T&D Data Logger


TR-71W and 72W

The TR-7W loggers, with built in network functioning allow you to easily connect to the Internet or LAN type
network. This networking function makes it easy, not only to gather recorded data and monitor current readings from any distance, but also to have warning mail sent to your cell phone or other mail address.
Of course, these loggers can be connected via a wired LAN network or can be easily set up to be used with a Wireless LAN network, thus making troublesome cables and wires a thing of the past and extending the placemant possibilities of loggers.

TR-71W TR-72W

 Functions

Gather Data via the Internet
By taking advantage of the infrastructure of the widely available Internet or other LAN network system, the monitoring of current readings or the gathering of data can be done with great ease from just about anywhere. Further, loggers placed in the field are built to take advantage of e-mail and can instantly send warning report e-mails whenever a set temperature or humidity has been exceeded.

LAN:100BASE-TX, 10BASE-TX compatible
View Real Time Readings and Graphs on your Internet Browser
By using your Internet browser to access the TR-7W it is possible to view current real-time temperature and humidity readings as well as view up to the past 7 days worth of recorded data in graph form. It is also possible to use your Internet browser to download all of the recorded data in the logger as a file and then use our exclusive software that comes with the unit to process and manage as temperature and humidity data.

*We suggest using " Microsoft Internet Explorer " as your Internet browser
*The Graph display on the Internet browser is a simplified version.
Wireless LAN Compatibility brings you Frexibility and Freedom
By inserting a CF type Wireless LAN card into the card slot on the data logger, the data logger can be easily integrated into your wireless LAN system.This function not only reduces the need for troublesome LAN cables, but also offers you increased flexibility and freedom in placing the units in the field.

*Please use only CF Wireless Cards that we have found to be compatible.
See our Homepage for details.

*1 1 Compatible with all T&D tested and approved models.
*2 Errors in accuracy increase with increase in electrical noise.
*3 Battery Life varies according to type of battery, measuring environment , communication frequency, and ambient temperature. This estimate of battery life was based on normal use under normal conditions using a new battery.This is in no way a gurantee of battery life.
*4 Without protrusion
*5 The backup battery is for data backup and emergency use only. The battery is not used under normal conditions. If using only the battery, network communication cannot occur.
*6 Please do not use any CF type Wireless LAN cards that have not been proven to be compatible and are not in the list below. Please ask your local representative about which Wireless LAN cards can be used. For an updated list of Wireless LAN cards that have been tested and proven compatible please see our Homepage.
