HM Digital Waterproof EC/TDS/Temp Combo Meter
Measures EC, TDS and temperature. It has three different calibration options
(KCl, 442TM, NaCl), each with its own non-linear conversion factor, and
Automatic Temperature Compensation (ATC) using three temperature coefficients.
Measurement Range: 0-9990 uS; 0-8560 ppm (auto ranging).
| 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: | 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. |
