The DL6 is a dedicated soil moisture logger optimized for use with soil moisture sensors. It can be used with combinations of ThetaProbes and Profile Probes and also accepts rain gauge and soil temperature probe inputs. It is well suited to both research applications and irrigation monitoring.
DL6 Loggers include a novel accelerated logging feature to allow the tracking of wetting fronts.
As you would expect from Dynamax, the DL6 is tough and passes a 1m drop test. It is environmentally sealed (IP68) and can be used in the field without any further protection. To minimize the need for opening the case, data is collected via a weatherproof external RS-232 socket, and the status of the logger can be checked using a vibration-activated LED.
