Up for sale is a vintage Victoreen Model 440-RF (also styled 440RF) portable radiation survey meter, manufactured by Victoreen Instrument Co., Cleveland, Ohio (later under Victoreen/Fluke/Cardinal Health lines). Serial No. 587. This is a specialized RF-shielded model designed for accurate measurement of low-energy X-rays and gamma radiation (e.g., in the presence of radiofrequency interference), commonly used in medical, industrial, TV receiver/cabinet X-ray compliance testing, and health physics applications.

Key Specs (from similar models/manuals):

• Ranges: 0-3, 0-10, 0-30, 0-100, 0-300 mR/h (milliroentgens per hour) – sensitive for low-intensity fields
• Ionization chamber detector (cylindrical tube visible in photos) with thin window for low-energy photons
• Battery-powered (uses standard batteries, compartment shown with springs/contacts)
• RF shielded to reduce interference up to certain levels
• Controls: Range selector knob with OFF/RESET, audio? (not visible), large analog meter

Condition:

• Vintage used condition with authentic industrial wear: Gray/black painted metal case shows scratches, scuffs, surface rust spots, paint chips, and minor dents (notable small dent/tear on top edge near handle as pictured). Handle is solid but shows age.
• Internals exposed/open (top cover removed/lifted in photos): Circuit board, wiring (multi-colored harness), components, ion chamber tube, and battery box visible. Appears complete with no obvious missing major parts, but some dust, old solder flux residue, and cosmetic corrosion on metal parts.
• Meter face clear, needle visible, knob turns, but untested – no power applied (no batteries included/tested), no radiation source used to check response. Sold strictly as-is for collection, display, historical interest, parts/repair, or restoration. May need cleaning, battery test, or calibration – common for vintage units like this.
• No accessories, manual, or probes included (manuals often available free online via search "Victoreen 440RF manual PDF").

This is a cool piece of mid-20th-century radiation detection history – the 440-RF series was built for specialized low-energy/RF environments (e.g., meeting FDA/HHS standards for X-ray systems). Great for vintage scientific instrument collectors, nuclear memorabilia fans, health physics gear enthusiasts, or as a cool display prop!

Important: Radiation detection vintage gear – untested/as-is/no returns. Not for critical safety use without proper testing/calibration. Please review all photos closely (they show exact condition, including internals). Message with questions before buying.

Shipping: Carefully packed (heavy metal unit) from Altoona, Pennsylvania via USPS Priority Mail (insured if value warrants). Combined shipping on multiple vintage items.

Thanks for looking – bid/buy with confidence in the description/photos!
