TRU-FLATE tire pressure guages are made by Stant. If you search the Web for
"Tru-Flate" you will find several stores that sell them. I have been using a
digital tire guage (like the one originally suggested on Soh Chio's site) up
until now to calibrate my pressure sensor (which I bought on e-Bay), but the
TRU-FLATE dial looks a better approach. I have also been using the RCX and a
pressure sensor to measure the effectiveness of different pump designs. I'll
post the results when I have finished. I think Soh Chio's Web site is great!

BTW I was just browsing your website (really great site BTW) and had a
question...do you know what type of pressure gauge you used on the creation
on the main page? I've been trying to find an air pressure measurement
device which works with the Lego pneumatic system for some time now but have
had no luck...

Well, the markings say "TIRE PRESSURE GAUGE" at the top and "TRU-FLATE"
at the bottom. It reads to 60 psi. No other markings to indicate its
manufacture.

It came courtesy of John Barnes together with the pressure sensor. The
inlet has been specially modified with a nozzle that will nicely fit the
Lego pneumatic tubing.

I think it is better than the Monkey Grip digital tire pressure gauge
that Michael Gasperi is using as it can provide continuous readings. But
I wouldn't rely too much on it as its accuracy is far short of the
silicon pressure sensor.

(...) Thanks for the identification of the tire pressure gauge. I reckon the stores will soon be doing a brisk trade in them. But I would hesitate to use the word *calibrate* - the pressure sensor is a far more delicate device than the tire gauge. (...)
