The Series WTDL Temperature/Humidity Data Logger
is perfect for applications
which require real time monitoring or in areas that are not as accessible to
periodically retrieve the loggers The data loggers can transmit up to 500 feet
indoors and up to 2000 feet outdoors The distance can be increased by using
additional receivers Wireless data is transmitted on a 2 4 GHz frequency allowing
it to be used anywhere in the world A network of data loggers can be separated
into a smaller subnet These subnets can all be controlled by a single PC The
Series WTDL data loggers also feature a user programmable alarm This alarm
can be configured to show an on screen alarm send a text message (standard
SMS rates apply) or an email if an alarm condition is met
