HK-I electromagnetic radiation detector

HK-I, a type of X-γ radiation alarm of personal dose equivalent (rate) – is the latest improved radiation protection for individuals. The instrument is mainly used for protection monitoring for X, γray and hard βray radiation, applicable in the field of nuclear power plants, accelerators, isotope applications, industrial X, γ nondestructive testing, radiology, cobalt source treatment, γ irradiation, radioactive laboratories, nuclear facilities ambient monitoring, etc.

Features of the Instrument:
* Fashionable appearance, comfortable handle feeling, skid proof edges.
*320 * 240 touchable color screen, true color display
* Built-in 128K Flash storage space can save up to 14,440 records (Automatically overwrite the old data when no enough space). Built-in query engine can check the saved data at any time and show the data via curve drawing.
* Powerful ARM instruction and floating point arithmetic ability of mathematics can quickly calculate the changes of surrounding nuclear radiation and take related reaction.
* With carabiner, USB cable, charger
*Simultaneous display cumulative dose, dose rate, alarm threshold, countdown, temperature, time and measurement cycle
* With unique LED lights, can reflects the strength of the ray basing on the flash frequency
* Preset dose rate and cumulative dose alarm threshold
* Arbitrary selection for the type of alarm among sound, vibration, light, silent
* Automatically switch the unit of measurement, always store the measurement data (or alarm data), save a cumulative dose and cumulative start date
* Low power design, battery voltage status indication, the cumulative dose and a variety of configuration parameters stored for long periods after power off
* Real-time clock function, the normal operation of the clock after shutdown
* Built-in fault detection, dose rate overload alarm and protection
