Industrial Application:
This instrument is specifically designed for the condition monitoring of heavy-duty HVAC blowers, CNC spindle calibration, and conveyor belt velocity verification. In non-contact mode, the UT372D safely evaluates high-speed turbine shafts up to 99,999 RPM from a secure 500mm standoff distance. The contact mode utilizes interchangeable mechanical probes, including a Ø 0.1m surface wheel, to provide direct linear speed measurements for extrusion lines, paper mills, and web handling systems.
Procurement and Integration:
Engineered for broad Technical Compatibility with standard industrial maintenance toolkits, this tachometer supports immediate deployment across manufacturing facilities. Please consult our technical sales team for current Lead Time, calibration certificates, and volume procurement options.
