Portable Mercury Vapor Analyzer RA-915 Plus  Discontinued


Since its introduction nearly 20 years ago, the RA-915 Plus was widely accepted as the most accurate and sensitive mercury analyzer on the market.  Whether used as a standalone instrument for ambient air measurements or with attachments to analyze solids, liquids, and complex matrices, the RA-915 Plus has extensive capabilities.


NOTE: RA-915 Plus model has been discontinued and succeeded by the RA-915M model. Ohio Lumex will continue servicing RA-915 Plus units until further notice.

  • Since the RA-915 Plus has been discontinued, how long is it going to be serviced?"
    We will continue calibrating older units as long as they're functional. We will continue servicing older units until their replacement parts reserves are depleted.
  • How is RA-915 Plus different from the RA-915M model?
    The RA-915M is a further automated successor of the RA-915 Plus. The main advantage of the RA-915M is a new lightweight outer casing, built-in backlit screen display, automated calibration test cell and lamp ignition, a USB cable connection, and a higher upper detection limit (30,000 ng/m3 vs. 20,000 ng/m3).
  • Can older RA-915 Plus units be traded in for credit when purchasing a new analyzer?
    Yes. Please call us at 440-264-2500 for more details.
