Product Overview	The Portable Water EC/TDS Meter is a handheld low-range water quality instrument for measuring electrical conductivity (EC), total dissolved solids (TDS) and temperature. Its compact construction and separate probe make it practical for field testing at livestock farms, agricultural water systems and engineering sites. The meter is particularly suitable for low ionic-strength water applications. In commercial pig farms, it can be used for comparative inspection of source water, treated water, storage tanks and livestock drinking-water distribution points. The rugged housing and portable probe configuration also support routine maintenance and commissioning work.
Key Features	• Low-range EC measurement from 0 to 3999 μS/cm. • TDS measurement from 0 to 2000 ppm. • Integrated temperature measurement with automatic temperature compensation. • Rugged IP67-rated meter housing for demanding field environments. • Replaceable EC/TDS probe for easier long-term service. • Two-ring conductivity probe designed for low-range EC and TDS testing. • Quick-connect DIN probe connection for convenient installation and removal. • Multi-level LCD display provides EC/TDS and temperature information. • Automatic one-point EC/TDS calibration simplifies routine testing. • Selectable TDS conversion factor supports different testing requirements. • Low-battery indication and configurable automatic shut-off support field operation.
Structural Components	The instrument consists of a rugged handheld meter body, LCD display, operating buttons, battery compartment, external EC/TDS probe and connecting cable. The supplied probe combines EC/TDS sensing with a built-in temperature sensor. The two-ring conductivity design is intended for low-range measurements, while the replaceable probe structure facilitates servicing and component replacement. A Quick Connect DIN interface provides a secure connection between the meter and probe. The cable connection is designed for convenient attachment and removal during inspection, transportation and maintenance.
Working Principle / Structural Principle	EC measurement is based on the electrical conductivity of the water sample. The conductivity probe detects the electrical response of the solution and the meter converts this response into an EC reading. TDS is derived from the measured conductivity using a selectable conversion factor. The conversion factor can be adjusted according to the characteristics of the water and the testing application. The integrated temperature sensor measures sample temperature while the meter automatically compensates EC/TDS readings for temperature effects. This helps provide more consistent measurements when water temperature varies.

Installation & Maintenance	No fixed installation is required. Connect the probe through the DIN interface, rinse the sensing end and immerse the probe into a representative water sample. Keep the sensing area sufficiently clear of the container wall and bottom during measurement. Before routine operation, calibrate the EC/TDS function with a suitable conductivity standard according to the selected testing range. Allow the reading to stabilize before recording results. Rinse the probe with clean or deionized water between samples to minimize cross-contamination. Keep the sensing area clean and inspect the cable and connector regularly. Replace the electrode when its measurement performance no longer meets project requirements. Store the meter and probe according to the applicable manufacturer's maintenance instructions and protect the equipment from unnecessary mechanical impact during transportation.
Project Cases	The meter can be incorporated into water quality inspection procedures for commercial pig farm construction, livestock facility upgrades and agricultural water system commissioning. Typical project deployment includes comparative testing at groundwater or municipal supply points, water treatment outlets, storage tanks, building inlets and livestock drinking-line endpoints. This provides engineering teams with practical EC and TDS data during commissioning and routine maintenance. For multi-house livestock facilities and integrated farming projects, multiple meters, replacement probes and calibration accessories can be supplied according to project requirements.
