Miniature 8-channel photon counter
id150 SERIES
-
Intended for large-volume OEM applications, the id150-1x8 is the only multichannel solid-state single photon detector on the market. It consists of a CMOS silicon chip packaged in a standard TO8-16pin header with a transparent window cap. The chip combines 8 in-line single photon avalanche diodes that can be accessed simultaneously for parallel processing. square in center-to-center A fast active quenching circuit is integrated within each pixel in order to operate each diode in photon counting regime. The chip is mounted on a printed circuit board on top of a single-stage thermoelectric cooler (TEC). A thermistor can be used to measure the temperature of the chip. Only two low power supplies of +5V and -25V are needed for operation in photon counting mode. The fast active quenching circuit leads to a dead time of less than 50ns per channel. An outstanding timing resolution of less than 60ps allows high accuracy measurements.

NI-9361, 32-Bit, 8-Channel C Series Counter Input Module
783407-02
Counter Input Module
32-Bit, 8-Channel C Series Counter Input Module - The NI‑9361 is a differential or single-ended input module. With this module, you can expand beyond the four counters in CompactDAQ to reach up to 64 counters per 8‑slot chassis. You can configure each channel to read a single pulse train or combine them to read up to four incremental encoders. You can also directly connect sensors with open-collector or push-pull outputs by using an internal switchable 1 kΩ pull‑up resistor. The NI‑9361 counters can perform encoder position and velocity measurements. You can synchronize the counters with other analog, digital, and counter measurements in your chassis.

Particle Counter
VLT-E9700
-
Modern diesel engines are quite clean, provided the soot filter is present and working properly. A soot filter can get clogged, or even malfunction. In that case the filter has to be cleaned or replaced. Unfortunately, sometimes the vehicle owner has the filter removed altogether. When the filter has been physically removed, it is ‘programmed out’ of the vehicle software, so that the removal of the filter remains undetected during an (E)OBD check. This is why in ever more countries a particle count is mandatory during a periodic inspection of e diesel vehicle.

Geiger Counter
ONYX®
-
ONYX features a modern, streamlined look and the use of advanced technologies, making it a one-of-a-kind Geiger Counter. It weighs only 7 oz. (200g.) and measures a mere 5.1 X 2.6 X 0.9 in. (72 X 37 X 13 mm.) making it easy to transport. Despite its compact size ONYX is capable of detecting alpha, beta and gamma radiation with the same sensitivity as the IMI Inspector Alert™, and like the IMI Inspector Alert™ V2, ONYX is optimized for surface contamination measurements through use of its 2 in. pancake Geiger Mueller tube.

Frequency Counters
-
Frequency counter models can be direct or reciprocal counters. Direct counting models count signal cycles for a specified period, called the gate time, and resolution is in Hertz. Reciprocal counters provide faster, higher resolution performance, with resolution listed is in digits/second. When shopping for a counter, remember to review resolution and accuracy as separate specifications. The resolution of a frequency counter is the smallest change it will detect between closely spaced frequencies.
