This compact, blue and white device is designed for inline installation in filtration setups such as reverse osmosis (RO) and deionization (DI). It provides real-time readouts for both incoming feed water and the purified product water, helping you observe how dissolved solids move through your system. Whether mounted under the sink, in a cooler, or on a countertop filtration line, the DM-1 offers a clear, at-a-glance view of TDS levels right where you monitor your filtration journey.\u003c\/p\u003e\u003ch2\u003eWhat it does\u003c\/h2\u003e\u003cp\u003eThe DM-1 displays TDS readings from 0 to 9990 ppm for each leg of the flow path, using dual electrode probes placed before and after your filtration stage. Its microprocessor-driven readout emphasizes precision, delivering results with a stated accuracy of ±2% in typical use. This inline approach lets you compare feed water against product water without additional sampling steps, which can help you assess overall system performance over time.\u003c\/p\u003e\u003ch2\u003eWhat’s included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eInline monitor unit with dual probes\u003c\/li\u003e\n\u003cli\u003eTwo TDS sensors\u003c\/li\u003e\n\u003cli\u003eTwo 1\/4\" quick-connect fittings\u003c\/li\u003e\n\u003cli\u003eBatteries for immediate operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow to use\u003c\/h2\u003e\u003cp\u003eInstall the DM-1 inline: place the \u003cstrong\u003eIN\u003c\/strong\u003e sensor on the incoming tap water line and the \u003cstrong\u003eOUT\u003c\/strong\u003e sensor on the product water line after filtration.
