Dataloggers Put to the Test
by Malcolm Barr
Our dataloggers are designed to work in some pretty extreme conditions and to keep working for a long time unattended. We put a lot of effort into ensuring this is the case and are proud of our results.
Occasionally the limits of our gear have really been put to the test. In April, a major fire on the historic wharf at Raglan destroyed an iRIS 320 and all of the monitoring equipment with it. Then earlier this month, another iRIS 320 came close to suffering the same fate on the Waikanae river. The iRIS is actually in the enclosure at the top of the green pole and was unharmed by the fire.
The harsh treatment of dataloggers is not new. This logger took a direct lightning strike via the radio aerial. You can see where the pressure inside the logger has bent the lid against the central screw holding it on (unfortunately this logger didn't survive and is now a museum piece):
The good news is that these are definitely the extremes!
