Product Overview	The Free Chlorine Drinking Water Tester is a portable digital colorimeter designed for routine measurement of free chlorine residual in livestock and agricultural drinking water systems. It provides farm managers, livestock technicians, equipment contractors and water-treatment personnel with a convenient method for checking chlorination performance at different points throughout the water distribution network. Typical sampling locations include the incoming water supply, storage tanks, chemical dosing outlets, livestock-house inlets and drinking line endpoints. Digital colorimetric measurement reduces dependence on subjective visual color comparison and provides a direct numerical result for routine water-management records. The tester is suitable for poultry farms, pig farms, cattle facilities, breeding farms and agricultural engineering projects using chlorinated drinking water. Its compact field design makes it especially useful for commercial farms where several buildings or drinking water lines must be inspected regularly.
Key Features	Digital Free Chlorine Measurement: Displays chlorine concentration directly for convenient routine water-quality inspection. DPD Colorimetric Testing: Uses a widely applied colorimetric method for determining free chlorine in drinking water. Portable Field Operation: Compact construction allows technicians to move easily between livestock houses, water rooms and dosing stations. Fast Routine Inspection: Suitable for frequent checks during daily drinking water sanitation and farm biosecurity management. Multiple Sampling Locations: Can be used to compare chlorine residual at the water source, storage system, dosing outlet, building inlet and drinking line endpoint. Direct Numerical Reading: Helps reduce uncertainty associated with manually comparing sample colors against visual reference charts. Battery-Powered Design: Suitable for field testing where a mains electrical supply may not be available. Commercial Farm Application: Suitable for poultry, pig, cattle and integrated livestock engineering projects.
Structural Components	Portable Meter Body: Houses the optical system, electronics, controls and power supply in a compact handheld enclosure. Digital Display: Provides a direct numerical chlorine concentration reading after the measurement cycle. Optical Measurement Chamber: Holds the sample cuvette in a consistent position during colorimetric analysis. Light Source: Provides controlled illumination through the reacted water sample according to the selected instrument configuration. Optical Detector: Measures transmitted light and allows the instrument to calculate chlorine concentration. Sample Cuvettes: Reusable transparent cells hold the water sample during blanking and final measurement. DPD Reagents: Appropriate free chlorine reagents are used to develop the measurable color reaction. Battery Compartment: Supports portable operation without permanent electrical connection. Optional Carrying Case: Available upon request for organized transport of the tester, sample cells, reagents and accessories.
Working Principle / Structural Principle	The tester operates using a colorimetric measurement principle. A clean drinking water sample is placed into the sample cuvette and used to establish the optical reference according to the instrument operating procedure. The specified DPD reagent is then added to the water sample. Free chlorine reacts with the reagent and develops a pink color. The intensity of this color varies with the concentration of free chlorine present in the sample. The reacted sample is placed in the optical chamber, where the instrument passes light through the solution. The optical detector measures the transmitted light and the electronic circuit converts the response into a free chlorine concentration displayed on the screen. For consistent results, the sample cell should be clean and free from fingerprints, external water droplets, scratches or residue that could interfere with the optical measurement. Testing procedures and reaction times should follow the instructions supplied with the selected reagent and instrument.

Project Supply: Testing equipment packages can be prepared according to local water conditions, farm size and livestock drinking system design.
Installation & Maintenance	The Free Chlorine Drinking Water Tester is a portable instrument and normally does not require permanent installation. It can be carried between water treatment rooms, livestock houses and drinking line sampling points. Before each test, use a clean sample cuvette and collect a representative fresh water sample. Rinse the cuvette according to the instrument procedure and ensure the outside surface is clean before placing it into the optical chamber. Fingerprints, water droplets, scratches and contamination on the optical surface of the cuvette may affect measurement consistency. Wipe the cuvette with a clean lint-free cloth before measurement. Use only compatible reagents and follow the required reagent dosage, mixing method and reaction time. Chlorine samples should be tested promptly because disinfectant residual can change after sampling. After testing, rinse reusable sample cells thoroughly with clean water. Do not use abrasive materials that could scratch optical surfaces. Store the instrument, cuvettes and reagents in clean and dry conditions. Replace expired or contaminated reagents and inspect batteries periodically. Calibration verification can be carried out with compatible standards according to farm quality-control requirements.
Project Cases	Commercial Broiler Farm Water Monitoring: A portable tester can be used to compare free chlorine measurements at the central dosing station, individual poultry house inlets and the far ends of nipple drinking lines. Pig Farm Water Treatment Upgrade: Farm technicians can use routine chlorine testing to evaluate drinking water conditions before and after adjustments to chemical dosing equipment. New Poultry House Commissioning: Free chlorine measurements can form part of drinking water system inspection when new storage tanks, dosing pumps, regulators and nipple lines are placed into operation. Multi-House Livestock Complex: One or more portable testers can be included in the maintenance equipment package for routine inspection across several production buildings. Waterline Sanitation Program: Testing at different points in the distribution network can help personnel evaluate whether the intended disinfectant residual reaches the downstream drinking equipment.
