 红外测温仪型号：OS730K

产品描述

The OS730K infrared temperature gun has 30:1 optics with circle dot laser sighting which allows the user to either measure small objects like components on circuit boards or measure high temperature objects from a safe distance and still with a reasonably small area.

This premium infrared detector has a full set of features including laser targeting, adjustable emissivity, reading hold, min, max, avg, diff, high and low alarms, auto power off, °C/°F, low battery indicator and a Type K thermocouple input with a free thermocouple. The thermocouple input can be used to determine the emissivity of an unknown object for more precise readings.
