Not to hijack the thread but I just got done writing a somewhat lengthy email to OSI letting them know of mine and others' disatisfaction with the THGR968 sensor and it's problems.
To my surprise I have gotten several emails back telling me that they will pass this on to the senior engineers for invesitgation. I know, I know , don't start yet witht the usual "Believe it whan I see it" routine. I am a little more curious this time with the unusual quick responses to my emails. I also let them know about this site and encouraged them to look at the forum for the complaints and problems we have seen with this sensor (THGR968).
FWIW,
Jim
