Test Kits & Equipment » TDS Meter

The Primo TDS tester provides a fast and dependable way to measure the Total Dissolved Solids in your water samples. It is ideally suited for the rigorous demands of water quality professionals, who will appreciate the practicality of Primo's easy-to-read LCD when demonstrating the before and after results of conditioning and filtration systems. Temperature is compensated automatically to ensure the readings are consistent to the standard or reference temperature.

Operating and routine maintenance has never been easier. Primo TDS uses a single button at the top of the meter. Press it once and the meter is powered and ready for use. Press and hold the button for a few seconds and Primo automatically enters calibration mode. Simply open a sachet of the calibration solution, dip the probe and within seconds the meter recognizes the calibration solution and calibrates itself! Maximum battery life is managed by Primo's power microprocessor, which automatically turns it of after 5 minutes.

• Displays TDS levels of the feed water and product water with in & out electrode probes.
• Highly efficient and accurate due to its advanced microprocessor technology.
• Auto-Off function conserves battery power. The unit shuts off automatically after 10 minutes of non-use.
• Dual Range 0-9990 ppm.
• Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
• Comes equipped with Mur-lok® Quick-Connect T-fittings.
• Installs quickly and easily.
• One year warranty.

For optimal performance, re-calibrate your meters periodically or if testing TDS or conductivity levels in wide or different ranges.

• NaCl calibration solution.
• Comes in lightweight HDPE plastic bottles.
• Sealed with a coated foam liner.

• Measures electrical conductivity (EC), total dissolved solids (TDS) and temperature.
• Three different calibration options (KCl, 442TM, NaCl), each with its own non-linear conversion factor.
• Automatic Temperature Compensation (ATC) using three temperature coefficients.
• Waterproof housing.
• Measurement Range: 0-9990 µS; 0-8560 ppm (auto-ranging).
• Digital Calibration (push button).
• Auto-off function, data-hold function and low-battery indicator.
• Display: large and easy-to-read LCD screen includes simultaneous temperature reading.
• Factory Calibrated: The COM-100 meter is calibrated with a 1413 µS solution. The meter can be recalibrated with digital calibration using the push buttons, rather than a screwdriver. Includes a cap, batteries and lanyard.
• One year warranty.
