Contest Overview

HL_Sonde SurvivorAround the world, Hydrolab instrumentation is put to the test in a wide variety of diverse and challenging applications to get users the water quality data they need to make critical water resource management decisions.

To allow our users to highlight their interesting applications with one another and to see who has the “toughest” application, we’ve created the Sonde Survivor contest!

Criteria for winning is based on which Hydrolab application is the most unique and includes the “toughest use” of the Hydrolab.
