Analog Barometer - Vaisala PTB101
For WMO-standard accuracy and stability we use PTB101 to measure Barometric Pressure in many of our Electronic Weather Stations.
For WMO-standard accuracy and stability we use PTB101 to measure Barometric Pressure in many of our Electronic Weather Stations.
This is suitable for a variety of atmospheric pressure monitoring applications.
Has excellent stability and remains accurate over its full working temperature range.
It's ideal for data logger applications because it has low power consumption, selectable external on/off control, practical output voltage ranges and three or four wire connection capability.
Come with a NIST-traceable factory calibration certificate.
