  • Fully waterproof
  • Factory calibrated
  • Auto turn on and off

Testing is simple;

Dip the end of the Truncheon into the nutrient solution and wait for a minute or two for the Truncheon's probe to reach the same temperature as the nutrient.

  • Remove the Truncheon from the solution, and then dip back in again to take the reading.
  • The flashing lights along the side represent the value of the solution.
  • It doesn't get any easier.
  • Don't forget to rinse under fresh water after use, and clean once a week.


Handy Hint:  95% of all Truncheons returned as 'Faulty' only require cleaning or new batteries. It's a great idea to buy a cleaning kit which contains everything you need, and check out the cleaning guide to keep your Truncheon in tip top condition.
