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.

Stik Thermometer Operation Operation Immersion Depth and Usage WCaution To prevent possible damage to the Product or to equipment under test, do not immerse the Probe beyond the maximum immersion depth. This may damage its internal electronics. Allow enough time for the Probe to stabilize before recording measurements. Use the Stability Display to determine when the Probe has stabilized. Probe sensor length is shown in Figure 1. 3 1 2 gjo004.
1551A/1552A Ex Users Manual The minimum immersion depth for the Probe is 3.5 inches in a stirred fluid heat source. It is recommended that you make sure of the minimum immersion depth for the specific application. See Figure 2. • The maximum immersion depth for the 1551A Ex is 2 inches less than the total length. Make sure the last 2 inches of Probe, nearest to the internal electronics of the device, are not put into the heat source.
