The testo 830-T2 has laser function and 12:1 optical resolution, which is suitable for industrial or inlet and outlet temperature measurement. The advantages of using infrared thermometer to realize non-contact and rapid measurement of temperature (2 measurements per second) are as follows: High and high resolution processor (resolution 0.1℃) Even at medium distances, 12:1 optical resolution ensures accurate measurement. Two point laser is used to confirm the tested area You can customize two limits Audible and visual alarm when the limit value is exceeded Minimum/maximum value display, holding function for data recording Handgun design for single hand operation, Clear backlight display, K-type thermocouple can be connected externally The measurement rate of testo 830-T2 is greatly improved, and it can provide two measurement results per second. More measurement tasks can be completed quickly and efficiently. In addition to infrared measurement, the testo 830-T2 can also choose contact measurement, and only K-type thermocouple probe needs to be connected. provides you with probes that meet different applications, such as spring probes for rapid measurement of temperature, air probes or immersion/penetration probes (for liquid and semi-solid measurement). The emissivity of the infrared thermometer can be adjusted independently, and the emissivity can be set according to the of different measured materials. For the temperature measurement of untreated low emissivity , reflective sticker can be to facilitate infrared measurement. Color: As Shown Material: Plastic+Metal Package Contents: 1 x Industrial Thermometer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
