Barometer, altimeter, thermometer, stopwatch, compass, 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, compass and graphically displays the barometric pressure trend. 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 (National Institute of Standards and Technology).



Measures barometric pressure from 8.85 to 32.45 inches of mercury (inHg) with a resolution of 0.01 inHg and from 300 to 1100 millibars (mbar) with a resolution of 1 mbar. Accuracy is ±8 mbar at tested points. Barometric pressure trend shows current reading and previous 2-, 4-, 6-, 8-, 10-, and 12-hours in bar-chart format. Barometric pressure reading is updated every 15 minutes.


Measures altitude from –2296 to 29520 feet (–700 to 9000 meters), with a resolution of 0.1 from –500 to 999.9, 1 otherwise. 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 12-hours. May also be manually adjusted to a known altitude.


Thermometer, stopwatch/timer, clock, and compass

Thermometer displays from -10 to 60 °C/14 to 140 °F with a resolution of 0.1°. Accuracy is ±1.5°C. Temperature display is updated every minute. Stopwatch times events from 1 second to 23 hrs, 59 min, 59 sec. Countdown alarm timer counts down in from 1 second to 23 hrs, 59 minutes, 59 seconds. Resolution is 1 second. Clock displays the time of day and shows the date, month, and day of week. The clock also features a format of 12/24-hour timing and an alarm. Compass feature displays real time direction in whole circle bearing, or compass bearing. Rugged shock-resistant case, compact size 3-3/4 x 2-3/4 x ¾-inches, and light weight 3-1/2 ounces make this the perfect portable unit. Supplied complete with lanyard, 2 batteries, and instructions.

Please note: The aforementioned A2LA accreditation belongs to the manufacturer, not Thomas Scientific.
