ChemScan MPX4 Multiparameter Sonde The ChemScan MPX4 is a cost-effective multiprobe that integrates with plant control systems for long-term installation using a local controller, direct connection or wireless telemetry. The probe can also be used for spot checking using Bluetooth data collection. With interchangeable sensors, the probe replaces multiple instruments, reducing overall monitoring costs. And highly stable sensors require minimal maintenace and calibration. BENEFITS • Reduces monitoring costs: With ultra-stable sensors that minimize calibration and maintenance needs, the multiprobe reduces total cost of ownership. • Saves hours on fieldwork: The VuSitu mobile app records data directly from the probe for spot checks. The ChemScan/Partech 7300w2 monitor can interface with the probe, providing local display and connection to plant control system. Telemetry integration with HydroVu platform provides real-time access to remote monitoring data. Delivers higher-quality data: Drift-resistant sensors with simplified calibration provide accurate, reliable data - no messy field notebooks required. When using the instrument as a handheld, our mobile app walks you through SOPs to minimize errors. Rugged design with optional antifouling wiper ensures performance in harsh environments for longer deployments. Ease of use: Streamlined data collection and automatic environmental compensation mean zero-processing, while our mobile app lets you tag sites and track GPS coordinates. FEATURES • Interchangeable sensors with wet-mate connectors • Optional 2” antifouling wiper for higher-quality data in long-term deployment • Wireless mobile Bluetooth® connection for iOS/Android (VuSitu app) • Site tagging and GPS coordinate functions available via app • LCD display gives snapshot of instruments health and connectivity • Wide sensor range for performance in a variety of applications • Barometric environmental compensation - no data postprocessing • Easy integration with PLC/SCADA control systems, data loggers, and telemetry - no adaptors or confusing communication protocols • Innovative pH and ISE reference for 3X sensor stability • Corrosion-resistant housing and abrasion-resistant RDO sensor PARAMETERS • Temperature/Conductivity • Pressure • Level • Salinity • pH/ORP • Nitrate (NO3-) • Rhodamine WT Fluorescence Intensity Ammonium (NH4+) Chloride (Cl-) Turbidity Total Suspended Solids Dissolved Oxygen (RDO) Blue Green AlgaePhycocerythrin Applications: • LONG-TERM DRINKING WATER AND WASTEWATER PROCESS MONITORING • REMOTE MONITOR
