BlueLab Truncheons

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 cleaned and calibrated at least once a month otherwise they'll under-read.

The new MK2 Bluelab "PH Truncheon" meter is currently undergoing testing in NZ before being re-released internationally.

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