Chemglass hotplate controllers - "shorted" sensor
I have two of these plates made by Chemglass that work fine..... as long as the controller works. Well, yesterday the controller started throwing a
code that tells me to replace the $150 temperature probe, it thinks it's shorted apparently.
I'm looking, but is there anyway to run these plates without the controller/temp probe? When I bought them, I only got one controller - sure would be
nice if both plates would function w/out the (convenient when it works) temp controller.
Maybe I could attach a different thermo-couple? But then there's calibration issues I guess.
Any work-around suggestions welcome, I can afford the sensor, just feel like I could work fine w/out it, plus I'm not sure they'd give me the time of
day without a corp. acct.

If you say what the model number is, or include a link to the item, people might be able to help you. Without that, we can't help much.

I have a couple Chemglass stirrer hotplates. On the back there is a round plug receptacle. As you look at it there are 5 "holes." Hole number 1 is in
the 1 o'clock position. If you jumper holes 3 and 5 with a piece of wire you should be able to use the device as a normal stirrer-hotplate. When new,
these units come with a "shorting plug" attached but these are usually lost along the way. I recently purchased one of these units as a "parts only"
sale ($25) and with the jumper all worked fine. The stirrer will work without the jumper but the hotplate will not. Good luck.

There really aren't any markings on the plates and only "etc" on the controller. If there are model numbers (seems there would be, as these plates
aren't identical), I've yet to find them.
Anyway it's a moot issue, as I found the jumpers inside what I thought were just covers for protection, so problem is manageable and now I have two
plates working.
Thank you AvBaeyer!
