Μετρητής Uni-T UT261B phase sequence meter

The Uni-T UT261B Phase Sequence and Motor Rotation Indicator is a handheld, battery-powered instrument designed to identify the phase sequence and rotation direction of three-phase systems. This device is widely used in electrical and industrial applications to ensure proper functioning and safety of motor-driven equipment.

Key Features:

• Voltage Measurement: The UT261B can measure AC voltage in the range of 90 to 600 volts, making it suitable for a variety of industrial settings. It also measures DC voltage up to 1000 volts, providing versatility in different applications.
• Frequency Range: This device operates within a frequency range of 15 to 400 Hz, covering the typical frequencies encountered in industrial environments.
• Phase Sequence Indication: The UT261B can determine the phase sequence of a three-phase system. It indicates whether the system is under positive or negative phase sequence by illuminating the "Clockwise" (R) or "Counter-clockwise" (L) rotation indicator, respectively.
• Motor Rotation Detection: The device can also detect the rotation direction of motors. By placing the UT261B in parallel with the motor shaft, it can indicate whether the motor is rotating in a clockwise or counter-clockwise direction.
• Durability: The UT261B is designed to be durable and can withstand impacts from a height of up to 2 meters, ensuring it can withstand the rigors of industrial environments.
• Safety and Compliance: The UT261B meets various safety and compliance standards, ensuring it is safe for use in industrial settings. It also includes a calibration/conformity report for added assurance.

This reliable and versatile tool offers precise measurements and clear indications of phase sequence and motor rotation. Its durability and ease of use make it an essential addition to any electrical testing toolkit.
