In plant tissue testing, pH indicates balance of nutrients. Helps identify missing elements.
Calibrate with pH buffer solutions. All of the pH testers here feature 2-point calibration for better accuracy throughout the entire pH scale. You will need to use both pH 7.01 and pH 4.01 calibration solutions to get this accuracy. Calibration solutions are included in some of the meters here, for all others, you will need to order them separately.
The Checker pH pocket tester can provide you with a simple, inexpensive pocket pH tester for about the same cost as a few rolls of pH tape.
The HI 98129 Combo waterproof tester offers high accuracy pH, EC/TDS and temperature measurements in a single tester! No more switching between meters for your routine measurements.
HI 8424N is a microprocessor- based pH meter. HI 8424N can also measure ORP in the mV range using ORP electrodes (available separately).
Compact waterproof pH meter with flat sensor technology requiring just a couple of drops of sample.

The waterproof pHep 4 tester has a dual-level LCD that displays pH and C or F. At startup, pHep performs a self check then displays the remaining battery level to assure proper working condition. (note image is of the pHep5 tester with 0.01 accuracy)
The waterproof pHep 5 tester has a dual-level LCD that displays pH and C or F. At startup, pHep performs a self check then displays the remaining battery level to assure proper working condition.
The pHep pocket tester revolutionized pH measurement by providing everyone with a simple, inexpensive pocket pH tester. The design of these testers also features a larger LCD so measurements are easier to read from any angle.
