Amazon has them for $7.99. Polder Probe This link does not get you to Amazon through TVWB. So go look at it and make sure it is what you want. Then use the TVWB link to go to amazon to buy it. Support your website.
Make sure you order the correct probe for your particular model polder. There are several different probes.I have the original Polder model 362-90 and the probe for $7.99 at Amazon shown in the above post does not work. If you have the original shown here polder 362-90 then you need this probeprobe 364
Thx for the tip. I have two monitors, non-Polder. However, one of the monitors looks exactly like the original Polder (with the exception of a different brand name and color). How does one find out which probe to purchase?
