Numeric tubes

122P224 <p>The 122P224 Nixie tube (or B5092A) was made by Burroughs of the United States, so this is a genuine branded Nixie tube. This tube is special because it has Krypton 85 added, which is a radioactive isotope of Krypton that emits alpha particles. These keep the Neon ionized and so help reduce the time it takes the tube to 'ignite', especially in dark conditions.</p>
B54370A <p>The B54370A seems to be a variation of the B5441A - it has a comma in place of one of the decimal points, probably for use in displaying thousands.</p>
B6091 <p>The B6091 is a medium-sized Nixie tube made by Burroughs</p>
CD12 <p>Rodan-Okaya CD12 tube</p>
CD13 <p>The CD13 by Rodan-Okaya. A miniature top-view nixie tube.</p>
CD16B <p>The CD16B is a medium-sized nixie tube made by NEC of Japan</p>
CD18 <p>This CD18 was made in Japan by Matsushita. It is another tube that fits a B13B socket. The construction implies it was an early tube.</p>
CD24 <p>A CD24 tube made by Rodan-Okaya.</p>
CD25 <p>Rodan CD25</p>
CD27 <p>The CD27 is the largest top view nixie made by Rodan Okaya - at 54mm, the numerals are larger than the NL7037 and Z568.</p>
CD28 <p>The CD28 is a small nixie tube made by Rodan-Okaya of Japan.</p>
CD47 <p>The CD47 (GR-414) is the largest tube in the world, with a digit height of 135mm. It was made by Rodan-Okaya of Japan.</p>
CD66A <p>The CD66A is a medium sized nixie tube made by the Japanese company NEC</p>
CD72 <p>The Matsushita CD72 is a small Nixie tube with a digit height of 13mm. It includes a right-hand decimal point.</p>
CD80P <p>The CD80P is a small nixie tube made by Hitachi of Japan.</p>
CD-102 <p>The CD-102, made by NEC of Japan.</p>
CK8754 <p>The CK8754 is a numerical front-view nixie tube by the Raytheon company of America. It is a plug-in replacement for the NL840 and, like that tube, features a fine grid.</p>
G10/200E <p>The G10/200E is a nixie tube made by STC in England.</p>
GI-10 <p>National Union GI-10 Inditron. Widely accepted to be the first mass-produced 'nixie'.</p>
GI-21 <p>National Union GI-21 Inditron</p>
GN-1 <p>The GN-1 nixie tube made by STC of England, is a very early example of a nixie tube.</p>
GN-4P <p>This version of the GN-4 has a red-coating and a decimal point on the left and was manufactured by Lorenz SEL.</p>
GN5 <p>ITT GN5. A medium-sized top-view Nixie tube</p>
GN-13A <p>ITT GN-13A Nixie Tube</p>
GR-1 <p>The GR-1 is one of the first nixie tubes made by Rodan-Okaya (the other being the larger <a href="">GR-2</a>). You can see that the lettering on the tube is spelled <em>Rodin</em>, which is typical of the earlier tubes. This tube became the <a href="">GR-201</a> and eventually the CD11.</p>
GR-2 <p>Rodan-Okaya GR-2. Apparently an earlier version of the CD12.</p>
GR10G <p>The GR10G is a medium sized tube manufactured by ETL. It is unusual in that there is no solid back to the tube, so the digits can be viewed all the way around.</p>
GR10J <p>The GR10J numicator by HIVAC. A lot of HIVAC tubes have a distinctive gold-colored anode.</p>
GR10K <p>The GR10K is a medium-sized nixie tube made by the English company ETL.</p>
GR10W <p>This is the GR10W digitron - a medium-sized nixie tube by the English company ETL. Like its bigger brother the GR10G, this tube has a 360 degree anode mesh with no solid backing. Also like its brother, it has unusually high voltage and current requirements.</p>
