$99.95 Shipping Condition: For parts or not working Location: Borger, United States Up for sale is a Vintage 1954 Nuclear Chicago Model 1613A Vacuum Tube Ratemeter/ Geiger Counter. With Probe, Tested and Working! It was brought up slowly ... moreon a Variac and. Woth the probe shield opened, exposed to a Thorium 232 Check Source. The speaker clicked to register detections, the light flashed and the meter responded, as the first picture shows. The GM tube in the included probe is marker"Lionel 112 6703-1" we have not been able to find specs for that tube. But are guessing either Beta/ Gamma or Alpha/ Beta/ Gamma, based on responsiveness to the check source. The external scope and meter outputs were not tested and are not guaranteed and. As with any vintage instrument, calibration is not guaranteed. It is is excellent vintage condition. With some scuffs, scratches, tape residue etc. As with any vintage vacuum tube equipment, you will want to replace capacitors, out of tolerance resistors etc if planning on extended use. This model rarely comes up and this is the only tested and working one on ebay- don't let it get away! Some history: The Nuclear Instrument and Chemical Company(NICC) started in 1946 making scaling circuits. They were located at 223-233 West Erie Street in Chicago. Illinois in 1949. The company was founded by John Kuranz, Thomas Mitchell and James Schoke at the Instrument Development Laboratories and the Metallurgical Laboratory(Met Lab) at the University of Chicago. In September 1948, the Instrument Development Laboratories(IDL) developer of the Model 2610, was incorporated into the Nuclear Instrument and Chemical Corporation. In 1954, they became Nuclear Chicago. They offered“Precision Instrumentation for Nuclear Measurements” The Model 1613 was introduced in 1950 as the“Classmaster” A training demonstration aid for classroom or laboratory instruction of radioactivity. It measured 9” x 10’ x 14” and weighed 16 lbs. It operated on AC power. It had an external thin wall glass Geiger tube for gamma and beta greater than 200 keV. It came with accessories including two radium
