Product Overview	The Portable Water Dissolved Oxygen Meter is a handheld water quality testing instrument designed for rapid measurement of dissolved oxygen in livestock drinking water, farm water tanks, reservoirs, ponds, aquaculture systems and agricultural water supplies. The meter combines a portable digital instrument with an immersion-type dissolved oxygen probe, allowing operators to test water directly at different locations without moving samples to a laboratory. Depending on the selected configuration, dissolved oxygen can be displayed as concentration and oxygen saturation together with water temperature. For commercial livestock and agricultural projects, routine dissolved oxygen testing can support water-quality inspections, source-water evaluation, storage-tank management and troubleshooting of water systems where biological activity or prolonged storage may affect water condition. Optical dissolved oxygen configurations are particularly suitable for field inspection because they can reduce routine probe maintenance and do not require continuous water movement around the sensor during measurement.
Key Features	Portable Field Measurement: Compact handheld construction allows dissolved oxygen testing at water tanks, wells, reservoirs, ponds and livestock facilities. DO and Temperature Display: Selected configurations measure dissolved oxygen and water temperature simultaneously for convenient field inspection. Optical Sensor Option: Optical dissolved oxygen technology is available for stable measurements with reduced routine maintenance. No Continuous Flow Required: Optical configurations can measure without requiring a minimum sample flow, which is useful for tanks, containers and standing water. Automatic Compensation: Temperature compensation is available, while pressure, altitude or salinity compensation can be supplied according to the selected configuration. Clear Digital Display: Large-screen readout supports convenient operation in livestock facilities and outdoor agricultural environments. Data Management Options: Data hold, storage, logging or computer transfer functions are available according to project requirements. Field-Ready Construction: Protective meter housings, rugged probes and carrying cases are available for repeated farm and project use.
Structural Components	Handheld Meter: Contains the digital display, operating keys, signal processing electronics and power supply. Dissolved Oxygen Probe: Immersion sensor used to detect oxygen dissolved in the water sample. Temperature Sensor: Integrated or combined with the DO probe for temperature measurement and compensation. Protective Probe Guard: Helps protect the sensing surface from accidental contact with tank walls, pipes or other solid objects. Probe Cable: Allows the sensor to reach water in tanks, ponds, reservoirs and other field measurement locations. Probe Connector: Provides removable connection between the handheld meter and sensing probe according to model configuration. Protective Carrying Case: Available for organized storage and transportation of the meter, probe and calibration accessories.
Working Principle / Structural Principle	In an optical dissolved oxygen configuration, the probe contains an oxygen-sensitive sensing layer that is excited by a light source. Dissolved oxygen changes the optical response of the sensing material, and the instrument processes this response to calculate the oxygen concentration in the water. Because the optical method does not consume oxygen during measurement, it can provide stable measurements without requiring continuous sample stirring or a minimum flow rate. Optical probes also avoid the electrolyte filling and membrane replacement associated with many traditional electrochemical dissolved oxygen sensors. The integrated temperature sensor measures water temperature and allows the instrument to compensate the dissolved oxygen reading for temperature changes. Pressure, altitude and salinity compensation can also be included according to the selected instrument configuration. The probe is immersed at the required sampling point and allowed to stabilize before the measurement is recorded. Correct probe placement and regular calibration help maintain dependable field results.

Installation & Maintenance	The portable dissolved oxygen meter normally requires no permanent installation. Before measurement, inspect the probe, cable and connector for contamination or physical damage and confirm that the instrument has been calibrated according to the selected operating procedure. Immerse the sensing section completely in the water without allowing the probe to strike the bottom, tank wall, pipework or other hard surfaces. For representative results, select a sampling point that reflects the actual water condition rather than an isolated stagnant corner unless that location is specifically being investigated. Allow the displayed value to stabilize before recording the result. When comparing several livestock houses, tanks or water sources, use a consistent sampling method and similar measurement depth where practical. After testing, rinse the sensing section with suitable clean water to remove sediment, organic matter or chemical residue. Do not scratch or aggressively clean the optical sensing surface. Store the probe according to the requirements of the selected sensor technology. Periodic calibration and sensor-cap inspection should be included in the farm or project maintenance schedule.
Project Cases	Commercial Pig Farm Water Inspection: Farm technicians can compare dissolved oxygen and temperature at the water source, central storage tank and individual livestock-house supply points as part of routine water-quality inspections. Poultry Farm Reservoir Monitoring: Portable testing can be used to inspect raw water stored in farm reservoirs before pumping into drinking-water treatment and distribution systems. Cattle Farm Water Tank Assessment: Dissolved oxygen measurements can support general water-quality investigations where water remains stored for extended periods. Agricultural Engineering Commissioning: Project contractors can perform field measurements at several water-system locations during commissioning or troubleshooting without transporting every sample to an external laboratory. Aquaculture and Farm Pond Monitoring: Operators can carry the meter between different ponds or tanks for rapid dissolved oxygen comparison and routine water management.
