Software Specifications (CalexConfig):

Operating SystemWindows
FeaturesTemperature display, scrolling temperature chart, sensor configuration, data acquisition with scheduled start, on-screen alarm
Data Log File Format.csd (comma-separated text format, may be imported to spreadsheet software such as Excel)
Data Transmission ProtocolModbus over USB (it is possible to communicate with the sensor for temperature measurement and configuration using third-party software. Protocol information is provided in the instruction manual.)

Environmental Specifications:

Environmental RatingIP65
Ambient Temperature Range0ºC to 70ºC (cooling option available for use in higher ambient temperatures)
Relative Humidity95% max. non-condensing
Please note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because PyroUSB sensors detect only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
