Testo Digital Manometers 506-3 vs 510
Does anyone have any experience with either the Testo 506-3 or the 510? Any preferences, or suggestions on which is more usefull?
My main use will be taking gas pressure reading, with a secondary use of airflow and static pressure readings.
Any and all help is appreciated!
The 506 is no longer manufactured, so it is not an option unless you find one at a supply house. The 510, its replacement actually replaces two Testo manometer, the 506-2 and 506-3. It is a duel range with a very stable sensor. It can be used up to 40" and has a resolution low enough to measure airflow with a Pitot tube. It will also measure pascals through the entire range. It is a substantial improvement over the 506-3. The entire pocket line is pretty slick. It has a magnetic back, and the top cover protects the display in your tool box. It also uses a temperature compensated pressure sensor, so it is very accurate.
Display in Pascal possible over entire measurement range
0-40 inH20 range
Accuracy: ±0.03 hPa (0 to 0.30 hPa) / ±0.05 hPa (0.31 to 1.00 hPa)
Magnetic rear permits free-hand work
Flow velocity measurement with Pitot tube (Pitot tube not included)
Air density compensation (adjustable)
Protective cap for safe storage
Including wrist strap and belt holder
Switchable units: hPa, mbar, Pa mmH2O, mmHg, inH2O, inHg, psi, m/s, fpm
Does that mean that if I take it from my relatively cool truck up into a blazing hot attic in the summer, or my relatively warm truck into a freezing cold attic in the winter, I won't have to constantly pull the hoses off and rezero it while it is changing temperature.

Just about, lol.

Check out this post of mine from April 2005.
The Testo 435 multi function meter, that came out in 2006, satisfies all of those criteria!
Including the upper range of price I said I was willing to pay, lol.
Maybe you should have set your upper price lower and it wouldn't cost so much
Reality is merely an illusion, albeit a very persistent one.
