Description
This product line has been discontinued. For an alternate product, please see our wide selection of temperature and humidity loggers here.
OMYL-M61 and OMYL-M62 light data loggers record
luminance with a spectral sensitivity adjusted to the
spectrum of the human eye. These data loggers are
available with standard memory of 100,000 readings
(OMYL-M61, OMYL-M62) or expanded memory of 4
million readings (OMYL-M61-4M, OMYL-M62-4M).
Models OMYL-M61 and OMYL-M61-4M have one
internal channel for light measurement. Models
OMYL-M62 and OMYL-M62-4M models have three
internal channels for measuring light, temperature
and humidity. These data loggers are typically used
in weather stations, museums, street lighting or
commercial/industrial lighting studies.
The storage medium is non-volatile flash memory so
no data is lost if the battery becomes discharged. Data
logger setup as well as data retrieval is accomplished
using the included standard OMYL-SOFT software.
Downloaded data is stored in the OMYL-SOFT software
as a text file for viewing in third party software packages
or Microsoft Excel. The OMYL-SOFT standard software
does not include any graphing functionality. Graphing
and analyzing downloaded data files requires the OMYLSOFT-
PLUS version of the software (sold separately).
