Devices intended for usage in harsh environmental conditions. Resistant to high humidity and broad temperature fluctuations, they can transmit data even totally flooded. They are equipped with own, exchangeable power sources and voltage outputs for powering external measurement sensors. Energy‑efficient design, IP68 tight enclosure and the appropriate work algorithm allow for a long‑lasting, even 5-year performance of commissioned measurement tasks and control commands.
Data is recorded in non-volatile internal memory and sent according to a set schedule and on user‑defined alarm conditions, e.g. low voltage of the power source, informing about the need to replace batteries.
