BLUELAB CONDUCTIVITY PEN
£69.99 excl. tax
A compact and robust user-friendly handheld pen which measures the conductivity of nutrient solutions in the units of your choice and temperature in °C or °F. Automatically temperature compensated to ensure accurate readings every time.
Fully waterproof rather than merely water-resistant, the Bluelab Conductivity Pen is designed to float if dropped into a reservoir. Hold function keeps the conductivity reading on screen for as long as required. Easy to calibrate, and calibration check mark reminds the user when recalibration is due. Powered by 1 x AAA alkaline battery (included, 350 hrs life), with power-saving auto shut-down after 4 minutes unused.
