Comprehensive 5-in-1 Water Quality Analysis with High Accuracy
Measures five key parameters—pH, dissolved oxygen (DO), ammonia nitrogen (NH3-N), nitrite (NO2), and temperature—with high accuracy using spectrophotometric technology.
5 in 1 Water Quality Tester for pH, DO, Ammonia and Nitrite
Description
It displays multiple water parameters on one screen, reducing the need to carry separate single-parameter meters.
These readings do not detect bacteria, heavy metals or many other contaminants that require dedicated laboratory analysis, so they do not determine whether water is safe to drink.

Q & A
Can it tell me if my tap water is safe to drink?
No. It gives specific readings only. Bacteria, heavy metals and many other contaminants require laboratory testing.
Why is pH Important in Water Quality Testing?
pH is a key indicator of water quality. It affects the solubility and availability of various chemicals and nutrients in water, which can impact aquatic life and human health.
What is the Ideal pH Range for Drinking Water?
The ideal pH for drinking water ranges from 6.5 to 8.5, as recommended by health standards.
How Do I Use a pH Meter to Test Water?
Simply calibrate your pH meter and insert the electrode into the water sample. Ensure the electrode is fully submerged for an accurate reading.
How Do I Maintain My pH Meter for Water Testing?
Rinse the probe with distilled water after each use, store it with a pH electrode solution, and calibrate regularly.
How Often Should I Test My Water's pH?
For drinking water or aquariums, test weekly or whenever water quality issues arise. For industrial use, follow specific testing protocols.
