The uv-bug and the lux-bug are single channel stand-alone data loggers for the measurement and recording of visible light and UV levels. The standard ranges are 0 to 2000 Lux and 0...5000mW/m2, other ranges are available on request. The sensors are fully cosine corrected and can be mounted either in the front of the unit, as illustrated, or on a remote cable.

SENSORS
Lux is detected by a photometric diode and UV by a UV-enhanced silicon photodiode fitted with a hard UV filter material which provides a response over the range 250..400nm, with cosine-correction of both Lux and UV.

MEMORY
The lux-bug and uv-bug loggers have up to twice the memory of other loggers on the market. 16k of incorruptible EEPROM memory allows up to one year of data logging at the maximum recording interval. Data is stored to 10 bit resolution.

HIGH SPEED COMMUNICATIONS
Hanlog loggers have full specification RS232 comms. at 19200 Baud. Most other loggers provide only marginal levels at a much lower Baud rate. The result of this is that loggers, such as the lux and uv-bugs, download their entire memory in less than 15 seconds.

SOFTWARE
Included with the uv-bug and the lux-bug is a fully featured Windows software package. Logged data is swiftly downloaded and can then be filed in a database for later retrieval and analysis. Cumulative Lux and UV calculations are performed automatically.
