Tel-Tru BQ225 barbecue thermometer — 2" aluminum dial, 2.5" stem, 100–500°F range, stainless steel body

Tel-Tru BQ225 is a compact back-mount barbecue thermometer with a 2-inch aluminum dial and a 2.5-inch stem, designed to read 100–500°F for grill and smoker temperature monitoring.

Built for backyard barbecues and mobile cooking rigs, the Tel-Tru BQ225 offers a rugged stainless-steel body, a clear glass lens, and a threaded bushing for secure panel or lid mounting. Its 100–500°F range covers common grilling and smoking temperatures, while the blunt tip and 1/4"-20 connection make installation straightforward in lids or doors that accept a 1/4" diameter hole. The dial’s aluminum face resists the elements and provides easy-to-read markings at a glance.

How accurate and durable is this Tel-Tru thermometer?

The BQ225 uses a quality bimetal sensing element housed in 304 stainless steel for corrosion resistance and long service life. Accuracy will be typical of mechanical barbecue thermometers — reliable for monitoring general grill and smoker conditions rather than lab-grade precision.

• 304 stainless-steel construction for rust resistance
• Glass lens protects the dial and improves visibility
• Aluminum dial with clear 100–500°F markings for quick reads
• Back-mount design keeps the stem and wiring tidy inside lids or panels

How do I mount the BQ225 in my grill or smoker?

Mounting is straightforward: the gauge uses a 1/4"-20 threaded bushing with a wing nut for secure attachment through a 1/4" diameter hole. Position the dial on the outside of the lid or panel and tighten the wing nut from the inside until the unit sits flush and stable.

• Requires a 1/4" (0.25") diameter hole for installation
• 1/4"-20 threaded bushing and wing nut for tool-free tightening
• Back-style mount keeps the dial snug against lids or doors
• 2.5" stem length suitable for thinner lids or panel mounts

What temperatures does the dial show, and what cooking tasks is it suited for?

The aluminum dial displays temperatures from 100 to 500°F, covering low-and-slow smoking through high-heat searing ranges. It’s ideal for monitoring ambient grill or smoker temperatures rather than internal food temperature readings.

• Range: 100–500°F to cover smoking, roasting, and searing
• 2-inch dial sized for legibility at typical viewing distance
• Blunt stem tip designed for ambient heat sensing inside lids
• Not intended as a direct probe for internal meat temperature

What are the key physical specs I should check before buying?

Confirm your grill or smoker has a 1/4" diameter hole and sufficient panel thickness for the 1/4"-20 bushing to engage. The 2-inch face and 2.5-inch stem mean the thermometer sits close to the mounting surface — perfect for lid installation but too short for deep chambers if you need the sensor centered.

• Dial diameter: 2 inches for compact mounting
• Stem length: 2.5 inches from the back-mount body
• Connection type: 1/4"-20 threaded bushing with wing nut
• Tip type: blunt — designed for ambient temperature sensing

Who is this for? The Tel-Tru BQ225 suits backyard grillers, food trucks, and small smoker owners who want a dependable, low-maintenance dial gauge to monitor chamber temperatures. Choose this model if you need a corrosion-resistant, back-mount thermometer with a readable 100–500°F dial and a compact 2.5" stem for lid or thin-panel installation. If you require probe-style internal meat readings or deeper chamber reach, consider a longer-stem or probe thermometer instead.
