Introduction
Product Definition
The A51 water quality testing pen (product ID: a51-water-quality-test-pen) is a portable water purity testing tool used to measure the total dissolved solids (TDS) in water, with results displayed in ppm. It is suitable for testing water purity in household tap water, well water, mountain spring water, drinking water, purified water from water purifiers, and water treatment industry applications.
Product Features
- Portable design with a compact form factor, easy to carry and use for on-site testing.
- Three-digit display that shows TDS readings directly for quick and clear results.
- Measuring range of 0-999ppm, sufficient for daily water purity testing needs.
- Accuracy within ±2%, providing reliable reference results.
- Equipped with a power key for simple operation and easy on/off control.
- Equipped with a hold key to lock the current reading for convenient recording and comparison.
- Probe-type sensor detection; the immersion depth of the pen must not exceed the sensor height.

FAQ
Q: What can the A51 water quality testing pen detect?
A: The A51 water quality testing pen measures water purity (TDS value), with a measuring range of 0-999ppm and an accuracy of ±2%.
Q: Can the A51 water quality testing pen determine whether water is good or bad?
A: No. This testing pen can only measure water purity; it cannot determine whether water is good or bad.
Q: What types of water can the A51 water quality testing pen test?
A: It is suitable for water treatment industry use, household tap water, well water, mountain spring water, drinking water, and purified water from water purifiers (RO reverse osmosis purifiers, ultrafiltration purifiers, functional water purifiers), etc.
Q: What battery does the A51 water quality testing pen use?
A: It uses 2 LR44 button cells.
Q: What should be noted when immersing the pen in water for measurement?
A: The immersion depth of the pen must not exceed the sensor height.
Q: What is the difference in TDS value between RO reverse osmosis purifiers and ultrafiltration purifiers?
A: According to product information, RO reverse osmosis purifiers can remove over 95% of TDS; ultrafiltration purifiers remove very little TDS.
