Bluelab Truncheon Nutrient Meter V2 - 40cm - EC, CF, PPM 500, PPM 700

The Classic No-Calibration EC Meter - All Four Conductivity Scales at a Glance

The Bluelab Truncheon Nutrient Meter V2 is the industry-standard EC meter trusted by hydroponic growers worldwide. All four conductivity scales - EC, CF, PPM 500, and PPM 700 - are displayed simultaneously on a single line of daylight-readable blue LEDs, with no buttons, switches, or calibration required. Simply submerge in your nutrient solution and read. The waterproof construction, removable shroud for easy cleaning, and auto on/off make it as practical as it is reliable.

Key Features & Benefits

Frequently Asked Questions

Does the Truncheon V2 need to be calibrated?

No - the Truncheon is factory-calibrated and requires no field calibration at any point during its service life.

How does the auto on/off work?

The Truncheon automatically detects when it is submerged in liquid and activates the LED display - and turns off when lifted out. No buttons or switches are needed.

What is the maximum EC range?

The Truncheon V2 measures up to 3.6 EC (36 CF, 1800 PPM 500, 2520 PPM 700). For crops requiring higher EC ranges, the Bluelab Commercial Truncheon is recommended.

Can the shroud be removed for cleaning?

Yes - the shroud is removable for thorough cleaning and disinfection, making it easy to maintain hygienic operation between reservoir checks.
