Product details

The DL-3 data logger has been qualified for use with Eco Sensors’ instruments and applications. It connects to and logs data from the A-22, C-30ZX, C-21, OS-4, and OS‑6 via the DC Voltage or DC Current analog outputs on these instruments. Logged data can be stored on the DL-3 and later downloaded to a computer or it can sent continuously via USB cable and displayed on the computer. A new LCD screen confirms logger operation and displays near real-time measurement data.

A special cable ($75) is required for the DL-3 to interface with most Eco Sensors instruments. Please call to place your order.
