Their sturdy design and military-strength connections guarantee total watertightness (IP68). Their clamping ring enables the user to access the SIM card and the battery on site. They are powered by a lithium battery with a battery life of up to 10 years.

 

Their GSM communication modes (SMS or GPRS) are based on a high-performance internal antenna specially designed for use in a buried manhole (an external antenna can be used if GSM signal reception is difficult).

 

Equipped with complex archiving functions, LT data loggers enable remote management of combined sewer overflows, diagnostics on waste and rain water networks and the supply of data related to auto-monitoring to operators.

 

Essential tools for monitoring  discharge and self-monitoring of waste water networks, SOFREL LT GPRS data loggers  are perfectly suited to installation constraints in buried combined sewer overflows (CSO)
