The most effective way to monitor the performance of your reverse osmosis membrane is through the use of a TDS (or resistivity) meter. If you follow the regular maintenance schedule for your BEV system, the custom rolled RO membrane will typically perform to BEV specifications for 2-3 years and sometimes longer (depending on source water conditions.)

The microprocessor-based Primo series by Hanna® Instruments allow for one touch calibration and automatic compensation for temperature to produce consistent readings over the entire measurement range. Variations in temperature contribute to changes in TDS readings as much as 2% per degree Centigrade. The Primo meters utilize automatic temperature compensation to produce consistent readings at a reference temperature and to ensure TDS readings always reflect the correct concentration.

• High accuracy & exceptional linearity
• Automatic Calibration
• Range: 1–1999 ppm (mg/L)
• Resolution: 1 ppm (mg/L)
• Accuracy: ±2% Full Scale

Designed to work continuously for over 200 hours on 2 common 1.5V batteries, the testers are equipped with Hanna's exclusive BEPS (Battery Error Prevention System) to prevent erroneous readings due to low power. When it is time to change the batteries, a message appears on the LCD.

(The Primo is supplied complete with batteries, calibration solution, and instruction manual.)
