| Hand-Held Barometer / Altimeter |
| Model 230-355 |
The Model 230-355 Handheld Barometer
& Altimeter combines accurate pressure sensing with the power of microprocessor-based
computations to provide instantaneous pressure and altitude readings.
A combination of small size, digital display, versatility, and high accuracy
make it ideal for field measurements or as a portable pressure reference.Keypad
controls provide access to the operating functions. Pressure or altitude
may be displayed in a variety of units. The LCD display shows the data
output and operating mode. This instrument measures atmospheric pressure
very accurately, to within 0.01" Hg. Altitude is computed using the
U.S. Standard Atmosphere of 1962. The altitude function used with the
min/max and tare make the unit useful as a surveyors tool.Airport
altimeter setting is computed and displayed based on an entered altitude.
Change in pressure or altitude can be continuously displayed. The device
is temperature compensated over its operating temperature range.The
316 stainless steel pressure sensor has extremely low sensitivity to shock,
vibration, acceleration, and changes in orientation or temperature, yet
features high sensitivity to pressure variations. Each unit comes with
a certificate of calibration traceable to NIST. |
