Lightweight, compact, and easy to use, the Raynger ST can safely measure hot, hazardous, or hard-to-reach materials without touching, contaminating, or damaging the material's surface.
Accurate temperature measurement in seconds!

ST2: Measure temperature in seconds with this basic model. Affordably priced, the ST2 is our most popular unit for professionals who need to measure up to 400°C (750°F).

ST3: New! This model adds laser sighting, which helps pinpoint the target being measured. This feature helps the user aim at surfaces that are hard to reach or see.

ST6: In addition to the features included in the above units, this model also has high/low alarm, MAX, MIN, DIF, and AVG temperature settings, an expanded temperature range, and adjustable emissivity, which compensates for reflective surfaces such as polished metals.

ST8: New! This new model has all the features listed above plus an expanded temperature range of -32 to 540°C (-25 to 1000°F) and improved optics that allows the user to measure smaller objects from farther away. This is great news for HVAC or facilities maintenance professionals who need to measure ceiling and duct temperatures from a distance.
