EnviroLog

EnviroLog is a standalone environmental hub that incorporates all that you require for a survey operation - command and control of your sensors, data display, data logging and battery power in a small robust package.

Multiple devices can be interfaced to EnviroLog where a user-definable observation scenario can be programmed to control those devices as a group. EnviroLog is optimised for Valeport’s Hyperion range of optical sensors.

  • Fluorometers:
    • Chlorophyll a
    • Fluorescein
    • Sulforhodamine B
    • Rhodamine WT
    • Phycocyanin
  • Turbidity

EnviroLog will automatically recognise the type of sensor interfaced and suitable header and units fields can be populated.

A 7.2 or 14Ah battery can be fitted to supply power for all three sensors. The data is stored internally and can be recovered either over Bluetooth or through the serial comms\charging port.

Software

The EnviroLog is configured with dedicated software - EnviroLOG. The software allows you to configure the EnviroLog, not the instrument.
EnviroLOG software can identify the Hyperions interfaced to the EnviroLog System and program the observation schedule and start time and date.
Valeport Configure should be used to set up the Hyperion instrument prior to interfacing to the EnviroLog.
Both EnviroLOG and Valeport Configure software can be downloaded from the Valeport Water website and are licence free.
