Due to the incredibly sensitive nature of AutoMeter’s high precision Pyrometers, it is critical for the accuracy of the instrument that the length of the probe harness never be modified. Unfortunately, some applications require a much longer run than a typical installation. Up until now, there hasn’t been a solution. AutoMeter’s Pyrometer Extension Modules provide an easy, affordable way to extend you harness up to 75’ additional feet with no loss in accuracy or response. Engineered specifically to work with AutoMeter gauges, you’re assured of easy, plug and play functionality and unmatched durability.
