6-Port Global Data Transmitter Web Entry

Advantages

The GDT-M is a 6-port telemetric modem.

Up to 6 Diver water level loggers can be attached.

The GDT collects the data from the loggers and transmits the data to you, either by email or so that it is viewable on a website, without the need for any specialist software.

Programming of the GDT, such as transmit times, wake up intervals and alarm settings can be done remotely from your desktop anywhere in the World.

With a very long battery life the GDT-M is ideal for continuous onsite water level monitoring.

Benefits:

•Smart and efficient

•Lower data costs

•Long battery life

•Internal barometric compensation

•Remote management of modem and loggers saves hour of field work

•Global data coverage over a GPRS network, or UMTS if you operate from a country where GPRS is not available

•Can be fitted retrospectively and expanded at any time

•Fully backed by the Van Walt Technical team.
