Barometer, altimeter, thermometer, stopwatch, and time-of-day clock—all in the palm of your hand!
Handheld Digital Barometer measures altitude, temperature, and barometric pressure. Also has a stopwatch/time-of-day clock and graphically displays the barometric pressure trend.
Traceable® to NIST for Accuracy
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST.
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 reading and previous 2, 4, 6, 8, 10, and 12 hours in bar-chart format. Barometric pressure reading is updated every 15 minutes.
Handheld digital unit measures altitude from -500 to 7000 meters (-1640 to 22,965 feet), with a resolution of 1 meter from -500 to 1000 meters (-1,640 to 3,281 feet) and a resolution of 2 meters from 1001 to 7000 meters (3,284 to 22,965 feet). 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 displays from -40.0 to 158.0°F and -40.0 to 70.0°C with a resolution of 0.1°, accuracy is ±1°C. Temperature display is updated every 10 seconds.
Stopwatch and clock
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 date 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 inches), and light weight (3.7 oz) make this the perfect portable unit. Supplied complete with lanyard, 2 batteries, and instructions. Replacement battery Cat.No. 291-1005.
