Product Overview	The Portable Multi-Parameter Water Quality Meter is a compact field testing instrument designed to combine pH, electrical conductivity (EC) and total dissolved solids (TDS) measurement in one portable unit. A combination probe simplifies routine inspection by reducing the need to carry separate meters and electrodes. The meter is suitable for livestock drinking water inspection, farm water storage systems, water treatment rooms, agricultural water sources and other locations requiring rapid on-site water quality checks. Its portable, battery-powered structure is particularly useful for technicians working across multiple livestock houses or project sites. For commercial livestock equipment projects, pig farm construction and steel structure building applications, the instrument can be used as part of routine commissioning, water supply inspection and preventive maintenance procedures.
Key Features	Three water quality functions in one portable meter: pH, EC and TDS. Combination probe simplifies field measurement and reduces separate sensor handling. Automatic temperature compensation supports more consistent EC and TDS measurements across changing water temperatures. Large digital display for convenient reading during routine farm inspections. Manual single-point calibration provides straightforward field maintenance. Replaceable probe design supports long-term servicing and routine maintenance. Battery-powered operation is suitable for livestock houses, water tanks and remote sampling points. Compact handheld construction makes the meter easy to transport between different farm areas. Suitable for commercial farms, agricultural projects, water treatment systems and environmental testing.
Structural Components	Handheld Meter Body: Contains the measuring electronics, display, adjustment controls and battery compartment. Combination Probe: Integrates pH, EC and TDS sensing functions into one probe assembly. pH Sensor: Measures the acidity or alkalinity of the water sample. Conductivity Sensor: Measures the ability of dissolved ions in water to conduct electricity. TDS Measurement Circuit: Converts conductivity data into an estimated total dissolved solids value using the configured conversion factor. Temperature Compensation System: Automatically compensates conductivity-related measurements for temperature variation. Probe Cable: Provides convenient access to tanks, troughs, reservoirs and sampling containers. Protective Probe Cap: Helps protect the sensor during transportation and storage.
Working Principle	The instrument measures several important water quality indicators through a combination probe. The pH sensor measures the electrochemical potential associated with hydrogen ion activity and converts the signal into a pH value. The conductivity section measures electrical conductivity generated by dissolved ionic substances in the water. TDS is calculated from conductivity using an established conversion factor. Automatic temperature compensation adjusts conductivity-related readings for changes in sample temperature. Before routine testing, the appropriate measuring range should be selected and the instrument calibrated using suitable standard solutions.

Calibration and maintenance consumable packages: According to project requirements. Combined farm water testing solutions: Available upon request. Testing equipment packages for livestock equipment and pig farm construction projects: Designed according to local climate and farm conditions.
Installation & Maintenance	The portable meter does not require permanent installation. Connect the combination probe, install the battery and calibrate the instrument with appropriate standard solutions before testing. Place the sensor into a representative water sample and gently move or stir the probe to obtain a stable reading. Rinse the probe between different samples to reduce cross-contamination. The pH sensing section should be kept hydrated with an appropriate electrode storage solution when not in use. Distilled or deionized water should not be used for long-term storage of the pH electrode. Residue on conductivity sensors can affect EC and TDS measurement, so routine cleaning is recommended. Calibration should also be performed after cleaning, extended storage, probe replacement or whenever measurement accuracy needs to be verified.
Product FAQ	What water quality parameters can this meter measure? The reference configuration measures pH, electrical conductivity and total dissolved solids using one combination probe. Why are pH, EC and TDS useful in livestock water management? These measurements help farm operators evaluate acidity or alkalinity and monitor changes in dissolved ionic content in drinking water, storage tanks and treatment systems. Can the meter be used directly on a livestock farm? Yes. Its portable, battery-powered design is suitable for field sampling at tanks, reservoirs, water treatment rooms and other farm water monitoring points. Does it require permanent installation? No. It is a handheld testing instrument intended for portable inspection and routine sampling. How should the probe be maintained? Rinse the probe after testing, clean deposits when necessary, store the pH sensor in suitable storage solution and calibrate regularly using appropriate standards.
