SECTION 1 INTRODUCTION

The OMEGA®Model K-79 Series Pocket Thermometer is a small,
mechanical (non-electronic) thermometer that is accurate, rugged and light
in weight. The clear, easy to read 1" dial has a pointer that is directly driven
by the sensitive bi-metal helix coil located in the shaft. The 0.142" diameter,
5" stainless steel probe has a needle tip for penetrating semi-solid materials
such as fruits and meats. The pointed probe is supplied with a tubular
pocket case complete with a pocket clip and holder loop. (See Figure 1)

SECTION 3 OPERATING INSTRUCTIONS

For accurate temperature measurement, you must immerse the stem at
least 2" in a liquid, 3" in a semi-solid (i.e. meat), and 4" in a gas (i.e. air).
You should leave the stem in the material being measured for a time
period long enough to achieve a stable reading. This usually is about 5
“time constants”, or in the case of a liquid, about 20 seconds. (NOTE:
time constant is defined under SPECIFICATIONS)

For measuring at high temperatures, the holder loop can be used by
inserting the stem through the loop, making the case a holder for the
thermometer, to avoid excessive heat exposure to the hand.

When inserting the thermometer into semi-solid materials, such as
frozen foods, soils, meat, fish, fruit, etc., hold the stem firmly and insert
