User manual VAISALA PTB100 DATASHEET

[. . . ] [. . . ] All PTB100 barometers are delivered with a factory calibration certificate, which is NIST traceable. Excellent long-term stability The PTB100 barometer is designed both for accurate barometric measurements at room temperature and for general environmental pressure monitoring over a wide temperature range. The excellent long-term stability of the barometers minimizes or even removes the need for field adjustment in many applications. Ideal for data logger applications The compact PTB100 barometer is ideal for data logger applications because of the low power consumption, selectable external on/off control, practical output voltage ranges and three or four wire connection capability. 112 Vaisala Instruments Catalog 2007 Ref.
