LoLogLL/Vista is highly flexible yet simple and economical. Designed for portable use, it can be applied to virtually any data logging application in minutes. Once installed, LoLogLL/Vista can operate unattended until you need the data.
It is ideal for harsh applications. Both LoLogLL and LoLog Vista are available with 1 or 2 input channels but LoLog Vista has the extra benefit of an Integral LCD display, giving a clear local indication of either one or both input channels. Both are completely waterproof, submersible, and battery-powered.
