The Sciencetech PMH-01 Photon Counting Module is self-contained compact unit incorporating PMT tube, high-speed amplifier, discriminator, and high voltage power supply. The output signal (train of pulses, the number of which corresponds to the number of detected photons) can be sent via a BNC connector, to an external counting/displaying circuit. The PMH-01 outputs digital signal (pulses) only. There is no analog output port.

The photon counting head used has low power consumption (max 0.5W). It is already adjusted for best S/N ratio. There is no additional adjustment necessary to start the operation.

This product consists of the Sciencetech SOL-METER and our SSIVT-REF sun calibrated reference detector. The SOL-METER is a digital meter for use with select solar calibrated detectors. The meter converts detector measurements to a Sun value. This handheld meter is compact, has a sturdy design, and is appropriate for indoor or outdoor applications.

The Sciencetech Reference Detector, SSIVT-REF, which is an integral part of solar simulator calibration and solar cell I-V characterization, consists of a single element silicon detector and is designed to be used for monitoring and verifying the Sun level of solar simulators. The SSIVT-REF detector is used effective in sensing wavelengths between 190 nm and 1100 nm and is calibrated at Sciencetech against a NIST traceable calibrated reference cell. It does not have the capability for temperature measurement.

The SOL-METER is also compatible with detector model SOL-REF-Q. For temperature measurement in addition to irradiance measurements, please see the SOL-METER and SOL-REF-Q.

This product comes with a detachable cable with 4 banana plugs for connecting to a measurement device and is CE-compliant.
