"The HYDRA is a convenient hand held syringe style meter for quick and accurate measurement of conductivity, pH and temperature of the water from your treatment system. The HYDRA is the only meter you need for your water system, as it measures pH, temperature, and conductivity in a variety of different scales (uS or mS, ppm or ppt, or MegOhms). Calibration of the HYDRA is quick and easy with just the push of a button. The easy to read digital display can read all three parameters simultaneously. The HYDRA quickly gives you the confidence that your water treatment system is working correctly."[1]
