UNI-T UT18D: Professional Voltage and Continuity Tester
1. Advanced Voltage Tester for Electrical Professionals
The UNI-T UT18D is a sophisticated voltage and continuity tester specifically designed for the rigorous demands of professional electricians. It excels in precise AC/DC voltage measurement, comprehensive three-phase voltage analysis, accurate phase sequence detection, and reliable continuity testing. Classified under CAT IV 600V and adhering to IP65 standards, this robust instrument is the quintessential tool for rapid and accurate voltage assessments across diverse environments. TPT24, the globally recognized top online retailer, proudly offers the UT18D, ensuring product authenticity, unparalleled quality, and dependable worldwide delivery.
2. Engineered for Maximum Durability and Protection
Featuring an IP65-rated waterproof and dustproof design, the UT18D is constructed to endure the most challenging operational conditions. Its resilient build provides exceptional resistance against physical impacts, moisture, and dust ingress, making it an indispensable asset for electricians working in outdoor settings, industrial plants, and construction sites. This robust construction guarantees sustained high performance and reliability, ensuring longevity even in harsh working environments.
3. Comprehensive Testing Capabilities for Complex Systems
The UT18D is equipped with an extensive array of features, including RCD testing, precise polarity detection, and a comprehensive self-inspection function for its LCD. It also incorporates an “exceed voltage” warning and an efficient auto-standby mode to optimize battery life. These integrated functionalities render the UT18D an exceptionally versatile and indispensable tool, capable of executing a wide spectrum of electrical diagnostic tasks with paramount accuracy and efficiency.
4. Indispensable for Industrial and Commercial Diagnostics
This instrument is particularly well-suited for demanding industrial applications, such as factory automation systems, heavy machinery maintenance, and complex power distribution networks, where precise three-phase voltage and accurate phase sequence identification are absolutely critical. Its RCD test capability further enhances its value for ensuring the safety and compliance of electrical installations in commercial buildings and residential properties, thereby mitigating electrical hazards effectively.
5. Clear LCD Display for Precise Voltage Readouts
The UT18D features a large, backlit LCD that provides clear, precise digital readouts of voltage and frequency. This highly legible display, coupled with a practical work light, enables electricians to conduct safe and accurate assessments even in poorly illuminated areas. The digital display offers granular detail, significantly enhancing the precision of diagnostic work and ensuring reliable measurements in all lighting conditions.
6. Critical for Three-Phase System Assessment
A core strength of the UT18D is its capability to perform accurate phase rotation tests for three-phase systems. This function is paramount for ensuring the correct installation and optimal operation of three-phase motors and machinery, thereby preventing costly damage resulting from improper phase sequencing. The tester’s broad operating voltage range for phase rotation (57Vac to 400Vac) further broadens its applicability across various industrial contexts.
7. Advanced Features for Enhanced Safety and Utility
Beyond its fundamental measurement capabilities, the UT18D incorporates advanced features such as single-lead (L2) voltage detection for swift identification of live wires, and a silent mode for usage in environments sensitive to noise. A low battery indicator ensures continuous, reliable operation, while its CAT IV 600V safety rating underscores its superior protection against high transient voltages, prioritizing user safety above all other considerations.
