Infrared Thermometer

Feature

■ One of the best advantages of a contactless infrared thermometer is its quick response. With SK-8940 you can easily and instantly measure surface temperature in one hand.

■ Applicable for a wide range of temperature from −40 to 500°C. Using a single-point laser marker helps you identify the target at a glance.

■ D:S = 10:1 (D is distance to the object, S is a diameter of a spot circle)

Emissivity is adjustable in steps of 0.01.

■ Certified for PSC, a standard based on Japan's Consumer Product Safety Act, as a class II portable laser device.

■ LCD backlight improves readability in a dark place.

■ Turns off the power automatically if the keys are not pressed for 10 seconds, to prevent from running out the battery even when you forget to turn it off.

■ Automatic hold function keeps the measured value on the LCD for 10 seconds.

■ Traceable calibration available

Description

■ Caution! This device is for industrial use, not for clinical use.

■ What is the distance-to-spot ratio?

A distance-to-spot ratio, which is the ratio of the Distance between the object and the thermometer to the size of the Spot, is preset at D:S = 10:1 for SK-8940. For example, if the distance is 500 mm, a spot circle of diameter 50 mm can be measured. Make sure that the object is larger than the circle.

The spot circle is defined as an area to receive 90% of the emitted energy from the object.

■ Warning: Do not look into the laser marker source or point it on eyes as it may damage eyes.

SK-8940 conforms to the Class II in the Standard for Safe Use of Laser Products (JIS C6802) which is defined as follows: A visible light (wavelength between 400 and 700 nm) with an output level less than 1 mW that a human's protective response can resist.

PSC mark is labeled on the device to prove its quality based on Japan's Consumer Product Safety Act.
