Pen Type EC/TDS Meter AM-P-EC – Aquasol

The Aquasol AM-P-EC is a compact, digital pen-type meter designed for the quick measurement of total dissolved solids (TDS) and electrical conductivity (EC) in water. Ideal for use in both laboratory and field environments, this handheld device offers reliable readings with simple operation and intuitive calibration. It features a protective cap for sensor safety, a clear LCD display, and tactile buttons for power, hold, and calibration functions. The unit runs on two LR44 batteries and is factory-calibrated with a 1413 µS/cm buffer solution, with re-calibration recommended every month for optimal accuracy.

The AM-P-EC model offers a dual-range measurement capability, covering both TDS (0–9990 ppm) and EC (0–9990 µS/cm), with an accuracy of ±2% and a resolution of 1 ppm. The device is lightweight (55 g), and its ergonomic design ensures ease of handling and long-term durability. Maintenance is straightforward—just rinse the electrode after use and avoid direct sunlight or submerging any parts other than the sensor. The meter comes packaged with a standard solution (50 ml) and an instruction manual, making it ready to use right out of the box.
