TEMPERATURE PROBE

I need a temperature probe for Microm HM520 or HM525  ( part number 330320). The probe is not available from the thermo fisher scientific. Does anybody know the datasheet for this probe, so I can find a compatible one or have it remanufactured?

Epredia is now the manufacturer of this line of products. Have you checked to see if it is available from them?

The sensor is almost certainly the same (maybe different cable length) as the defrost sensor - measure the resistance of that sensor, note the temperature inside the cabinet, and then consult an RTD resistance chart to find the correct type. You'll then be able to buy a compatible sensor. Omega Engineering would be a possible source.

Typically at room temperture the resistance of the temp sensor probe would be in the neighborhood of 12 to 15 Ohms.
