Tpi 775 has served me well for 10 years. Finally broke down, sending it in for repair and purchased another as replacement 👍

Tge TPI 720b sucks

This thing is junk!

How long does the O2 sensor last ? How much it costs to replace it ?

Can you pls share the video while it's working at proper system And can be use for exhaust gas analysis as well?

Does it need calibrating? And if it does, how often? Thanks. Nice video.

It doesn't fail test if the pressure has changed outwith tolerance in between start/end. , only gives the initial v final reading as a check.

Not many review's about on this but i thought i would give it a try... works great, might try the analyzer when mine packs up

Good vids! 😁 You’ve got a new subscriber! Why don’t you use PromoSM!!? You should use it to promote your videos!

What's the permissible drop with a digital monometer?

Shouldn't the auto test be set at 0.2 perceptible drop!? As its a digital gauge! 0.25 for a water gauge! Was this an error in the video or if not can the perceptible drop tollerences be changed in settings?

Does it record standing and working pressure too please?

What is the cost of unit
