Multi-Parameter pH Pen, EC/TDS/Temperature Options

Choose the combination of water readings needed for a sample-testing routine. This digital pen range offers pH with conductivity, dissolved solids or both. It is for aquarium, hydroponic and suitable laboratory checks.

• ✅ Choose the parameters you need — Three versions offer different EC and TDS combinations.
• ✅ Read a numerical result — The digital display avoids comparing a strip chart.
• ✅ Keep temperature in context — Each selection includes a temperature function.
• ✅ Prepare repeat checks — Calibration controls let you use suitable reference solutions.

Choose the functions as well as the pen

PH EC TEMP measures pH, conductivity and temperature; PH TDS TEMP replaces conductivity with TDS. PH EC TDS TEMP includes all four functions.

Calibrate and clean the electrode according to the selected model's instructions. Three LR44 cells are required and not included; these readings alone do not establish drinking-water safety.
