Air Track Channel, B2-1950.12, £50.50
Air tracks without this channel can now be upgraded. This channel can be screwed to the air track so that it accepts photocell B2-1975.15. Note that air tracks previously supplied by Unilab may now be converted, using this channel, so that they accept our photocell. Before ordering, please check the suitability of your air track by contacting djb microtech.
