INTRODUCTION 1
Introduction CHAPTER 1
The CheckMate™ is the next evolution in handheld corrosion monitoring instruments. It
is capable of reading all Corrosometer®(electrical resistance) corrosion probes with an
enhanced resolution of 0.1 probe divisions (0.01% probe span). The CheckMate™ also
features a reduced measurement cycle while still maintaining high accuracy. As with its
predecessors, this portable unit has built-in memory that stores readings for later retrieval,
however the CheckMate™ can store readings for up to 204 individual probes, with 10
readings per probe. Furthermore, the CheckMate™ makes transferring its stored data to
a PC a much simpler process than before, using the included Corrdata®CSV program.
