Pocket Water Quality Tester

The NShi 4 in 1 Digital pH EC Meter measures pH, EC, TDS and temperature in a single red ABS pen. It targets hydroponic growers, aquarium keepers and anyone who needs rapid water-quality checks without laboratory equipment. The 0–14 pH range with 0.01 resolution and 0–9990 ppm span covers typical nutrient solutions and tank water.

Automatic Calibration and Compensation

A three-point calibration routine aligns the glass electrode to pH 4.00, 6.86 and 9.18 reference solutions, removing manual guesswork. Automatic temperature compensation adjusts readings across 0 °C–60 °C (32 °F–140 °F) so changing liquid temperature does not skew results. The high-sensitivity probe and algorithm chip deliver stable values within seconds.

Probe and Scale Limits

The glass bulb is fragile and must stay moist; dry storage or impact can ruin accuracy. The 0–9990 ppm ceiling means very concentrated brines or industrial effluents fall outside the readable range. Users needing data logging, PC connectivity or replaceable electrode modules will find this pen lacks those features.

Questions about this item

How often will the glass probe need replacing?

The high-sensitivity glass probe is a consumable part; plan to replace it when calibration drifts or response slows, typically after months of daily hydroponic use.

What measurement ceiling stops the EC/TDS reading first?

The tester tops out at 9990 ppm, so nutrient solutions above that level will read at the maximum instead of their true value.

Does the meter heat up or make noise during continuous monitoring?

No moving parts or active cooling are present; the LCD tester draws minimal power and stays silent and cool even during all-day operation.
