Hamamatsu H7422 Series Photosensor Modules

  • High-Voltage Power Supply Circuit
  • Installed Cooler
  • Temperature Output Monitoring


The Hamamatsu H7422 Series Photosensor Modules feature an internal high-voltage power supply circuit and a cooler installed to the metal package photomultiplier tube. Efficient cooling was achieved by placing the cooler near the photomultiplier tube to reduce thermal noise emitted from the photocathode and a high S/N ratio can be obtained even at extremely low light levels. The photomultiplier tube is maintained at a constant temperature by monitoring the output from a thermistor installed near the photomultiplier and then regulating the current to the thermoelectric cooler.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
