SCYLAR INT 8
SCYLAR INT 8 is a high-precision calculator designed to meet European standards. It measures heating, cooling energy and can be used in combined mode too. SCYLAR INT 8 enables the utility to monitor and optimize its metering remotely; it can be directly connected to a Centralized Technical Management unit, to provide large quantities of instant or saved parameters.
