Frequently Asked Questions (FAQ)
Q What parameters can the Portable Multi-parameter Water Quality Analyzer measure?
The analyzer supports multiple customizable parameters including Dissolved Oxygen (DO), pH, Conductivity/EC, Salinity (SAL), Turbidity (TUR), Temperature, ORP, COD, TSS, Ammonia Nitrogen, Chlorophyll, and more — depending on the sensor probes installed.
Q How many sensors can be connected to the analyzer simultaneously?
The analyzer features a universal platform that allows multiple Luminsens sensors to be freely inserted at the same time. Each sensor is automatically recognized by the device, enabling multi-parameter monitoring in a single deployment.
Q What communication protocol does the analyzer support?
The analyzer and its digital RS485 sensors support RS-485 interface with MODBUS protocol, making it easy to integrate with SCADA systems, data loggers, and other industrial control systems.
Q Can the cable length be customized for deep-water or remote deployments?
Yes. The standard cable length is 5 meters, but it can be extended according to user requirements, making it suitable for deeper water bodies, remote monitoring stations, or challenging field environments.
Q How is calibration managed for each sensor?
All calibration parameters are stored directly within each individual sensor. This means when a sensor is replaced or swapped, calibration data is retained automatically, simplifying maintenance and reducing downtime.
