Introduction
The Stik Thermometer (the Product) 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.

Features
This section tells you about the features of the Product.
The 1551A Ex Probe contains a fast-responding thin-film sensor that makes accurate
measurements quickly and with minimal immersion depth. The Probe is available in
three versions:

6.35 mm x 305 mm (1/4 in. x 12 in.)
6.35 mm x 508 mm (1/4 in. x 20 in.)
The 1552A Ex Probe contains a stable, wire-wound platinum sensor with a
6.35 mm x 305 mm (1/4 in. x 12 in.) length sheath.
A rotatable probe mount lets the display module be turned horizontally or vertically.
A unique feature of the Product is the trend indication arrows. You can configure the
arrows to show when the measurements are adequately stable to record a result.
The auto-off feature gives extended battery life of 300 hours maximum. The typical user
may only have to change the batteries a few times a year.
