Testomat LIMIT
Online Limit Value Analyzer for Total Hardness
Key features:
- Continuous hardness monitoring every 1 – 60 minutes
- Set alarm point between 0.89 – 445 ppm CaCO3 total hardness
- Touchscreen for easy set up
- Self-calibrating
- Low water and reagent consumption
- Low maintenance requirements
Optimize water quality testing with the Testomat LIMIT®, an automated solution for total hardness determination that uses a precise titration method. Immediate notifications via alarms are triggered when water hardness exceeds defined limits. Set alarm point between 0.89 – 445 ppm CaCO3 total hardness
Testomat LIMIT® seamlessly integrates with other systems, transmitting results directly to a PLC, softener, or filters for automatic corrective actions. By proactively calculating reagent availability, the Testomat LIMIT® significantly enhances operational efficiency.
