OVERVIEW
An optional analog module with four analog inputs that support excitation power, scaling, and statistics measurements. These four, single-ended sensor inputs are configured through LI-COR Cloud IoT Platform (formerly HOBOlink). A HOBO RX3000 is required for this product.
Features
- 15-bit resolution and high accuracy
- Each module can have its own logging rate
- Input ranges up to 33V
