Viomax CAS51D – Digital Nitrate and SAC Sensor
The Endress+Hauser Viomax CAS51D uses UV absorption spectroscopy to simultaneously measure nitrate and SAC (Spectral Absorption Coefficient) without any reagents. This makes it ideal for continuous water quality monitoring.
Key Features
- Measuring principle: UV absorption (254 nm)
- Parameters: Nitrate (NO₃-N), SAC (organic load)
- Nitrate range: 0 to 50 mg/l NO₃-N
- SAC range: 0 to 1000 m⁻¹
- No reagents required
- Memosens digital technology
- Process temperature: 0 to +40 °C
- Self-cleaning wiper (optional)
- Compatible with Liquiline CM4xx transmitters
Applications
Wastewater treatment (effluent monitoring), drinking water quality, river monitoring, industrial process water, regulatory compliance.
