9‑in‑1 Parameter Water Quality Tester

Our handheld 9‑in‑1 Water Quality Tester provides a fast, reliable snapshot of overall water health. It is designed for councils, farms, industry, and environmental managers who need clear, actionable information to guide treatment decisions. By measuring nine key indicators of water quality, this unit helps identify imbalances, diagnose emerging issues, and determine the most effective path to restoring and maintaining a healthy waterbody.

This compact tester delivers laboratory‑style insight in the field, allowing you to assess water clarity, organic load, dissolved solids, salinity, hardness, and general ecosystem condition within seconds.

COD – Chemical Oxygen Demand

COD indicates how much organic material is in the water. High COD means the water contains a lot of decaying matter or pollution, which reduces oxygen levels and stresses aquatic life.

TOC – Total Organic Carbon

TOC measures the amount of carbon‑based material (organic matter) in the water. It helps identify nutrient loads, algae drivers, and contamination sources.

TDS – Total Dissolved Solids

TDS shows how many dissolved minerals, salts, and solids are present. High TDS can affect water clarity, taste, and suitability for irrigation or industrial use.

UV275 – UV Absorbance at 275 nm

This reading shows how much UV light the water absorbs at a specific wavelength. It’s a quick way to detect organic pollutants and algae‑related compounds.

EC – Electrical Conductivity

EC measures how well the water conducts electricity, which increases with dissolved salts and minerals. It’s a simple way to understand salinity and nutrient levels.

Temp – Temperature

Water temperature affects oxygen levels, algae growth, and overall ecosystem balance. It’s essential for interpreting all other parameters and understanding seasonal changes.

SAL – Salinity

Salinity measures the concentration of dissolved salts in the water. It’s important for irrigation, aquatic health, and understanding how freshwater or brackish a waterbody is.

GH – General Hardness

GH indicates the level of calcium and magnesium in the water. It affects aquatic life, plant growth, and how water interacts with soils and infrastructure.

S.G. – Specific Gravity

Specific Gravity shows the density of the water compared to pure water. It helps identify changes caused by dissolved solids, salinity, or contamination. 

Dissolved Oxygen (DO) Meter – High Accuracy Water Quality Tester

This high‑performance Dissolved Oxygen Meter provides fast, accurate measurements of dissolved oxygen, temperature, salinity, and barometric pressure. Designed for aquaculture, environmental monitoring, industrial water checks, and laboratory use, it delivers reliable readings with a large, easy‑to‑read LCD and automatic temperature compensation for precise results in all conditions.

The meter includes stability indication, real‑time data logging, memory storage, and adjustable calibration features. It is ideal for monitoring oxygen levels, assessing water quality, and supporting BOD testing in both field and laboratory environments.
