The WHA-3000 Online Hardness Analyzer is an online analyzer designed to measure water hardness levels (in ppm) in purification and water treatment applications (Softeners, R.O., etc.). It can be used to automatically control the regeneration of devices, especially those with timer and volumetric control. With the sensor attached to the soft water outlet, regeneration can be started independent of time and flow when the outlet water reaches a certain hardness. Ideal for both savings and guaranteed operation.
