COMlog 2 IS

COMlog 2 IS

COMlog 2 IS is the intrinsically safe, highly versatile data logger designed to be a cost-effective, multi-application solution.

Developed for flexibility, COMlog 2 IS is compatible with any sensor or meter that has a volt-free pulsed output.

Particularly effective for smart metering, COMlog 2 IS provides businesses with an efficient way of managing gas and energy consumption and reducing costs.



COMlog 2 IS is compatible with any meter that has a volt-free pulsed output and uses accumulative pulse counting technology to calculate index readings against a known volume.

COMlog 2 IS transmits data through an integral modem with GPRS/2G, 4G. LTE-M (Cat-1) and other NBIoT options available.

The replaceable internal batteries will typically power the device for five years when data is transmitted every eight hours.

COMlog 2 IS is also supplied with an external antenna connection that enables the use of a range of specialist antennas to address the most extreme low signal level locations.
