Key Benefits

For Harsh Environments
The PTB210 is ideal for outdoor installations and harsh environments. Operate in a wide temperature range, and the electronics housing provides IP65 (NEMA 4) standardized protection against sprayed water.

Excellent Hysteresis & Repeatability Characteristics
The PTB210 barometers use the Vaisala BAROCAP® Sensor, a silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure applications.

Several Pressure Ranges
The PTB210 barometers are designed for various pressure ranges. They are available in two basic configurations: serial output for 500 … 1100 hPa and 50 … 1100 hPa and analog output with different scalings between 500 … 1100 hPa.
