Multi-Parameter Water Quality Sonde Sensor Housing
The Multi-Parameter Sonde Water Quality Sensor Housing is designed for rapid on-site (in situ) water quality monitoring across a wide range of environmental and industrial applications.
This advanced sonde sensor housing integrates multiple sensors into a single probe, allowing simultaneous measurement of critical water quality parameters with high precision and reliability.
Notes:
1) This is for the SENSOR HOUSING ONLY- you must purchase each sensor separately in addition to the housing. Sensor housing includes temperature, depth (pressure) sensors.
2) The sensor housing can be connected to either the Portable Multi-Parameter Water Quality Analyzer, or integrated with 3rd party data loggers or remote monitoring systems via built-in RS485 Modbus output and Bluetooth wireless capability.
3) This unit ships direct from the factory. Please allow an additional 5-10 working days for shipment and delivery.
The integrated multi-parameter sensor measures a wide range of water quality indicators, including depth, temperature, pH, ORP, conductivity, turbidity, dissolved oxygen, chlorophyll, blue-green algae, ammonia nitrogen, nitrate, potassium, fluoride and chloride. This allows comprehensive monitoring of physical, chemical and biological conditions in natural water.
Eight parameters use analog electrodes: pH, conductivity, ORP, ammonia nitrogen, nitrate, potassium, fluoride and chloride. Up to four of these can be selected at one time, with no duplication.
Each electrode connects to a fixed, labeled port on the device and ports are not interchangeable. Labels include pH for pH, C for conductivity, OR for ORP, NH for ammonia, NO for nitrate, F for fluoride, CL for chloride and K for potassium. Numbered ports 1 through 4 correspond to specific electrode assignments, while numbered ports alone indicate digital electrode connections.
Note: Electrode configurations are set at the factory. The device will not detect or alert if a configured electrode is disconnected and may still display a reading even when the sensor is not physically connected.
