Rated 5 out of 5 by from Fire Loss Testing Excellent tool to log temperature and interval data in field fire loss analysis. The results of fire loss testing help to understand the likelihood of ignition, ignition sequence, and fire spread beyond the point or area of origin. The 54IIBs accuracy (0.05% +/-) makes it a reliable meter that can withstand scrutiny in litigation.

Rated 4 out of 5 by from Good relyable performance We use many of these within the facility and field service for many years. They remain calibrated and can withstand a variety of applications. Only issues are the corners of the screens crack when dropped, sockets for t-couples do not make consistent contact, and unit is not water resistant.

Rated 4 out of 5 by from Very Dependable tool I purchased 4 Temp Meters for my plant It work well and very dependable. Great price and does what it was designed to do. I would definitely repurchase FLUKE brans products again. I would also recommend FLUKE to my co-workers and friends.

Rated 3 out of 5 by from we have 12 The units function well in a tough industrial environment. Our only issue is that after several years the battery terminal connectors become brittle and break off and we cant find replacements....

Rated 3 out of 5 by from seems to work well but not complete I just purchased this item. It seems to work well but the features are difficult to find on the display. Also, I bought it from McMaster carr and it didn't come with the IR device to get the data off of it nor did it come with the software so I am not sure why the additional memory/feature to store 500 data points cost me 250 bucks more because I cannot gain access to the data.
