Brand：Erun
Name: Online Oil in Water Monitor
Model：ERUN-SZ4-A-J4
Parameter：Oil (UV fluorescence method)
ERUN-SZ4-A-J4 on-line oil-in-water monitor sensor, which is based on the principle of UV fluorescence method, is known for its high efficiency and speed, while showing excellent repeatability. It not only realizes online real-time monitoring of dissolved and emulsified oils, but also ensures the continuity and accuracy of the detection process.

The UV fluorescence method is used with high sensitivity; |
No reagents needed, strong anti-interference, no need for frequent calibration; |
Optional titanium alloy allows measurement of seawater and high salt content samples with low maintenance; |
| Built-in calibration parameters for easy field use and secondary calibration; |
Adopt RS485 digital output, support Modbus protocol. |
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. |
