John......My Dakota Digital Gauge is ambient temp. adj. I want $75.00 plus shipping for it. I believe I may have 3 or 4, 10 ft thermocouple wires for it also. These are $26.00 each. These can be installed on all your cylinders and connected to a good rotary switch and then to the gauge so you can switch to any of the cylinders to read the temps. I'll sell the thermocouples for half price too. I may even have the rotary switch !
You can have all of this for half price and I'll throw in the switch. Dakota gauges are pretty accurate and I don't think the have a drop dead date on their life span. Let me know by Private email if you want them. Shipping via USPS Priority mail and insured will be about $16.00............Bruce
