testo 830-T4

testo 830-T4 (testo-830-T4) is an infrared thermometer (pyrometer) with a 2-point laser target indicator, a socket for an additional probe, alarm signal, and 30:1 optics.

This high-class infrared thermometer (pyrometer) with 30:1 optics, a 2-point laser target indicator, and alarm function ensures reliable measurements at a distance. For example, the size of the measured point is 3.6 cm at a distance of 1 meter. The 2-point laser target indicator marks the diameter of the measured point, providing confidence that the temperature in unwanted measurement areas will not affect the results. This ensures measurement safety. To determine the emissivity coefficient, the surface temperature can be measured using a connected contact probe of type K thermocouple.

Main areas of application include:
— Control measurements in heating, ventilation, and air conditioning systems.
— Temperature monitoring in distribution rooms on ceilings, walls, and floors.
— Control measurements in electrical systems.
— Analyzing temperature changes in moving parts.

Key features include:
— Measurement point size of just 2.4 cm at a distance of 0.7 m, ideal for ensuring a safe distance from the measured object, such as hot parts or small surfaces like pipes.
— 2-point laser accurately shows the diameter of the measurement point.
— Connection of a contact probe to determine the emissivity coefficient.
— Adjustable emissivity coefficient (0.2…1.00)
— 2 measurements per second
— Audible alarm signal, customizable alarm values
— Display backlight
— Display of current and frozen values
