Key Features & Specifications

The Mintaka DUO™, DUO+™ and STAR™ all have the standard features listed below.

  • Two independent, high-precision atmospheric pressure sensors
  • Pressure reading and display update every 1 second and stored every 15 seconds. Pressure at synoptic times (00z plus every 06h UTC) is recorded in it’s own file for quick reference
  • Graphic pressure history display, past 30 minutes to 120 days
  • Unique running 12-h or 24-h average pressure can be displayed to average out semi-diurnal pressure variation present in the tropics
  • Prominent pressure trend arrows provide visual warning of significant change in barometric pressure
  • Set timezone, control 12-h or 24-h display
  • Pressure units include: mb, hPa, kPa, in Hg, in H2O, cm H20
  • Choose between station or sea-level pressure display
  • Accuracy of <1 mb over full range of atmospheric pressures and temperatures at any elevation
  • Long-term drift <1 mb / yr
  • Portable or fixed location operation
  • Power: USB and 12 volts DC
  • MintakaCommander (Mac & PC): export & analyze data, provide additional functions, firmware updates, integration with other systems
  • Made in the USA

Automatically stored with each pressure reading:

  • Date & Time (high precision real-time clock)
  • Running Average (12-h or 24-h average pressure)
  • Tendency (pressure change over last 3 hours)
  • WMO/NWS Pressure Tendency Characteristic Code

Integration Support:

  • NMEA compliant sentences
  • TurboWin+ integration for weather service Voluntary Observing Ships programs

Key features of the Mintaka barograph

Standard Barograph Displays

There are multiple views of barographic pressure data. You can display the pressure over the past 30 minutes or the past 4 months, and various intervals in-between. You can read the pressure value at the cursor. You can view the WMO Tendency Characteristic Code and related graphic data. You can display a 12 hr or 24 hr moving average to smooth out diurnal pressure variation.

In history mode, you can view the pressure data over the same time ranges and a specific list of synoptic data.

Intelligent Auto-Scaling for all Pressure Ranges

Barograph data or traces is available in full-scale ranges of 30 min, 3 hr, 6 hr, 24 hr, 2 day, 4 day, 12 day, 30 day, 60 day and 120 day. Automatic self-scaling of the traces insures the best view of each data range.
