The RFCurrent2000A is a wireless DC current data logger available in three ranges: 20 mA, ±160 mA and ±3 A. The data logger can connect directly to low-level DC current sources and can also be interfaced with a wide range of current output sensors such as flow meters, pH transmitters and more.

This device features an LCD screen which provides instant access to current readings, minimum, maximum and average statistics. Equipped with user-programmable alarms, the RFCurrent2000A will alert or notify users via email or text when thresholds are breached, allowing users to take immediate action.

The RFCurrent2000A is compatible with the latest MadgeTech 4 Software making starting, stopping, and downloading simple and easy. Graphical, tabular, and summary data is provided for analysis and can be viewed as customizable engineering units.

The RFCurrent2000A is also MadgeTech Cloud Services ready, providing users the ability to monitor real-time data remotely on any internet enabled device, from anywhere in the world.

Note: RFC wireless interface required.
