Product Overview	The High Range TDS Meter is a compact portable instrument designed for rapid measurement of total dissolved solids and water temperature in livestock, agricultural and general water-quality applications. Its higher TDS measurement range makes it suitable for water sources containing greater concentrations of dissolved minerals and salts than those typically handled by standard low-range pocket testers. For commercial livestock operations, the meter can be used to inspect wells, storage tanks, treatment systems, drinking-water pipelines and other water sources used in pig farms, poultry houses and cattle facilities. The pocket-sized design allows farm operators, technicians, agricultural engineering companies and water-treatment service teams to perform fast on-site measurements without laboratory equipment.
Key Features	High Range TDS Measurement: Designed for water containing relatively high concentrations of dissolved solids. Integrated Temperature Measurement: Displays water temperature together with TDS measurement information. Automatic Temperature Compensation: Compensates TDS measurements for changes in water temperature within the supported operating range. Graphite Sensing Element: Graphite measurement technology helps reduce oxidation and polarization effects during conductivity-based TDS measurement. Portable Pocket Design: Compact construction is convenient for farm inspections, service work and agricultural project commissioning. Simple Operation: Straightforward button controls support rapid routine measurement and calibration. Water-Resistant Field Construction: Suitable for routine operation around farm water systems and agricultural environments. Digital Display: Provides clear TDS, temperature and instrument-status information for field use.
Structural Components	Handheld Meter Body: Houses the display, electronic processing circuit, operating controls and battery compartment. Graphite TDS Sensor: Measures the electrical characteristics of dissolved ions in water and provides the signal used for TDS calculation. Temperature Sensor: Detects water temperature and supports automatic temperature compensation. Multi-Level Digital Display: Shows TDS values, temperature and operating indicators. Calibration Control: Allows the meter to be calibrated using the appropriate standard solution. Protective Sensor Cap: Protects the sensing area during storage and transportation. Battery Compartment: Provides portable power without requiring an external electrical supply. Optional Accessories: Calibration solutions, carrying cases and maintenance accessories are available upon request.
Working Principle / Structural Principle	The High Range TDS Meter estimates total dissolved solids by measuring the electrical conductivity characteristics of the water sample. Dissolved minerals, salts and other ionic substances allow water to conduct electrical current. When the sensor is immersed in the sample, the instrument measures the conductivity response and converts the measurement into a TDS value using the configured conversion factor. The integrated temperature sensor simultaneously measures water temperature. Automatic temperature compensation adjusts the conductivity-related measurement to reduce the influence of temperature changes on the final TDS reading. The measurement is shown directly on the digital display, allowing operators to quickly compare water conditions at different locations throughout the livestock or agricultural water system.

Measurement Parameters: TDS, EC, temperature and multi-parameter configurations are available upon request. Calibration Package: Calibration solutions and additional maintenance consumables can be supplied according to purchasing requirements. Carrying Package: Protective carrying case and field-testing accessories are available upon request. Water Testing Kit: Can be supplied together with pH, chlorine, conductivity and other water-quality testing equipment according to project requirements. OEM Supply: Packaging and procurement configurations can be customized for distributors and agricultural project purchasers. Project Selection: Equipment can be selected according to local water conditions, livestock species and farm water-management requirements.
Installation & Maintenance	The High Range TDS Meter is a portable instrument and requires no permanent installation. Before use, inspect the sensing area and verify calibration according to the required measurement procedure. Immerse the sensor in a representative water sample to the recommended measurement depth. Allow the reading to stabilize before recording the result. For livestock water systems, measurements can be taken at several locations including the source water, treatment outlet, storage tank and drinking-water distribution point to compare changes throughout the system. After each measurement, rinse the sensing area with clean water to reduce contamination between samples. Mineral deposits and other residues should be removed according to the maintenance procedure. Calibration should be checked periodically, especially when high measurement accuracy is required or when the instrument is used frequently. Store the tester with the protective cap fitted in a clean, dry location.
Project Cases	Commercial Pig Farm Water Inspection: Farm personnel can compare TDS levels between groundwater, storage tanks and drinking-water lines during routine water-system inspections. Poultry Farm Water Management: The tester can be used to monitor changes in dissolved solids across source water and poultry drinking systems. Farm Water Treatment Project: Engineering teams can compare measurements before and after water-treatment equipment to support commissioning and routine inspection. High-Mineral Groundwater Evaluation: The higher measurement range is useful where farm groundwater contains elevated dissolved mineral concentrations. Multi-Farm Technical Service: The portable design allows service teams to carry one tester between multiple livestock and agricultural project sites.
