    CellaTemp® PA 21 is a digital pyrometer featuring fibre optics to measure temperatures ranging from 300 to 2000 °C. The sensor head is housed separately from the electronics assembly. Both the sensor head and the fibre optic cable are unsusceptible to electromagnetic radiation. The optical sensor head can withstand ambient temperatures up to 250 °C without cooling. This variant is ideal for cramped, hard-to-access locations. 

    Công Ty TNHH và DV Tăng Minh Phát là nhà phân phối chính thức của hãng KELLER tại việt nam, chuyên cung cấp các thiết bị đo lường nhiệt độ hãng KELLER tại Việt Nam, KELLER Việt Nam
