The Testomat EVO TH from Heyl USA is an inline field-measuring instrument that automatically analyzes water hardness concentrations in a quantity- or time-controlled basis. If water quality is checked manually, water hardness may go undetected. This leads to lime scale buildup, which increases energy and maintenance costs. Once implemented, the unit helps reduce operating costs and increase energy efficiency. With an integrated Wi-Fi SD card, monitored data is delivered in real time to mobile devices for flexible data collection and management. Error reports and alarms are sent wirelessly to notify when immediate action is needed. 312/377-6123; www.heyl.de.
