Vector 5mm aperture, high resolution pyroelectric detector measures repetition rates up to 400 Hz and measure low energy levels (≤1.5 µJ). Ideal for measuring pulsed radiation. No power is required to drive the energy meters. These detectors may also connect to an oscilloscope. HR detectors contain a preamplifier powered by a 9 VDC battery that supplies noise-free power to the amplifying circuit. A low battery warning LED light located on the top of the detector prevents inaccurate readings.
