Works well, very pleased with it.
This allows me to know when to change out the filters on our Reverse Osmosis system.

INACCURATE - READINGS CHANGE AGAINST SAME REFERENCE STD.
The order consisted of three TDS Meters, with the hope of keeping two devices. Meters were tested against Reference Standards; two calibrated and verified Thermometers reading 72.3°F & 72.4°F and TDS Solution 166 ppm. Meters being tested were acclimated to their environment for thirty (30) minutes with Protective Cap removed. Meters were then triple rinsed in 000 ppm solution and allowed to air dry. Three readings were taken five (5) minutes a part. Each set of readings were greater than specifications; therefore the middle readings for ppm was used, with its corresponding temperature readings. Readings were:Yellow – 139 ppm / 66.3°FWhite – 153 ppm / 70.8°FTeal – 191 ppm / 70.3°FAll TDS Meters are being returned for refund.DO NOT RECCOMEND.
