VEE GEE Scientific Dial Thermometer 1.75 in Face - Bimetal, No Battery Required

Laboratory and process monitoring thermometers that balance readability and footprint: the VEE GEE Scientific 82-Series Dial Thermometers offer a 1.75-inch face that is readable without magnification but compact enough for instrument panels, equipment ports, and benchtop applications. No batteries — the bimetal coil responds directly to temperature and moves the pointer mechanically, with no electronics between the stem and the reading.

Five models span from general laboratory use (-10 to 110°C, 25 to 125°F) through food safety and process monitoring (0 to 220°F) to high-temperature applications (50 to 550°F). The 82550DG adds a glass face with dual Celsius and Fahrenheit graduation — both scales readable simultaneously on the same dial face.

Features and Benefits

• 1.75 in (44.5 mm) Face — Clear Reading Without Magnification: Larger face than pocket models — graduations are wider apart, reducing reading error at a glance without bending close or using magnification.

• No Battery Required: Bimetal coil thermometry — mechanically operated, no power source, no display failure.

• Wide Temperature Range Options: Five models cover from -10°C to 550°F across multiple scales — general lab, food safety, high-temperature process, and dual-scale applications.

• Dual Scale Option (82550DG): 82550DG features a glass face with both °C and °F graduation on the same dial — eliminates scale conversion errors when working between measurement systems.

• Compact Stem for Tight Clearances: Standard stem diameter fits standard thermometer well ports and insertion fittings common in food processing and HVAC equipment.

Specifications by Model

Laboratory Applications

• Laboratory incubators and ovens — panel-mount temperature monitoring where a continuous reading without power is preferred for reliability

• Food service equipment — fryer, steam table, warming oven, and refrigeration unit temperature monitoring for food safety compliance

• HVAC and building environmental monitoring — duct temperature and return air measurement where battery-free instruments simplify maintenance

• Chemical process vessels — general temperature monitoring at inlets, outlets, and reaction zones where a simple, readable instrument is appropriate

Frequently Asked Questions

What is the difference between 82550 and 82550DG?
82550 has a standard 1.75 in face with a single Fahrenheit scale (50–550°F). 82550DG has a slightly larger 2 in glass face with dual graduation — both Celsius (10–290°C) and Fahrenheit (50–550°F) on the same dial. The glass face on 82550DG provides better scale clarity at high temperatures. Choose 82550DG if you work between °C and °F systems, or if glass face clarity is preferred.

How long is the stem on these thermometers?
The stem length for 82-series dial thermometers is typically 2–4 inches depending on model — shorter than the large 82160 series. Check the product data sheet or contact us for specific stem length per model number.

Are 82220 and 82550 suitable for oven temperature monitoring?
82220 (0–220°F) covers the normal baking range for most food ovens. 82550 (50–550°F) extends to commercial oven and industrial kiln temperatures. Install the stem in an appropriate thermometer port or thermowell — do not expose the dial face to direct heat above its rated maximum.

Quality Assurance

VEE GEE Scientific standard 1.75 in dial thermometers are manufactured from bimetal coil technology with factory-set accuracy and permanently marked faces. Each unit is inspected for graduation clarity and dial pointer alignment before shipment. Covered by a 1-year warranty against manufacturing defects.
