The PRS - 812B Resistance Meter is a reliable and high - precision instrument. It can accurately measure resistance values in a wide range. With an easy - to - read display, it enables users to quickly obtain measurement results. Its stable performance ensures consistent accuracy, making it an ideal choice for electrical testing and maintenance tasks. 

The PRS-812B Resistance Meter is a fully portable, professional-grade instrument engineered for precision resistance measurement, delivering unparalleled accuracy and ease of use for ESD (Electrostatic Discharge) auditors and technicians. This advanced PRS-812B Resistance Meter provides a wide measurement range from 0.10 Ω to 1.00 x 10^12 Ω, with a remarkable accuracy of ±2% from 1.00 Ω to 9.99x10^10 Ω, ensuring reliable data for critical compliance verification. It is designed to meet and exceed international ESD measurement standards, including ANSI/ESD S20.20, ESD TR53, ANSI/ESD S4.1, and ANSI/ESD S7.1, making it the ideal tool for point-to-point (Rtt) and resistance-to-ground (Rtg) measurements on floors, worksurfaces, garments, packaging, and planar materials.

A standout feature of the PRS-812B Resistance Meter is its fully automatic operation. With three selectable modes—Automatic, Manual, and Auto-Manual—the device intelligently selects the optimal resistance range and test voltage (10V or 100V constant test voltages), simplifying the testing process and providing peace of mind. For extended field use, it is powered by a robust rechargeable Li-ion battery pack capable of approximately 8,000 measurements (typically 480 hours) on a single charge. The meter supports convenient charging via a standard Micro USB cable, either from a computer or the included global wall charger, reaching a full charge in just 2 hours. Additional user-centric features include a 120-data-set internal memory, a clear display showing readings in scientific or ohmic format, and an easy-access battery door. Complete with test leads, a test bed, clips, and a power supply, this portable, precision instrument is an indispensable asset for ensuring ESD program compliance in any facility.
