Hanna Instruments PRIMO3 Pocket TDS/Temperature Tester (0 to 1999ppm)
This pocket total dissolved solids (TDS), tester measures both TDS and temperature using a remote probe fitted with a 1m cable.
The pocket sized PRIMO3 tester provides a fast and dependable way to measure the total dissolved solids in water samples.
The PRIMO3 is ideally suited to the rigorous demands of water quality professionals who will appreciate the practicality of the clear, easy to read LCD for 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 3 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 3 automatically enters calibration mode. Simply open a sachet of calibration solution, dip the probe in, and within seconds the meter recognises the calibration solution and calibrates itself!
