uDL1 Data Logger
with GPS Receiver

Optional internal GPS receiver provides an accurate time reference and site geo-location coordinates

Description

The uDL1 is a high accuracy, low cost data logger designed specifically for cathodic applications. The device is very simple to use and has a large LCD that can locally verify the readings. Measurement storage capacity of 500,000 or 1,000,000 readings and long life rechargeable battery allow the device to capture readings for over 6 months. An optional internal GPS receiver provides an accurate time reference and site geo-location coordinates. A small physical size and wide operating temperature range make this device ideally suited for general field use.
