Description
Key features
- Contact and non-contact IR thermometer for measuring up close or at a distance, without a ladder
 - Measures temperature from -40°C to 550° C (-40°F to 1022°F)
 - Works with all standard mini-connector type K thermocouples
 - Provides single-point laser sighting
 - Allows easy emissivity adjustment for measuring pipes and other shiny surfaces more accurately
 
Other useful features:
- Features fabric hook-and-loop fastener pipe probe for superheat, sub-cooling, and other contact and ambient measurements
 - Provides MIN, MAX, and DIF functions to help you quickly identify problems
 - Weighs only 12 ounces/340 grams) and is extremely easy to use
