Key Features:
-
Galvanic DO/Temp probe with integrated temperature sensor and 2m cable.
-
Automatic compensation for salinity, temperature, and atmospheric pressure.
-
Stores up to 500 measurements with auto-logging and multiple measurement modes.
-
IP67 waterproof and dustproof, with shock- and scratch-resistant housing.
-
Lightweight, portable, and powered by 2 x AA batteries (over 500 hours of use).
