Frequently Asked Questions (FAQ)
Q What parameters can the Portable Multi-parameter Water Quality Analyzer measure?
The analyzer supports a wide range of parameters including Dissolved Oxygen (DO), pH, Electrical Conductivity (EC/CT), Salinity (SAL), Turbidity (TUR), Temperature, ORP, COD, TSS, Ammonia Nitrogen, Chlorophyll, Blue-Green Algae, Residual Chlorine, 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 and automatically recognized. The number of sensors supported depends on the available sensor compartments on the unit. Each compartment is independently designed so a malfunction in one will not affect the others.
Q What communication protocol does the analyzer support?
The analyzer and all digital RS485 sensors support RS-485 communication with the MODBUS protocol, enabling easy integration with SCADA systems, data loggers, and other industrial control equipment.
Q How is the analyzer powered, and how long does the battery last?
The analyzer is powered by a rechargeable lithium battery and comes with a 220V to DC charging adapter. The sensors operate on DC 12–24V. Battery life varies depending on the number of sensors connected and the measurement frequency during field deployment.
Q Can the cable length be customized for deep-water deployment?
Yes. The standard cable length is 5 meters, but it can be extended according to user requirements, making it suitable for deeper water bodies such as reservoirs, lakes, or marine environments.
Q Is the analyzer suitable for use in harsh environmental conditions?
Yes. The analyzer is designed to operate in working conditions from 0℃ to 50℃ and can be stored in temperatures ranging from -40℃ to 85℃. It is also equipped with an internal humidity detection and alarm function to protect the device in challenging field environments.
