UNI-T UT372 Non-Contact Digital Tachometer – 99,999 RPM Laser Photoelectric RPM Meter with USB Interface, Counter Function & Data Logging

The UNI-T UT372 is a professional-grade optical tachometer engineered for precise rotational speed measurements in automotive, industrial, and laboratory environments. By employing advanced photoelectric and laser technology, the UT372 allows technicians to safely diagnose motors, fans, pumps, and gears from a distance. Its non-contact nature makes it an essential tool for high-speed machinery where traditional contact-based tachometers would be dangerous or impractical to use. A standout feature of the UT372 is its integrated USB interface. Unlike basic handheld RPM meters, the UT372 can be connected to a PC to act as a continuous data logger, capturing performance trends over long durations. This is particularly valuable for research and development, quality control, and predictive maintenance programs where rotational stability must be documented over time. The high-contrast, 100,000-count LCD ensures that data is easily readable, while the inclusion of a revolution counter (up to 10kHz input) expands its utility beyond simple speed checking to full cycle monitoring. Built to withstand industrial rigors, the UT372 features a rugged housing that can survive a 1-meter drop and an ergonomic design for comfortable handheld use. It is powered by standard batteries and includes a "low power consumption" mode, allowing for up to 40 hours of continuous operation. Whether you are balancing an HVAC fan, calibrating a CNC spindle, or conducting automotive engine diagnostics, the UNI-T UT372 provides the high-frequency accuracy and modern data integration required for today's technical challenges.

Key Features:

Dual Measurement Modes: Features a versatile system that provides both RPM (Rotational Speed) and Count (Revolution Counter) modes, with a count range of 0 to 99,999.

USB Connectivity & Data Logging: Equipped with a built-in USB interface and PC software, allowing for real-time data synchronization, monitoring, and analysis on a computer.

Smart Data Processing: Includes professional modes for tracking MAX, MIN, and AVG (Average) values, as well as a Data Hold function to freeze readings on the 5-digit LCD.

Optimized Sensing Distance: Designed for a recommended measurement distance of 50mm to 200mm, providing reliable induction even in environments with minor interference.

Adjustable Sampling Rate: Users can customize the sampling rate from 0.5 to 255 seconds, making it adaptable for high-speed industrial machinery or slow-moving biological/mechanical rotations.
