient concentrations, and the Bluelab Commercial Truncheon is built with an extended range specifically for those programs. It auto-detects liquid the moment it is submerged, with no buttons or switches needed, and displays EC, CF, PPM 500, and PPM 700 simultaneously on bright LED indicators.

The meter is factory calibrated and needs no field calibration, and its fully waterproof, washable construction makes cleaning between reservoirs straightforward for busy commercial operations.

Key Features & Benefits

• Built for high-EC crops — extended measurement range beyond standard truncheon models.
• No calibration required — factory calibrated and ready to use straight out of the box.
• Bright LED indicators — displays EC, CF, PPM 500, and PPM 700 simultaneously for instant reading.
• Auto liquid detection — activates automatically when submerged, no buttons needed.
• Waterproof and fully washable — simple to clean and disinfect between reservoirs.

Who Should Use This

Commercial growers running high-nutrient-concentration crops, or any operation where EC levels regularly exceed a standard truncheon's range, are the direct fit for this meter.

Frequently Asked Questions

How is this different from the standard Truncheon V2?

The Commercial Truncheon is built specifically for high-EC crops, with an extended measurement range that covers nutrient-dense programs beyond the standard Truncheon V2's range. Growers running typical nutrient concentrations are usually well served by the standard model instead.

Does this meter require calibration?

No, it is factory calibrated and requires no field calibration at any point. Simply submerge it in solution for an immediate reading.

How does the auto-detect function work?

The meter automatically detects when it is submerged in liquid and activates the LED display. No buttons or switches are needed to turn it on or off.

Is this meter waterproof?

Yes, it is fully waterproof and can be completely immersed for cleaning and disinfection between reservoirs. This makes it easy to keep hygienic across multiple crop programs.
