Handheld type non-contact thermometer of the range -50 to 500oC by the most efficient thermometry technology, especially where contact thermometry is impractical. The twin laser beam helps to exactly pinpoint the diameter of the field of view and performs accurate temperature measurement in oC or oF with fast response in 0.8 second. Mode and setting; *Emissivity adjustment; Press MODE key to enter Пµ (Emissivity) adjustment mode and adjust emissivity with в–І/в–ј keys. (0.10~1.00, 0.01 increment) Peak hold: Maximum or minimum of in-measurement temperature is displayed respectively in MAX, MIN mode.
