Check the listing for details. Heathkit meter movement for 407-748 for Heathkit CO-2600 Auto analyzer. Condition: New. Listed at 45.00 USD. This is the meter movement that was used in the CO-2600 auto engine analyzer built by Heathkit. This meter is 8" across and the movement is a 1 milliamp 50 ohm meter. The last picture you see is what it looks like installed in the analyzer. If you need a replacement for your meter in your engine analyzer, now is the time to get it. I have 8 of them left. I got them from Heathkit when they closed up in Benton Harbor MI and there won't be any more when these are gone. They are new in the box. I'll pay the shipping and they'll go UPS with insurance. That applies to the 48 continental US. Alaska and Hawaii are extra (shipping rates are higher). If you're close to me (Grand Rapids MI area) you can pick this up and I'll reimburse the shipping cost.
