UNI-T Geiger Counter Radiation Dose Tester (UT334A)

The UT334A Radioactivity Geiger Counter is a compact detector used to monitor beta(β), gamma(γ) and X-rays. The device is highly sensitive and accurate. It is equipped with a high-performance microprocessor and TFT 2.0 color screen, which makes the operation convenient. The device is equipped with sound and visual signaling. Signaling threshold values can be set, when the threshold values are reached, the meter triggers an alarm. The main specifications correspond to international standards.
UT334A is suitable for use in radiation processing enterprises, health and epidemic prevention, radiotherapy, nuclear laboratory, nuclear power plant, building materials inspection, petrochemical, geological exploration, steel scrap production, industrial non-destructive testing and other environments where there is ionizing radiation, to monitor the radiation dose and to protect people.
