The menu-driven interface is easy to use. Attach your LI‑COR light sensor(s) to the three BNC connectors. Log manually or use menus to set up one-time, daily, or continual measurement routines. Sampling rates and logging intervals are user-selectable.
Use the LI‑1500 with one sensor to sample and log measurements up to 500 Hz — fast enough to measure the flicker rate of fluorescent, iridescent, incandescent, and LED light bulbs. Graph these large data sets on your computer using LI‑COR’s FV7x00 software, available for free download. Also view real-time light measurements, GPS data, and other variables on the eight-line display screen.
The LI‑1500 features an optional global positioning system (GPS) for recording the location of measurements. The GPS facilitates repeated visits to the same location for tracking light levels over time. GPS data can be logged independently or with light data.
With one gigabyte of flash memory, the LI‑1500 stores a large amount of logged data on an internal SD card.
Store configurations and sensor-specific calibration coefficient information for later use. Download your sensor’s calibration certificate from the LI‑COR web site. Enter the calibration coefficient (multiplier) and date of last calibration just once.
When attached to a computer, the LI‑1500 acts as a mass-storage device with a simple drag-and-drop file system. Logged data can be transferred to a computer with the included USB cable. Data are formatted for easy import into widely used spreadsheet and database software. Configurations and sensor calibration data can also be transferred to a computer and then shared with other LI‑1500 units.
The LI‑1500 features a rugged housing and compact design suitable for handheld outdoor use. A rubber seal between the two halves also serves as a shock cushion. The LI‑1500 is powered by four AA batteries providing over 80 hours of operation with typical usage, or 40 hours with the GPS option turned on. Power can also be supplied from an AC wall outlet with the provided USB adapter.
Use the LI‑1500 with LI‑COR sensors to log photosynthetically active radiation (PAR), global solar radiation, and light (the visible spectrum). Connect up to three sensors at the same time. For instance, use two PAR sensors to measure incident radiation above and below a plant canopy. You can also measure PAR along transects under a plant canopy.
The LI‑1500 features a built-in math function for measuring vertical attenuation using two underwater PAR sensors. The three input ports also allow for the measurement of incident PAR above water while measuring simultaneous upwelling and downwelling PAR below water.
