Simultaneously monitors and controls the TDS levels of two water lines (e.g., the feed water and product water) for high output commercial systems. Large, bright LED displays. An alarm sounds if TDS level rises above user-set level for either line. Installs easily in minutes. Includes two 1/2" sensor probes.

• Range: 0 – 9999 ppm
• Accuracy: ±2%
• Conversion Factor: NaCl (avg. 0.5)
• Resolution: 0.1ppm (0-99.9), 1ppm (100-9999)
• ATC: Yes (1-60°C)
• Calibration: Up and Down push button digital calibration
