ESSENTIALS Professional Digital pH & EC Meters

The Essentials pH Pro & EC Pro meters are professional quality, reliable and available with replacement probes.

They have a large screen to view results and are very easy to use. They have screw calibration and come with a built-in small screwdriver. The meters have a lifespan of about 1 to 3 years depending on rate of sampling. (Units are good for 365 accurate tests.)

They are fully waterproof and drop proof, making these some of the most robust meters on the market! Probes are replaceable so when your pH probe starts to go and your readings become erratic, don't go to the expense of buying a new meter, simply buy a replacement probe!
