Introduction; Features - Fluke 1551A Ex User Manual

Introduction

The Stik Thermometer (the Product or the Probe) is a precision digital thermometer that
can be used as an alternative to mercury liquid-in-glass (LIG) thermometers. It can also
be used as a reference standard for other types of digital or analog thermometers. Because
of its intrinsically safe certification, it can be used in many of the same hazardous
locations as analog thermometers.
When you receive the Product, check that it is intact. The batteries are factory installed.
Keep the shipping materials until you have made sure that there is no concealed damage.

may only have to change the batteries a few times a year.
