The one I have comes w/ the riserbond 1205c. I assume you could get one from them. I agree that accuracy is a long shot using one. The only way Ive been able to document faults is to disco the plant. Now what Ive done in the past is carry RG11 and f81 to pin connectors to minamize down time when Im running the plant out. See if this the customer will allow this. Good luck and let me know if Ive been helpful.
