VICTOR 302B Handheld Infrared Thermometer

VICTOR302B Infrared thermometer with Range -32℃～3800℃ Handheld thermometer

I. Brief Introduction to the Product

The instrument is a professional hand-held non-contact infrared thermometer, and is featured by convenient use, strict design, high measurement accuracy, broad temperature measurement range, and with HEIMANN infrared temperature probe, the product has high measuring precision and more stable performance etc. It has the functions like laser aiming, LCD backlight, over-temperature alarm and automatic shutdown. When being used, the product can measure the temperature of objects quickly and accurately only with the probing window aiming at objects.

II. Basic Operating Principles

All objects whose temperature is higher than absolute zero degree will transmit a certain proportion of infrared radiation energy according to their own temperature. The size and wavelength-based distribution of radiation energy have very close relationship with its surface temperature. According to this theory, we may obtain the accurate temperature of a measured object by accurately measuring its infrared transmission energy.

IV. Application Method

• Safety clauses

1. The product shall be used carefully when the laser beam is opened;
2. Don’t make the laser beam aim at the eyes of people or animals;
3. Don’t make the laser beam reflected into people’s eyes by aiming them at the surface of objects;
4. Don’t make the laser beam aim at any explosive gas. 

• Measuring steps and methods

1. In order to obtain precise temperature value, the thermometer shall be used 10min after mounting of battery; if the product is moved to a new environment (new place), it shall also be used after 10min.

2. After the detection window is made aiming at the measured object, and the measuring key on the handle is moved, the thermometer will be started automatically. When sending out the prompt sound “beep”, the product will display the measured result.

Note: Before measurement, the emissivity of the object to be measured shall be selected, and meanwhile, the measuring distance shall be adjusted according to the size of the object to be measured.
