Buy 4 R9420-20 Photomultiplier Tubes KITS and get 1 FREE Hamamatsu R9420-20 KIT - This listing is for an original Hamamatsu R9420-20 Photomultiplier Tube with the original Hamamatsu circuit board and electronics still intact. I provide the PMT, Data Sheet, and instructions to modify if desired, PLUS I provide a kit that includes all the electronics to do the modification. Once modified, this PMT works well with many battery operated survey meters and USB or battery powered High Voltage Bias Power Supplies, including Ludlum meters, Gamma Spectacular HV Bias Drivers, and Theremino PMT adapter. Ships with the Hamamatsu Data Sheet, Fully Illustrated Instructions and parts including the resistors, capacitor and wire leads, to modify the voltage divider. If you want to buy a R9420 that has already been modified, or save some money on just the bare tube, please see my other listings. These are PMTs that normally sells for hundreds of dollars when purchased new. These PMTs are great for Scintillation Counting and for Gamma Spectrometry. Each tube leaves my lab tested and guaranteed to satisfy. The R9420 is a 1.5 inch (38mm) diameter, Head-on type, Bialkali photocathode. The maximum spectral response is 300 to 650 nm, peaking near 420nm, great for use with NaI, plastic, or many other scintillators. This listing is for a Hamamatsu R9420-20 PMT only. Please check my listings for other configurations of this PMT and other available Photomultipliers and Scintillator supplies. Although I have more, this listing is for one PMT only. If you need more than the quantity eBay says is available, contact me for a special listing and price. Don't forget, buy 4 of these nice PMTs, and get a free one (5 for the price of 4). I ship very fast, same day if early enough, next day otherwise (except Holidays and Weekends). This item will be packed safe and secure. Only shipped to a PayPal Confirmed Address. Thanks for looking. Please don't forget to check my feedback and see my other items.
