Most low-cost digital thermometers have fairly short probes. They're great for the pocket but can be frustrating when you need a longer reach! Our long-stem model features an 8-inch probe that is perfect in lab work, food production, and countless applications where you need longer immersion depth. It includes a 0.137" (3.5mm) diameter pointed probe for added durability with reasonably fast readings. A sheath is supplied to protect the stem in storage or transport.

  • The RT304-8 features accuracy to ±0.9°F and an upper range to 392°F. It's sealed from moisture with an IP67 water-resistant rating and built to last in daily commercial use. With an extra long battery life of 5,700 hours, you'll go years between battery changes.

    The Max/Min function stores high and low temperatures for easy recall and won't "auto-off" right in the middle of use. The scale is switchable between °C and °F.

    Every well-equipped thermometer kit should have one of these!
