LI19 is a high accuracy handheld read-out unit / datalogger. It is used to make mobile measurements, for short term datalogging (as a static logger), and as an accurate millivolt amplifier directly connected to a PC. LI19 can be used with a variety of sensors. LI19’s most common application is with heat flux- and solar radiation sensors. LI19 battery life and memory allow continuous measurement for up to 50 days.
LI19 is typically used to display the measured solar radiation or heat flux. It measures a DC voltage. Once programmed with the sensitivity of the connected sensor, the display will show the actual value of the heat flux or solar radiation in W/m². LI19 is programmed through its PC user interface. We recommend downloading the latest software. LI19 is battery powered, using 2 x AA-type batteries. Fresh batteries allow more than 50 days of operation. The system is supplied in a practical transport case, for easy transport and protection during field measurement campaigns. LI19 is built for easy use with a large size LCD, displaying quantities in W/m², and a USB connection. LI19 may be used with pyranometers and heat flux sensors.
