Traceable Handheld Digital Barometer.

The Handheld Digital Barometer measures altitude, temperature, and barometric pressure.  It also has a stopwatch/time-of-day clock and graphically displays the barometric pressure trend.  A Traceable Certificate is provided to indicate instrument traceability to NIST (National Institute of Standards and Technology).

Barometer
Measures barometric pressure from 15.90 to 31.01 in inches of mercury (inHg) with a resolution of 0.03 inHg and from 400 to 1070 millibars (mbar) with a resolution of 1 mbar.  Accuracy is ±0.1477 inHG (± 5 mbar).  Display may be switched to inHg or mbar.

Barometric pressure trend shows present readings and previous 2, 4, 6, 8, 10, and 12 hours in bar-chart format.  Barometric pressure reading is updated every 15 minutes.

Altimeter
The handheld digital unit measures altitude from -500 to 7000 meters and - 1640 to 22,965 feet, with a resolution of 1 meter from - 500 to 1000 meters and a resolution of 2 meters from 1001 to 7000 meters.  Altitude is displayed in meters or feet.  Reading is updated every 2 seconds.  Features a minimum maximum memory for the altitudes reached during any time period, and the altitude trend shows present reading and previous 2, 4, 6, 8, 10, and 12 hours in bar-chart format.

Thermometer
Thermometer displays from -4.0 to 158.0°F and -20.0 to 70.0°C with a resolution of 0.1°, accuracy is ± 1°C. Temperature display is updated every 10 seconds.

Stopwatch and clock
The stopwatch time’s events from 1 second to 99 hours, 59 minutes, 59 seconds.  Resolution is 1 second and accuracy is 0.01%.  Clock displays the time of day to the minute, and shows the day and month.  The clock also features a format of 12-/24 hour timing and an alarm.

Rugged shock-resistant case, compact size (4” x 2 1/2” x 3/4”), and lightweight (3.7 ounces) make this the perfect portable unit.  Unit comes complete with lanyard, batteries, and instructions.
