About Bluelab
Why Bluelab
Made in New Zealand and built to be used every day: the Truncheon has no buttons, no calibration and no batteries to worry about beyond a yearly change, and reads EC, CF and ppm on a scale of lights. The pH Pen is waterproof, calibrates in a minute and shows temperature as well.
Looking after them
Rinse the Truncheon after use; store the pH Pen's probe wet in storage solution and calibrate it every couple of weeks. Solutions are under Nutrient Management.
