PH Meter, Digital 4 in 1 PH EC TDS Temp Meter for Water Hydroponics, PH and EC PPM Water Tester with ATC for Nutrients Growing, Drinking Water, Home Brewing, Aquaculture, Pool, Aquarium

Product description Different plants and growth stages have varying requirements.

Use a pH EC TDS meter to measure pure water's ppm (above 170 ppm is hard water) and maintain stable EC for proper nutrient delivery.

Balanced pH ensures nutrient absorption.

Always check pH even after reaching appropriate EC levels.

Ever so easy to calibrate How to Calibrate the pH Meter? 1.

Two calibration modes: 6.86/4.00/9.18 and 7.00/10.01 can be chosen to dissolve the chosen powders in different cups with 250ml distilled water.

then stir until the powder has completely dissolved.

2.

Put the electrode into 6.86 solutions, wait for the value to stabilize, and press 'CAL' for 5 seconds and the screen will display 'CAL'.

release the button and wait for 6.86 to flash 3 times to complete 6.86 calibrations.
