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). **OMYL-M62 shown larger than actual size.** ## **Accuracy:** **Light:** ±(6% of reading ±2 lux) - **Relative Humidity (OMYL-M62, OMYL-M62-4M Only):** See graph below ## **SPECIFICATIONS** ## **Sensor Type** - **OMYL-M61/OMYL-M61-4M:** Single internal channel for light (luminance) **Temperature (OMYL-M62, OMYL-M62-4M Only):** See graph below - **OMYL-M62/OMYL-M62-4M** : Three internal channels for light (luminance), temperature and humidity ## **Measuring Range** ## **Light (Luminance):** 0 to 40,000 lux - **Relative Humidity (OMYL-M62, OMYL-M62-4M Only):** 0 to 100% RH ## **Temperature (OMYL-M62, OMYL-M62-4M Only):** - -30 to 70°C (-22 to 158°F) with standard battery; -40 to 90°C (-40 to 194°F) with optional high temperature battery **1** **==> picture [98 x 23] intentionally omitted <==** **----- Start of picture text -----**
