Victor Infrared Thermometer – -32°C to 1650°C, 50:1 D:S, Adjustable Emissivity, Non-Contact Temperature Measurement 302B 303B 306B 307C 308D 310C

Six Models Cover Every Temperature Application

• The Victor 300 Series offers six dedicated infrared thermometer models, each designed for specific temperature ranges and use cases:
  • 302B – (-32~380°C) Entry-level for HVAC and electrical
  • 303B – (-20~550°C) General purpose industrial
  • 306B – (-50~700°C) Wide range with adjustable emissivity
  • 307C – (-20~800°C) Higher accuracy ±1.5%
  • 308D – (-30~1150°C) High-temperature industrial
  • 310C – (-20~1650°C) Extreme heat applications like metal processing
• No matter your maximum temperature requirement, there is an infrared thermometer in this series that fits your exact needs.

Extreme Temperature Ranges for Versatile Use

• From -50°C (306B) for cold storage and refrigeration diagnostics up to 1650°C (310C) for foundries, kilns, and metal forging.
• This infrared thermometer series spans a staggering 1700°C of measurement capability.
• Fahrenheit equivalents provided for all models – convenient for US and international users alike.

Superior Distance-to-Spot (D:S) Ratios

• Entry models (302B/303B/306B): 12:1 D:S – suitable for standard electrical panels and HVAC vents.
• Mid-range (307C): 20:1 D:S – allows you to measure smaller targets from farther away.
• High-end (308D/310C): 50:1 D:S – the ultimate infrared thermometer for measuring tiny or distant targets like overhead power lines, moving machinery, or hazardous zones.
• With a 50:1 ratio, you can measure a 1-inch target from 50 inches away – safe and precise.

Outstanding Accuracy Across the Line

• 302B/303B/306B – ±2.0°C or 2% – reliable for most field tasks.
• 307C/308D/310C – ±1.5°C or 1.5% – laboratory-grade accuracy in a rugged infrared thermometer.
• No other infrared thermometer series at this price point delivers such consistent, trustworthy readings.

Adjustable Emissivity for True Surface Temperature

• Basic models (302B/303B): Fixed 0.95 emissivity – perfect for most organic materials, painted surfaces, and electrical gear.
• Advanced models (306B/307C/308D): 0.1 to 1 adjustable emissivity – critical for measuring shiny metals (low emissivity) or high-emissivity materials like ceramics and asphalt.
• 310C – 0 to 1 fully adjustable emissivity – maximum flexibility for the professional user.
• An infrared thermometer without adjustable emissivity can give wildly inaccurate readings on reflective surfaces – Victor gives you control.

Fast 0.5 Second Response Time

• Measuring time: 0.5 seconds on the 302B (and comparable across the series).
• Point, pull the trigger, and get an instant reading – this infrared thermometer keeps pace with fast-moving production lines or quick-scan troubleshooting.

8~14μm Spectral Response

• Optimized spectral range for general-purpose non-contact temperature measurement.
• This infrared thermometer cuts through atmospheric interference for accurate readings at distance.

High 0.1°C / 0.1°F Resolution

• All models display 0.1-degree resolution – no guessing between whole degrees.
• Detect subtle temperature changes like a 0.3°C rise in a bearing or a 0.5°F drop in an air vent.

Compact to Heavy-Duty Physical Options

• 302B (143×93×37mm, 105g) – ultra-light infrared thermometer for daily carry.
• 303B (147×92×43mm, 168g) – still compact, slightly more rugged.
• 306B (200×141×60mm, 200g) – larger body for gloved hands.
• 307C/308D/310C (201×147×60mm, 270g) – heavy-duty industrial infrared thermometer with tool case protection.
• Choose the form factor that matches your work environment.

Professional Packaging & Accessories

• Blister packaging (302B/303B) – retail-ready for store displays.
• Tool case included (306B/307C/308D/310C) – protects your infrared thermometer on job sites and in truck beds.
• Standard accessories: Manual, battery, and tool case for applicable models – everything you need out of the box.

9V Battery Power – Globally Available

• Powered by a standard 9V battery – no special rechargeable packs to lose or proprietary chargers to misplace.
• Replace anywhere in the world. This infrared thermometer keeps working when specialty tools fail.

Non-Contact Safety for Live & Hazardous Targets

• As a true infrared thermometer, the Victor 300 Series measures temperature without touching the target.
• Safe for:
  • Live electrical panels – no arc flash risk
  • Rotating machinery – bearings, motors, conveyor rollers
  • Extreme heat – furnaces, exhaust manifolds, steam lines
  • Remote or dangerous locations – overhead lines, chemical vessels
• Keep your distance and still get accurate readings.
