Raytek ST80 Pro Plus hand-held IR temperature sensor | Temperature range of -32 to 760° C; response time of .05 second (95% of reading); weight 320g (11 oz.), these are just a few of Raytek’s Raynger ST80 Pro Plus Infrared Non-Contact Thermometer’s specifications, but its simple operation sequence of point, shoot and read is what makes gathering temperature data easier than ever.
Suited to the most demanding applications, the Raytek ST80 Pro Plus includes innovative features like circular laser sighting, a wide temperature range and 12-point datalogging. The unit is rugged and durable, and includes a jack for an RTD temperature probe. The ST80 can be tripod-mounted for hands-free operation.
Facility maintenance, HVAC systems, food safety, electrical and industrial and marine maintenance are just some of the areas in which the Raytek ST80 can be employed. Powered by 9V alkaline or NiCad batteries, Raytek’s ST80’s target spot sizes are D:S=50:1 at focus point.
Optional nylon holster and RTD contact probe sold separately. |

As the distance (D) from the object increases, the spot size
(S) of the area measured by the unit becomes larger. The relationship between distance and spot size for each unit is listed below. The focal point for each unit is 914mm (36”). The spot sizes indicate 90% encircled energy. |
