Isodaq: Proven Technology:

Isodaq  data  loggers  are  rugged  solutions  enabling organizations  and  businesses  to  perform  water  and environmental monitoring and gain online access to precision measurements at remote sites.

Designed for unattended operation in harsh environments, the Frog RX is the ideal choice for water or drainage monitoring at remote sites. For effective water level measurement, the Frog features precision sensors for flood warning applications in boreholes, reservoirs and rivers.

The Frog RX operates either as a standalone battery-powered data logger or as a telemetry logger, and is available in two alternative firmware versions of 8 or 16 channels. The Frog also enables connection to ‘smart sensors’ via its SDI-12-compatible multi-channel expansion port, allowing use of flow meters, pressure sensors, water quality probes etc.

Isodaq products are ideal for use by:

  • Environmental consultants and regulators

  • Government departments and research organizations

  • Local drainage and river authorities

  • Water and Mineral extraction companies

  • National environmental regulators

  • Building contractors and developers

Nothing’s Simpler: Just Leave the Frog to Log!

Isodaq is much simpler than competing monitoring products, has a much lower price point, and has a shorter installation time and cost. It’s easy to install the Frog inside 100mm (4ins) tubes, to strap it onto poles/piezometers or fit it inside ground-level meter boxes without needing a secondary enclosure. Completely self-contained, the Frog RX is sealed to IP 68 against harsh weather conditions and can also withstand full submersion for short periods.

With no IT issues to worry about, Isodaq has no host software to install or learn—just configure and deploy! The Frog automatically sends the data to a PC via the Isodaq webserver so users can view real-time data remotely. For regulatory needs, all measurements are stored in a database accessible over Isodaq’s secure RTU server. From there, users can just print it out.
