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.

This innovative logger uses the latest integral cellular telemetry technology to provide rapid transmission at low cost.

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.
