Im looking for a TOHO TRM20 model but it looks this part is already obsolete. Any recommendation please
The TRM20 looks to be the base model number. Here is the part number breakdown I was able to find for the full part numbering.
At this time we do not have a Temp recorder in our system from TOHO.
Here is a link for TOHO’s contact information to inquire about their paperless recorders.
