Portable Free Chlorine Measurement Meter

Portable residual chlorine meters use either the electrode method or the colorimetric method to detect the free chlorine content in water. The electrode method measures the current signal generated by chlorine ions through an electrochemical sensor, while the colorimetric method determines absorbance after DPD reagent reacts with residual chlorine to produce color. These devices are used for on-site rapid testing in places such as water treatment plants, swimming pools, and food processing facilities to ensure water quality meets usage standards.
Selection
When selecting, ensure the measurement range covers the usage scenarios and the accuracy meets testing requirements. Check the instrument's protection rating to suit the on-site environment, and consider the convenience of obtaining reagents and consumables. Verify the calibration methods and data storage functions, and compare the response times and operational complexity of different models. Confirm that the battery life and maintenance cycle align with the frequency of use.

Handheld viscosity cups are used for rapid assessment of paint viscosity at construction sites.
A handheld viscosity cup is a portable tool used to quickly assess the viscosity of coatings at construction sites. It operates based on the flow-out time method, calculating viscosity by measuring the time it takes for the coating to flow out of the cup's orifice. It is suitable for Newtonian or approximately Newtonian fluids.
