Supported Applications

The OM-62 is a compact, lightweight, easy-to-use USB data logger, part of the NOMAD® Family, that measures temperature, relative humidity, and dew point simultaneously. Its small size and push-button or PC-controlled recording make it well suited to portable environmental studies, warehouse and cold-storage monitoring, and shipment surveys.

Because it includes Windows software for data display, analysis, and export and connects directly over USB, it fits laboratory, quality-control, and facilities applications where recorded data must be reviewed and archived on a PC without additional interface hardware.

Operating Conditions & Performance

The logger measures temperature over -40 to 70°C (-40 to 158°F) with an internal digital sensor, and relative humidity over 0 to 99% RH, non-condensing using a polymer capacitive sensor.

Temperature accuracy: ±0.5°C (±1°F).
Temperature resolution: ±0.1°C (±0.1°F).
Relative humidity accuracy: ±2% RH from 10 to 90% RH.
Relative humidity resolution: 0.01% RH.
Sampling rate: user selectable, 1 second to 18 hours, in 1 second increments.
Storage temperature: -40 to 70°C (-40 to 158°F).
Power: 3V lithium battery (included).
Weight: 28 g (1 oz).
Dimensions: 76 H x 40 W x 15 mm D (3.0 x 1.6 x 0.6").

Data storage is 43,344 readings for temperature only and 21,672 for temperature and humidity. Recording modes are user selectable — stop on memory full or continuous recording with memory rollover — and both temperature and humidity support programmable high and low alarm thresholds. The device carries CE and a 1 year warranty.

Configuration Options

The series comprises two loggers that share the same compact USB body, 3V lithium battery, and Windows software, differing in whether they include the relative-humidity channel:

OM-62 — Temperature and Relative Humidity

The OM-62 combines the internal digital temperature sensor with a polymer capacitive humidity sensor, measuring temperature, relative humidity, and dew point simultaneously. Its data storage splits accordingly — 43,344 readings when logging temperature only and 21,672 readings when logging both temperature and humidity.

OM-63 — Temperature

The OM-63 is the temperature-focused member of the series, omitting the humidity channel while retaining the same USB interface, recording control, and software workflow.
