Details
The pNa is an easy-to-use and inexpensive water quality tester for determining water hardness/softness. The hardness of water is due to the presence of magnesium and calcium. These make washing difficult, waste soap and create unpleasant scum and scale deposits. With a zeolite system, the calcium and magnesium ions are substituted on a one-to-one basis with sodium ions from a conditioning resin. Once all the sodium ions are exhausted, the resin has to be regenerated. This is currently determined by estimating the volume of water that goes through the softener and guessing when to change the resin!Even though this may work in some cases, it fails in most since the sodium content of feed water is never constant. As a result, either the resin is regenerated too early, and waste resources, or too late, risking damage due to scaling. With the pNa, you can measure the sodium content of feed water and exit water in seconds. When the resin is exhausted of sodium, there will be no exchange and the pNa will read the same value at the two ends. Only then should the resin be changed. pNa takes guess work out of resin regeneration! Hanna #: HI 98202. Range (pNa): 0.0 to 3.0 pNa (23 to 0.023 g/L Na+) Resolution (pNa): 0.1 pNa Accuracy (pNa): ±0.2 pNa Calibration: Manual, 1 point Battery Type / Life: 4 x 1.5V / approx. 800 hours of continuous use Environment: 0 to 50°C (32 to 122°F); RH max 95% Dimensions: 175 x 41 x 23 mm (6.9 x 1.6 x 0.9") Weight: 95 g (3.4 oz.) HI 98202 (pNA) is supplied with protective cap, calibration screwdriver, batteries and instructions.
