VWR® Traceable® Digital Barometer, 24-Hour Recall

Monitor environmental air conditions with a digital barometer that displays pressure, temperature, humidity and trend data at a glance for labs, plant areas and indoor environments.

• Four-line LCD displays pressure, temperature, humidity, trend, and time together
• Hourly min/max memory helps review environmental changes over the last day
• Selectable pressure units support easier interpretation across reporting preferences
• Altitude compensation improves relevance above or below sea-level conditions
• Traceable calibration certificate supports documented measurement confidence in monitored spaces

This digital barometer fits routine environmental checks where atmospheric conditions can influence experiments, storage spaces, or general facility awareness. The multi-parameter display helps users review key room conditions from one instrument instead of checking separate devices.

For review and recordkeeping, the unit stores hourly minimum/maximum readings for pressure, temperature, and RH for the last 24 hours. It displays this pressure trend history in a bar chart view with current plus prior 1, 3, 6, 12 and 24-hour readings. Altitude compensation is adjustable from 100 to 2500 meters to help align readings to your location.

The instrument is suited for bench or wall placement, making it easy to position where readings need to remain visible during the workday. For longer-term documentation, it can be used with a compatible data acquisition system (sold separately), while the included traceable calibration certificate supports confidence in routine monitoring.
