**Tracerco™ RADIATION Survey Meters**

# Tracerco T402 Dose Rate Survey Meters.

With a lightweight design and robust and reliable housing, the Tracerco T402 handheld radiation dose rate monitor measures x-ray and gamma-ray dose rate and peak dose exposure. The T402 responds quickly and has an extended range for measurements up to 100 mSv/h (10 rem/hr).

This versatile, rugged, and high-performance dose rate monitor is ideally suited for a range of applications such as oil and gas, mining, nuclear, medical, and environmental and life sciences. With peak dose rate memory for recording maximum exposure levels and easy-to-use controls with a backlight display, the T402 is the perfect companion when using your [880 Series](https://www.qsa-global.com/880-series-gamma-ray-source-projectors?hsLang=en) or [1075 SCARPro](https://www.qsa-global.com/sentinel-1075-scarpro?hsLang=en) gamma-ray source projectors.
