The pH/EC/TDS/Temp pen detector measures 0-14 pH, 0-9999 µS/cm EC, 0-9999 ppm TDS, and 0-60°C, with ±0.05 pH and ±2% accuracy, and includes automatic temperature compensation. Calibration involves three-point calibration for pH and single-point calibration for EC and TDS. The tester automatically shuts down after five minutes of inactivity and is powered by four 1.5V LR44 button batteries.

 Tips: How do I calibrate the pH/EC/TDS/Temp Pen Tester?

Calibration is simple and varies depending on the parameter being measured:

• pH Calibration: Use standard buffer solutions (pH 4.00, 7.00, and 10.00). Submerge the probe into the solution, and follow the device’s instructions to calibrate.
• EC/TDS Calibration: Use an EC calibration solution (e.g., 1413 µS/cm), and adjust according to the device’s prompts. The device typically includes easy-to-use buttons for one-touch calibration.
