Dataloggers and Light Meters
LI-1400 Datalogger
As an autoranging meter, the LI-1400 provides direct read-out for up to three LI-COR radiation sensors without requiring a terminal input block. Output can be viewed on the LCD display or stored in memory by simply pressing the ENTER key on the keypad (data for all operative channels are stored, along with the time at which the data were logged). Additional sensors can be connected via an optional terminal block. Radiation measurements in water or under changing cloud cover often require an averaged reading of sensor output to obtain the best results. The LI-1400 can display a continuous running average for each sensor. The length of the average is user selectable for each channel. Instantaneous or averaged values for any sensor can also be displayed while the LI-1400 is logging data.
- Simplified data logging
- Fast setup
- Additional current and voltage channels
- Easy calculations using math functions
LI-250A Light Meter
The LI-250A Light Meter is a simple read-out device for use with LI-COR's sensors. One sensor at a time can be connected to the meter via the BNC connector on the top of the device. A large display screen displays the data with the correct units. Users can press "HOLD" to pause the readings, or "AVERAGE" for a ten-second average.
- Quick setup
- Simple, easy operation
- Stores up to two multipliers
