  Make sure the last 50 mm of probe, nearest to the internal electronics of the device, are not put into the heat source.

The Best Alternative to Mercury Thermometers

The Fluke Calibration 1551A-20 "Stik" Thermometer is the new "gold standard" of industrial temperature calibration. Its stainless steel probe and digital readout are fixed together and calibrated as a system. Its large backlit LCD display can rotate 90 degrees which ensures readability from any angle. It also features a user-adjustable stability/trend indicator that signals when the temperature is steady enough for an accurate reading to be taken. The device includes a user-programmable auto-off feature that can prolong the typical battery life to as much as 300 hours. A low-battery indicator and a stop-measure function are also incorporated to prevent inaccurate measurements due to a depleted battery. Plus, you can easily and accurately calibrate the 1551A with a simple three-point calibration function.

"Stik" Thermometer Series

Whether working outdoors in environments where potentially explosive gases may be present or on the floor of a processing plant, the "Stik" series are intrinsically-safe, battery operated, portable reference thermometers designed to go where you work. There are two models to choose from, the 1551A (-50 C to 160 C) or 1552A ( -80 C to 300 C) each with varying probe versions.

The thermometer's 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.)

With a superior probe design combined with electronic functions that assist accurate measurement, the "Stik" Thermometer surpasses the capabilities of other digital thermometers.

Data logging options: append "–DL" to your model number of choice to configure your “Stik” Thermometer with the data logging option.
