Omega RHXL3SD Handheld Temperature and Humidity Meter with Data Logger
  • Real Time Data Logger (Temperature/Humidity Only). Stores Data in CSV Format to 2 GB SD Card (included)
  • Temperature and Humidity Probe
  • MAX/MIN/HOLD Function
  • Dew Point Measurement (Display Only)
  • Wet Bulb Temperature (Display Only)
  • J/K Thermocouple Input
  • Auto Power Off Feature
  • USB Cable or RS232 Cable (Optional)
  • Windows Software (Optional)


The RHXL3SD is supplied with a probe that is used to measure ambient temperature, humidity and dewpoint. Surface temperature measurements can be made using an optional Type K or J thermocouple.
Several features and capabilities enhance the RHXL3SD's versatility. Among them are automatic temperature compensation for dew point, wet-bulb and thermocouple measurements; the ability to hold readings and display maximum and minimum values; and an automatic power off function that extends battery life.

A built in SD memory card slot allows recording of measured data directly onto the supplied 2GB SD card. Measurements can be logged automatically at any sampling rate between one second and one hour. The user can remove the memory card and plug it into a laptop or desktop computer either directly or via a USB card reader. The recorded data is stored on the card in a file format that can be opened by Microsoft Excel. SD memory cards with a capacity of up to 16 GB are compatible. The RHXL3SD has a backlit display and is powered by 6 "AA" alkaline batteries or an optional AC adaptor.
