IMPORTANT NOTES

Obstruction of the vent hole will compromise performance, and must be avoided. Do not remove label.

Adequate free volume should be provided below the sensor to ensure full performance.

All tolerances ±0.15 mm unless otherwise stated.DO NOT solder to pins.

All performance data is based on conditions at 20ºC, 50% RH and 1013 mbar.
