Combo pH/EC/TDS/C/PPM Tester

This waterproof tester offers high accuracy pH, EC/TDS, and temperature measurements all in a single tester! No more switching between meters for your routine measurements. This floating, waterproof combination tester has an easy to read LCD and an automatic shut-off. pH and EC/TDS readings are automatically temperature compensated.

This tester features a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode. The extendable cloth junction provides an extended electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted.

The EC/TDS conversion factor is user-selectable as well as the temperature compensation coefficient (β).

Fast, efficient, accurate and portable, the combo pH, EC/TDS, and temperature tester combines all the features users have requested and more!

Q:	Why are PPM, TDS, pH and EC important?
A:	PPM and TDS are abbreviations that represent the concentration of elements in a solution or atmosphere. PPM is short for parts per million and TDS for total dissolved solids. EC (electro conductivity) is another form of measurement for TDS. PH is a measure of acidity or alkalinity which dictates plant uptake of particular elements.

Q:	My pH meter doesn't hold calibration. How often should I recalibrate it?
A:	pH meters do need to be calibrated by the user every day since the membrane does change and is affected by the temperature as well. If pH values are very critical then it will need to be recalibrated several times a day, or before each sample test (depending on how critical the value is). Uncontaminated calibration solution is very important as well. For each calibration, pour some solution in a separate container. Keep out of sunlight and away from heat.

Q:	What is the suggested pH range for my hydroponic system and soil plants?
A:	Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
