Portable chart recorder, Gulton model TR-722. Working.
Dual channel, high speed.
Power cord is included. I used this a number of years ago, to detect
voltage fluctuations.
I checked this out on a 15 v variable supply, and both pens work and
deflect, the burn adjust works, and the paper advances. I've include
the chart sample I just checked both channels of the instrument on.
I went to the Gulton website, and this is still being made. The price
is direct quote only.
Best offer over $15.
sounds like a good deal considering how much i was once told they cost.
why does this thread refuse to list chronologically in my reader? it
always ends up at the bottom of the list. i sorted by date and then
thread like i always do to sort this out and it didn't help.
