How to use
Dip the end of the Truncheon into your mixed nutrient solution and read the strength.
- Check it in conductivity standard regularly. It cannot be calibrated as such, but the standard shows whether it is still reading correctly.
- Clean the sensor at least once a month, or it will under-read.
For pH, pair it with a Bluelab pH Pen. Our pH and EC meters guide explains EC and what strength to aim for.
Questions
Can I calibrate a Bluelab Truncheon?
Not as such. Dipping it in conductivity standard shows whether it is still reading correctly. If it is not, it needs cleaning.
Why is my Truncheon reading low?
It most likely needs cleaning. Clean it at least once a month, or it will under-read.
Does it measure pH?
No. It measures EC, CF and TDS. Use a pH pen alongside it.
