2420 Light Sensor Amplifier
The 2420 Light Sensor Amplifier converts the μA current from a light sensor into a voltage that can be measured by most data loggers and system controllers. The 2420 Amplifier provides 15 user-selectable gain settings to accommodate a variety of applications.
Model 2420-BNC works with light sensors that have BNC connectors.
Model 2420-BL works with light sensors that have bare leads.
Please note: LI-COR dataloggers, such as the LI-1500, do not require an amplifier because they measure the μA current directly.
