  • Technical specifications

Cost-effective multiprobe with portable wireless data – with interchangeable sensors, the probe replaces multiple instruments reducing overall monitoring costs. Highly stable sensors require minimal maintenance and calibration.

Reduces monitoring costs: With ultra-stable sensors that minimise 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. Interfaces with ChemScan Control Point providing local display and connection to plant control system. Telemetry integration with HydroVu platform provides realtime 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 minimise 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.

ChemScan Control Point 2.0 Monitor: Interfaces with all ChemScan family sensors. Systems can be created by the use of expansion boxes.
