HM Digital is proud to release its new TRM-1, the first of its kind triple inline TDS monitor. The TRM-1 is a wide-range TDS monitor, able to measure 0-10,000 ppm, with three different TDS sensors. The TRM-1 is ideal for water filtration/purification systems that require three sensing points, such as RO/DI systems. Each sensor is ¼-inch in diameter and the TRM-1 comes standard with three ¼-inch quick-connect T-fittings (alternate sizes are available). The TRM-1 is battery powered, has auto shut-off, ATC and an accuracy of +/-2 percent (of the reading). The TRM-1 was designed in the USA and South Korea and is backed by HM Digital’s one year factory warranty.
