Guide to Buying Water Quality
Testing Equipment
We offer a wide range of water quality monitoring equipment, suitable for medical, industrial, and wastewater applications. When selecting a water quality testing device, it is important first to identify the intended application—that is, the type of water to be tested—and then determine the specific water quality parameters you need to monitor. Choosing a device designed for your specific purpose can make water quality testing more efficient and effective.
Application Scenarios
Laboratory Water
Tap Water
Industrial Water
Wastewater
An COD、NH3N、TP、TN Analyzer used in wastewater treatment plants, industrial effluent monitoring, and environmental compliance testing to accurately measure COD, ammonia nitrogen, total phosphorus, and total nitrogen.
COD, TP, and (TN measurements usually require a digestion step, whereas NH₃-N can generally be measured directly, except for special or complex water samples.
Digestion
Digestion refers to a pretreatment process carried out prior to analysis, in which chemical reagents (commonly strong acids or strong oxidizing agents) are applied in combination with heating conditions to convert substances in the water sample, including:
complex organic compounds,sparingly soluble or encapsulated inorganic substances, and target analytes bound to particulate matter or colloids,
into simpler, measurable forms (typically ionic species or stable compounds), thereby ensuring the accuracy and reliability of analytical results.
Digester
A Residual Chlorine Analyzer that uses the DPD colorimetric method to accurately measure free and total residual chlorine in water.
A Turbidity Meter is used to measure the turbidity of water. Some turbidity meters can automatically calculate the concentration of insoluble particulate matter based on turbidity measurements.
Some of our turbidity meters are equipped with built-in suspended solids algorithms or calibration curves.
The Online Water Quality Controller needs to be paired with a Online Water Quality Sensor, whereas other Online Water Quality Analyzer come with integrated sensors.
It is divided into online electrode type electrochemical sensor and online optical sensor.
