Large-jaw Bluetooth smart temperature clamp for larger-diameter pipe that streams to the myNAVAC app and measureQuick.
The NAVAC NSTL is the large-clamp member of the NAVAC smart probe family, built with a wider jaw for larger-diameter pipe than the standard NST1 and NST2 clamps. Like the rest of the line it offers dual functionality with a built-in digital display and Bluetooth connectivity, a rechargeable lithium battery, and standalone operation, streaming temperature into the myNAVAC app and measureQuick for diagnostics.
