Review on TruckMeter 015TM5003 Universal Thermocouple Pyrometer by Charlie Clayton

Works with my old Banks Dynafact pyrometer but gives you the option to use a 1/8" NPT connector instead of going to 1/4" NPT drill (which is also included, so it works with anyone). I bought 2 of these and added a switch to switch between cylinders 1-2-3 or 4-5-6 so I could keep track of any differences that might arise when filling up. Very satisfied. The included cables can be up to 2ft longer but should be fine for most applications (my sensor is on top of the dash).
