BAROGRAPHS – Recording barometers are rarely in need of maintenance, but occasionally they need attention. If the chart drum is key-wound, as older models are, the clock mechanism inside the drum needs periodic cleaning by a professional. We can handle that for you, and it takes only a few weeks. If your barograph has a battery-powered movement to turn the chart drum and it no longer works, in many cases we can replace it.
If the pen arm does not seem to respond properly to pressure changes, we can find out why and fix the problem. If you need a new supply of recorder charts, a new pen or new recorder ink, we’ll refer you to a new source since we no longer sell these items. Try us at 508-359-7467.
