Essentials pH Meter Convenient and easy-to-use meters specially designed for testing the pH & CF/ EC level of nutrient solutions. Just dip the sensor into test solution, stir and wait, then read a stable reading in about 20 seconds. The Essentials pH & CF/EC meters, are truly the most rugged glass type pH & CF/EC testers around. They are drop-shock resistant, temperature compensating and easy to calibrate. The units are also water resistant, allowing easy washing. Even if the meter is accidentally dropped into the water, it will remain afloat so as to enable immediate retrieval without damaging the electronics. The meters cost less per sample than competing high quality testers. Meters have about 1-3 year lifespan depending on rate of sampling. (Units are good for a minimum of 365 accurate pH tests).

Bluelab Truncheon Nutrient Meter

The World’s favorite conductivity meter. Simply brilliant, brilliantly simple!

It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate.

Understanding the conductivity of the nutrient solution takes the guesswork out of feeding plants. It will also save you money! Using the Bluelab Truncheon® Nutrient Meter is the fastest and easiest way to measure the conductivity!

To take a reading of your solution - simply place the probe head into the solution and the reading is indicated by the flashing lights. Calibration of the Truncheon® Nutrient Meter is not required.

The Bluelab French-English Truncheon® Nutrient Meter is available with Canadian-French / English labels and instructions.

Meter length: 40.7cm or 16 1/32 in.
