Brand：Erun
Name：CDOM Online Water Quality Monitor
Model：ERUN-SZ4-A-J5C
Parameter：CDOM(UV fluorescence analysis)
CDOM on-line water quality monitor ERUN-SZ4-A-J5C, based on the principle of UV fluorescence analysis, is specialised in the detection of coloured dissolvable organic compounds in water bodies, with high sensitivity and small size. The sensor has an auto-cleaning brush, which eliminates air bubbles and reduces the impact of contamination on the measurement, allowing for longer maintenance intervals, and excellent stability for long-term on-line use.

Digital sensor RS-485 output, standard MODBUS protocol; |
Adopting the principle of UV fluorescence analysis, it specialises in the detection of coloured soluble organic matter in water; |
With self-cleaning brushes to prevent bio-adhesion and longer maintenance intervals; |
| Built-in calibration parameters for easy field use and secondary calibration; |
Measures seawater and highly saline samples with low maintenance; |
Adopt LED LCD display, intelligent Chinese/English menu operation; |
Output signal: software selects 0-20mA or 4-20mA output; |
| High-resistance preamplifier: high input impedance, anti-noise, strong anti-interference ability; |
Multi-parameter display on the same screen: Simultaneously display pH (or ORP) value, temperature value, two current outputs and relay working status; |
Self-set password: Users can set or change their own passwords to avoid misuse by uninvolved personnel. |
