Extech 39272 Pocket Fold-Up Thermometer with 4.5-inch Adjustable Probe, −58°F to 572°F, ±1.8°F Accuracy

The Extech 39272 Pocket Fold-Up Thermometer is a compact, foldable contact thermometer with a 4.5-inch adjustable stainless steel probe that delivers fast, accurate readings from −58°F to 572°F.

Small enough to carry in a shirt pocket yet engineered for professional use, this fold-up thermometer combines a locking multi-angle probe, clear digital display, and useful data functions in a lightweight package. It supports both °F and °C, includes Data Hold and Min/Max memory, and conserves battery with an auto-off feature—making it a practical tool for kitchens, HVAC checks, laboratory spot measurements, and field service work.

How does the adjustable probe improve real-world measuring?

The 4.5-inch stainless steel stem pivots and locks at four detent positions (45°, 90°, 135°, and 180°), letting you angle the probe to reach confined or awkward spaces without straining your wrist. The folding design protects the tip during transport and activates auto-off when closed to save battery life.

• 4.5-inch stainless probe that locks at four preset angles for access in tight spots
• Fold-away stem that protects the probe and triggers battery-saving auto-off
• Durable stainless construction for repeated field use and easy cleaning

What accuracy and temperature range can I expect?

This Extech thermometer measures from −58 °F to 572 °F (−50 °C to 300 °C) with a precision rating of ±1.8 °F (±1 °C), and offers selectable resolution to 0.1° for finer readings. That balance of range and resolution makes it suitable for many non-contact-critical tasks where a fast contact reading is required.

• Wide range: −58 °F to 572 °F (−50 °C to 300 °C)
• Accuracy: ±1.8 °F (±1 °C) for reliable spot checks
• Selectable 0.1° or 1° resolution for clearer readouts when needed

Which display and data features make it easy to use on the job?

The large LCD shows temperature clearly at a glance and responds quickly to changes. Built-in functions like Data Hold and Min/Max let you freeze a reading or review extremes during a measurement session, simplifying documentation and troubleshooting.

• Large, fast-reading LCD for rapid visual confirmation
• Data Hold to lock a reading for recording or photo documentation
• Min/Max memory to capture temperature swings without continuous monitoring

How portable and rugged is this thermometer for field work?

Weighing about 2.5 ounces and roughly the size of a large pen when folded, the Extech 39272 slips into pockets or tool kits easily. It includes a wrist strap and runs on a single AAA battery, offering long practical run time with an intelligent auto-shutoff to extend battery life.

• Compact, pocket-friendly size for everyday carry
• Includes wrist strap and single AAA battery for immediate use
• Auto power-off reduces battery drain when folded or idle

Who is this for? Professionals and hobbyists who need reliable contact temperature checks without bulky gear will find the Extech 39272 ideal. Chefs verifying final internal temperatures, HVAC and maintenance technicians checking system components, lab technicians performing quick spot checks, and field service personnel who value portability all benefit from its adjustable probe, readable display, and practical data features. It’s not meant for continuous monitoring or intrusion into sealed systems, but it excels at fast, accurate spot measurements wherever a compact, dependable probe thermometer is needed.
