Accurate Conductivity Monitoring Get precise EC and TDS readings for water quality control in homes, labs, aquariums, hydroponics, and pools. Factorycalibrated at 342 ppm NaCl, this meter delivers reliable outofbox accuracy and helps you quickly spot changes in filter performance or mineral content. Easy Inline Setup with 1/4 in TFitting Install in minutes on RO/DI systems or undersink lines using the included 1/4 inch Tfitting and rear mounting plate. The compact ABS housing measures 76 x 47 x 20 mm to fit tight spaces, and a 640 mm cable provides flexible placement options. Clear LCD and Smart Ranges A large LCD displays 0–9990 ppm with auto x10 above 999 ppm for easy reading. Resolution is 1 ppm (0–999 ppm) and 10 ppm (1000–9990 ppm), delivering a balance of sensitivity and stability for everyday water testing and tracking. BatterySaving AutoOff Powered by two 1.5 V button cells for longlasting operation, with autooff after 10 minutes of inactivity to extend battery life when the meter is installed for continuous availability but not actively checked. Applications Home drinking water and filter performance monitoring to ensure quality and consistency Aquarium and hydroponics systems to protect plants and aquatic life from fluctuating mineral levels Inline monitoring for RO/DI or undersink installations to verify water quality before use
