monitor is designed for continuous measurement and
conversion of selected environmental parameters into a digital form (prot. Modbus
TCP/IP, Modbus RTU , HTTP). The monitor programming is possible with the
built-in web server.
The monitor has an LCD display field with 2x16 characters. The
device allows you to send e-mail messages informing about the current environmental
parameters as well as events
that cause exceeding the alarm values. The monitor is
powered via Ethernet - PoE (Power
Over Ethernet) or standard DC jack.
Features of
