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!

What is an IP Rating?
An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress. Click for a table of IP Rating values.
IP66 - No ingress of dust (6); Protected against strong jets of water e.g. for use on shipdecks - limited ingress permitted (6).
