This Wm. B. Johnson Associates TVX-1A X-ray Emission Monitor is in used condition and appears to be functional. This item came from a local lab that had surplus equipment and shows some aesthetic signs of use. Unit was powered on with batteries (not included) and gauge reacted to dial selections. Monitor alarm went off for two of the dial selections but slowly faded over a short time. One minor issue worth noting is damage to the plastic cover as seen in first photo. We urge customers to view all photos as they show overall condition, included accessories, and functionality. Please feel free to contact us with any questions.
