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. Simultaneous, multi-parameter measurement from a single probe with a range of optional sensors. Measures temperature, depth, pH, ORP, conductivity, salinity, TDS, turbidity, and dissolved oxygen. Additional sensors also available for chlorophyll, blue-green algae, ammonia nitrate, chloride and fluoride. Optional Bluetooth communication for wireless data transmission RS485 Modbus output for integration with data loggers and monitoring systems Field-replaceable electrodes for easy maintenance Optional self-cleaning system for long term accuracy in continuous monitoring environments Typical Applications Environmental water monitoring of rivers lakes and reservoirs Drinking water source monitoring Groundwater quality assessment Marine and coastal water monitoring Environmental research and field surveys Aquaculture water quality management Municipal water resource monitoring  Specifications Sensor Parameter Measurement Principle Range Resolution Accuracy Depth Pressure sensitive method 0 to 30 m 2 cm ±0.3% Temperature Thermistor method 0 to 50 °C 0.01 °C ±0.1 °C pH Glass pH electrode 0 to 14 pH 0.01 pH ±0.1 pH Conductivity Platinum electrode pair 1 µS/cm to 2000 µS/cm (K=1) 100 µS/cm to 100 mS/cm (K=10) 0.1 µS/cm to 0.01 mS/cm ±3% Turbidity Light scattering method 0 to 1000 NTU 0.1 NTU ±5% Dissolved Oxygen Fluorescence 0 to 20 mg/L 0 to 20 ppm 0 to 200% 0.01 mg/L or 0.1% ±0.1 mg/L (<8 mg/L) ±0.2 mg/L (>8 mg/L) Chlorophyll Fluorescence 0 to 500 µg/L 0.1 µg/L ±5% Blue-green Algae Fluorescence 100 to 300000 cells/mL 20 cells/mL ±5% Ammonia Nitrogen (NH₃-N) Ion selective electrode 0.1 to 100 mg/L-N 0.01 mg/L-N ±10% or ±2 mg/L Nitrate Nitrogen (NO₃-N) Ion selective electrode 0.5 to 100 mg/L-N 0.01 mg/L-N ±10% or ±2 mg/L Chloride Ion (Cl-) Ion selective electrode 3 to 1000 mg/L 0.01 to 1 mg/L ±10% or ±2 mg/L Fluoride Ion (F-) Ion selective electrode 0.5 to 1000 mg/L 0.01 to 1 mg/L ±10% or ±2 mg/L   Downloads Portable Multi-Parameter Water Quality Analyzer Datasheet Portable Multi-Parameter Water Quality Analyzer Users Manual Optional Probes Turbidity Sensor Optical turbidity sensor using light scattering for suspended solids measurement.
