a barometric manometer with 1 pa resolution ?
a barometric manometer with 1 pa resolution ?
(OP)
Why there are gas pressure differential manometers with 1 Pa resolution, but the barometric absolute pressure ones with only 10 Pa (0.1 mBa)resolution ?

have you researched every manufacturer in the world? It seems a bold statement to claim something doesn't exist for sure.

Know the difference between accuracy and precision. but in general if you want high precision (1 Pa0 this only makes sense with high accuracy, which cost $.

So for a "good" gauge with a range of 0 - 100,000 Pa 1% of 100,000 = 1,000. That means that for whatever number you read on the gauge the actual value might be 500 Pa higher or lower than the reading.
If you read 98,532 Pa the true value lies between 98,032 and 99,032.
If you read 1,275 Pa the true value is between 775 and 1,775.
If you read 10 Pa the true value is between -490 and 510
If you read 1 Pa the true value is between -499 and 501
Hopefully you can see the pointlessness of reporting a value of 1 ± 500 Pa
