Supported Applications

The OM-CP-RHTemp101A is a humidity and temperature data logger within the NOMAD® family, designed for low-cost, state-of-the-art data logging. It features real-time clock functionality to provide time and date stamping of recorded values.

  • Monitoring environments requiring simultaneous measurement of relative humidity and temperature
  • Data retrieval via USB interface using Windows software on a PC

Operating Conditions & Performance

The logger operates across an ambient and process temperature range of -40 to 80°C (-40 to 176°F). Relative humidity is measured from 0 to 95% RH non-condensing. The device utilizes a precision RTD element for temperature sensing and an internal semi-conductor sensor for humidity.

  • Temperature accuracy: ±0.5°C (0.9°F)
  • Humidity accuracy: ±3.0% RH, with ±2% RH typical @ 25°C (77°F)
  • Resolution: 0.01°C (0.018°F) for temperature and 0.1% RH
  • Reading rate: 1-second interval capability

Configuration Options

The series supports a configurable envelope including optional certifications, software packages, and accessories to meet specific validation or connectivity needs.

Memory & Power

  • Non-volatile solid-state memory capacity: 1,000,000 readings per channel with wrap-around capability
  • Battery life indicator included; powered by a user-replaceable 3.6V lithium battery (included)

Housing & Physical Specifications

  • Enclosure material: ABS plastic
  • Dimensions: 36 L x 56 W x 16 mm D (1.4 x 2.2 x 0.6")
  • Weight: 24 g (0.9 oz)

Features & Options

  • Programmable high and low alarms with multiple start/stop functions
  • Password protection available as an option
  • NIST calibration certificate (OM-CP-RHTemp101A-CERT) offered for traceability
  • FDA 21 CFR part 11 compliant software validation package (OM-CP-SVP-SYSTEM)

Connectivity & Software

Data retrieval requires a USB interface cable and Windows software, sold separately as the OM-CP-IFC200 kit. The device supports ultra-high speed download via this connection.

Key Product Differences

The base model is designated OM-CP-RHTemp101A. Specific configurations are identified by suffixes or separate accessory part numbers:

  • OM-CP-RHTemp101A-CERT: Includes the data logger and a NIST calibration certificate.
  • OM-CP-IFC200: Windows software and 1.8 m (6') USB interface cable required to operate the device.
  • OM-CP-SVP-SYSTEM: FDA 21 CFR part 11 compliant IQ/OQ/PQ secure software validation workbook and package.
  • OM-CP-BAT105: Replacement 3.6V lithium battery.
