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. Keep the shipping materials until you have made sure that there is no concealed damage.

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:

•4.8 mm x 229 mm (3/16 in. x 9 in.)

•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.

Added features let you tailor the Product for specific applications. These features include:

•±0.05 °C accuracy over full range

•Intrinsically safe (ATEX compliant)

•Display temperature in °C or °F

•Temperature trend indicator

•User-selectable resolution (0.1, 0.01, 0.001)

•Large LCD with backlight
