Get new technology for less. We may be able to replace the processor board in your old two-tube TimeMark counter with a new Gamma NT assembly. The case must be in good condition. If you have--
A Gamma in sheet metal case (approx. 6" x 5" x 4"): The battery brackets in some cases prevent them from being upgraded. Please check with us first to find out if yours can be used for an upgrade.
A Delta I, Delta II or Gamma in a cast aluminum case (approx. 11" x 8" x 5"): The new face plate will look slightly different than shown, but the processor board is the same. These upgrades must be done by TimeMark because the air switches must be modified.
NT Upgrades include new air switch gaskets and a lid gasket.
