Traceable® Products Traceable® Digital Barometer Model 4198

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 (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 ±0.2363 inHg (±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. Altimeter Measures altitude from -500 to 7000 meters (-1640 to 22,965 feet), with a resolution of 1 meter or 1 foot. 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 -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 times 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 (3-2/3 oz.) make this the perfect portable unit. Supplied complete with lanyard, 2 batteries, and instructions. Replacement battery Cat. No. 1005.
