Panel meters and process thermometers need to be readable from a distance — a 1.75-inch face requires standing close and looking carefully, which is impractical for monitoring a tank, walk-in cooler, or processing vessel from an operating position. The VEE GEE Scientific 82160 Dial Thermometer has a 3-inch (76 mm) face that is readable at a glance from several feet away — making it appropriate for panel mounting, tank installation, and equipment monitoring where a large, immediately readable display is the priority.
Available in 6 in (82160-6) and 12 in (82160-12) stem lengths, both covering the -40 to 71°C / -40 to 160°F range in both Celsius and Fahrenheit scales simultaneously. Also available as the 82070-6 and 82070-12, reading 0 to 100°C in °C only. Battery-free bimetal operation. The 6-inch stem suits surface-mount or shallow installations; the 12-inch stem reaches deep into tanks, wells, and process vessels.
Features and Benefits
3 in (76 mm) Face — High Visibility from a Distance: Large 3-inch dial is readable from several feet away — ideal for monitoring tanks, baths, ovens, and process equipment where the thermometer is mounted and read remotely.
6 or 12 in Stem Options: 82160-6 has a 6-inch stem for surface-mount and shallow well applications; 82160-12 has a 12-inch stem for deep well and tank insertion. Same face, same range, different installation depth.
-40 to 71°C / -40 to 160°F Range: Covers the most common refrigeration, cold storage, and moderate process temperature monitoring range in a single instrument.
No Battery Required: Bimetal coil — always-on, no power required, suitable for continuous monitoring without battery replacement.
2°F / 1°C Resolution: Standard resolution for general process and food safety monitoring applications where ±1°C accuracy is sufficient.

Laboratory Applications
Walk-in cooler and refrigerated display case temperature monitoring — panel-mount with 3 in face readable without opening the door or approaching the equipment
Water bath and tank temperature display where a large, continuously visible reading is required without digital instrument investment
HVAC duct temperature monitoring with the 12-inch stem (82160-12) for insertion into supply or return air ducts of any standard size
Industrial process vessels and tank thermowells where the thermometer face is mounted externally and must be readable from an operator workstation
Frequently Asked Questions
Which stem length should I choose — 6 in or 12 in?
Choose 82160-6 (6 in stem) for surface probe applications, shallow wells, or installations where the probe needs to penetrate only a few inches into the medium. Choose 82160-12 (12 in stem) for deep tank installations, duct measurement, and thermowell installations where the stem must reach the measurement zone inside a vessel or duct.
Do both models read both Celsius and Fahrenheit simultaneously?
Yes — both 82160-6 and 82160-12 have dual C and F scales on the same 3-inch dial face. Both scales are permanently engraved and read at the same time, eliminating the need to convert between temperature systems. The 82070-6 and 82070-12 read in °C only, 0 to 100°C.
What is the accuracy of the 82160 series?
Bimetal dial thermometers of this size typically achieve ±2°F / ±1°C accuracy at mid-scale under stable conditions. For regulatory compliance or calibration-traceable measurement, verify accuracy with a reference thermometer and document the offset. Contact VEE GEE Scientific for detailed accuracy specifications.
