• Hand-held unit measures altitude, temperature and barometric pressure
• Barometric trend graph delivers present and previous 2/4/6/8/10 and 12-hour readings in bar-chart format
• Barometer pressure readings are updated every 15 minutes

Barometer, altimeter, thermometer, stopwatch, compass, and time-of-day clock-all in the palm of your hand Handheld Digital Barometer 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 Control Companys ISO/IEC 17025 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

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.

Rugged shock-resistant case, compact size, and light weight make this the perfect portable unit. Supplied complete with lanyard, 2 batteries, and instructions. Replacement battery Cat. No. 350-16678.
