    The Primo series of testers provide a fast and dependable way to measure the total dissolved solids or conductivity in your water samples. It is ideally suited for the rigorous demands of water quality professionals. Many professionals use the cabled version of the Primo 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 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 calibration solution, dip the probe in, and within seconds the meter recognizes the calibration solution and calibrates itself!
