Product Name:Testo400Calibration level multifunctional measuring instrument

Product origin: Germany

Product Introduction:

Testo400Black bulb wet bulb temperature（WBGT）The index is used to evaluate the meteorological conditions in high-temperature workshops. It comprehensively considers four factors: air temperature, wind speed, air humidity, and radiant heatWBGTIt is composed of three temperature components: black sphere, natural wet sphere, and dry sphere.testo 400It is a powerful and high-performance reference level measuring instrument that can help you establish a quality assurance system, test the production process, and serve as a standard instrument for calibrating other instruments.

withVACmoduletesto 400The multifunctional measuring instrument is currently the only instrument in the world that can quickly and objectively evaluate the working conditions of air conditioning and ventilation systems without any manual calculations.
