Overview
The versatile Ott netDL 500 and 1000 data loggers were developed specifically for use in hydrology and meteorology stations. In addition to recording data, the data loggers are extremely low power and offer flexible data transfer options via the internet and mobile networks, providing a logging and telemetry solution for every project.
Benefits
Ethernet, USB-Host, USB-Device, RS-232, Satellite, Cellular, Industrial Communication
SDI-12, RS-485 (SDI-12), Modbus RTU, analogue-in (voltage and current), Impulse Input, Status Input
Due to large memory and redundant communication, Multitasking capability for short polling cycles
Extremely low power consumption allows prolonged use at remote locations
Integrated display allows for easy local interaction
Using OTT HydroMet software the logger can be reached from all over the world via IP without the need of a static IP address.
