COMPATIBILITY & APPLICATIONS
Universal System Monitoring
The Sennotech B&A TDS-3/8 monitor is designed for universal compatibility with reverse osmosis systems, deionization units, and any water treatment system using 3/8" tubing. The dual-probe design measures inlet water quality and post-treatment output simultaneously, calculating removal efficiency in real time. Ideal for RO systems, whole-house filters, aquarium filtration, hydroponic applications, and any scenario where continuous TDS monitoring validates filter performance. Generic mounting design allows installation on countertops, under-sink cabinets, or filter housings without modification. Button-controlled operation extends battery life by activating the display only when needed.
💧 Pro Tip: A sudden drop in removal rate (red flash) often indicates membrane fouling or pre-filter exhaustion before you notice taste or flow changes. Use this meter as an early warning system to schedule filter replacements based on performance, not arbitrary timelines.
