BlueLab Truncheon



Sturdy, reliable nutrient meters from Bluelab Hydroponics in New Zealand (formerly NZ Hydroponics).

The Bluelab CF Truncheon measures EC, CF and TDS, is temperature compensated and completely waterproof. These meters tend to go on forever, just make sure they’re checked in Conductivity Standard (see related items below) and cleaned at least once a month otherwise they’ll under-read.

To make caring for these meters easier Bluelab now sell cleaning kits – highly recommended for keeping your meters in the best possible condition.
