Supported Applications

The Omega RHXL3SD is a general-purpose handheld instrument designed for simultaneous temperature and humidity measurements, as well as dew point of ambient air, wet-bulb temperature of ambient air, and surface temperature. The microprocessor-based unit features data logging capabilities via an SD memory card.

Per manufacturer warnings, these products are not designed for use in human applications.

Operating Conditions & Performance

The RHXL3SD operates within an ambient temperature range of 0 to 50 °C (32 to 122 °F) and supports storage temperatures from -20 to 60 °C (-4 to 140 °F). Measurement ranges include:

  • Temperature: -40 to 125 °C (-40 to 257 °F)
  • Humidity: 0 to 100 %RH
  • Dew Point: -40 to 50 °C (-40 to 122 °F)
  • Wet-Bulb Temperature: -40 to 125 °C (-40 to 257 °F)
  • Surface Temperature: -40 to 125 °C (-40 to 257 °F)

The instrument provides a resolution of 0.1 °C (0.1 °F) for temperature and 0.1 %RH for humidity, with a typical response time of 10 seconds in still air.

Accuracy specifications are defined as follows:

  • Temperature: ±0.5 °C (±0.9 °F) from -20 to 85 °C (-4 to 185 °F)
  • Humidity: ±3.0 %RH from 10 to 90 %RH
  • Dew Point: ±1.0 °C (±1.8 °F) from -20 to 85 °C (-4 to 185 °F)
  • Wet-Bulb Temperature: ±1.0 °C (±1.8 °F) from -20 to 85 °C (-4 to 185 °F)
  • Surface Temperature: ±1.0 °C (±1.8 °F) from -20 to 85 °C (-4 to 185 °F)

The device is CE marked and manufactured under ISO 9001 Certified facilities in Stamford, CT and Manchester, UK.

Configuration Options

The RHXL3SD features a backlit 2-1/2 inch diagonal display. Power is supplied by six AA Alkaline batteries or an optional 9-VDC AC adapter for use with a 110VAC power supply.

  • Electrical connections include an SD card socket, RS-232 output jack, and a socket for the 9VDC AC adapter.
  • Data logging is performed to an SD card in Excel-compatible .xls format.

Available options and accessories include Type K and Type J thermocouples, a hard carrying case, and the aforementioned power supply adapter.

Key Product Differences

The series is represented by the model RHXL3SD. The instrument integrates temperature, humidity, dew point, wet-bulb, and surface temperature measurement functions into a single handheld unit with integrated data logging via SD card storage.

If i put this device into a duct with low air temeprature (-15 degrees), could it measure the humidity in the duct even if it can't measure this low temperature because it is not in the range temperature of the probe.

Asked by: moun1992
The operating and measuring range for the RHXL3SD is 0 to 50C so it is not meant to collect data outside these Temperature conditions.

how do you check the humidity

Asked by: polly
Thank you for your inquiry. To check humidity place probe in the desired location where you want to check humidity level, providing it meets the range parameters in our product specifications. Please refer to the operator's manual that shows the proper settings. Please see https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/hygrothermometers/p/RHXL3SD-Series
