Detailed introduction
Inspector Alert™ V2 Handheld Surface Contamination Detector
The Inspector Alert™ V2 detector can be used to detect alpha, beta, gamma and X-rays. The built-in 2-inch flat GM detector is highly sensitive to alpha and beta ray sources. The digital display allows the selection of different units such as dose rate measurement μSv/hr or mR/hr and count rate measurement CPM or CPS as required. The detector can accurately detect minor pollution and can perform scheduled readings. The time can be set from 1 minute to 40 hours. When the radioactivity intensity reaches the alarm threshold set by the user, the instrument will send out an audible alarm signal.
Features:
l Quickly alarm when the environmental radioactivity intensity reaches harmful levels.
l Detects noble gases and low-energy radiation.
l automatic compensationGM manages dead time.
l Anti-saturation circuitry prevents interference in strong radiated fields.
l conform toCE certification, RoHS certification and WEEE standard.
Technical parameters:

l timer：Radiation reception time can be set1min to 40hr
l average period：everyIt updates once every 3 seconds and displays the average value of the previous 30 seconds. If the radiation intensity increases, the 30s averaging period will be shortened
l counting lights：every count redLED light flashes
l sound sound：There are corresponding sound prompts, which can be set to low noise
l Transport port Output: Can be transferred to computer, data logger, otherStereo 3.5mm jack for CMOS compatible devices, headsets and educational data collection systems. 0-9V, 1kΩ resistor
Input:A 2.5mm single jack provides calibration input. 0-3.3V, >5μs width, rising edge trigger
l Anti-saturation：The readout can display up to full scale in the field100 maximum readings
l ambient temperature：-20~50℃
l electricity source：One 9V alkaline battery can generally be used for 2000h. Under natural background, the battery can be used for 700h. The battery life decreases with the increase of radioactivity intensity.
