iRIS 270 Datalogger

The iRIS 270 is the perfect marriage of the proven iRIS design legacy with a future-proof architecture. It is compact, cost effective, ruggedized, IP-capable and easily configured - and due to its dual telemetry slots the iRIS 270 extends the telemetry options and the range of pluggable devices.

The dual telemetry slots support wireless 3G modem, Iridium satellite, ethernet, and RS232/RS485. They can be used to provide for communication redundancy: for example two cellular modules each with a different SIM card from independent ISP providers or a communications device connected via RS232/RS485 paired with an Iridium satellite module. Devices that will be developed in the future can be added easily.

The iRIS 270’s WiFi hotspot enables access to the device wirelessly using HyQuest Solution’s free-of-charge iLink software (Windows, Android). With a max. range of 80 m in clear line of sight (and a strong signal from the connected device), the user can edit settings while reading the staff gauge on the riverbank, doing a stream flow gauging, or sitting in his car in rainy conditions. iLink helps configuring the logger, checking settings and calibrations for QA/QC, performing real-time diagnostics to resolve technical issues, and downloading data. The optional HydroTel™ software can be used for remote configuration and data downloading.
