LoLog450 Data Logger

LoLog 450 is a highly flexible and cost effective data logger. Completely waterproof, submersible and battery powered it is designed for portable use and can be supplied in single or dual channel variants.

The analogue channel can be used for internal pressure and external pressure. We also offer a 4-20mA channel and our digital channel is available for flow and status data. The dual option combines one analogue and one digital channel, or two analogue channels.
