Self-Developed Core Technology
As an independently developed product by ERUN Group, the M7B offers superior stability and consistency compared to generic sensors, ensuring long-term reliability in critical processes.
Dual-Parameter Measurement
Simultaneously measures Calcium Ion concentration and Temperature. This 2-in-1 capability provides comprehensive data for precise water chemistry analysis.
Automatic Temperature Compensation (ATC)
Fluctuating water temperatures can affect ion activity. The ERUN-M7B automatically detects temperature changes and performs real-time compensation, ensuring consistent accuracy across varying thermal conditions.
High Stability & Precision
Designed to minimize drift and calibration frequency, the M7B provides high-resolution data even in complex solutions, reducing operational downtime and maintenance costs.
Rugged & Versatile Design
With a robust build quality, this sensor is engineered to withstand the harsh conditions found in professional applications.
