Mahr Inc., a provider of dimensional metrology solutions, newly updated its MarTest 800 EWR digital test indicators. The new versions of the 800 EWR incorporate an enhanced measuring system that provides longer measuring ranges of up to ±0.035"/±0.9 mm and ±0.086"/±2.2 mm, allowing for better accuracy and versatility. The MarTest 800 EWR combines the benefits of digital indicators, providing a longer measuring range with high resolution, enabling users to measure faster, more easily, and more reliably while minimizing errors. Combined with the ability to automatically sense measuring direction, rotate the bezel 360°, and overtravel protection features, the 800 EWR test indicator can replace numeral mechanical test indicators. The MarTest 800 EWR’s operating unit is also protected against coolants and lubricants, with a protection class of IP65. Its shockproof design and precision bearing supported lever contact offer maximum reliability in harsh environments. The full-surface glass display provides protection against liquids and dirt, which cannot penetrate the sealed housing. Key features of the MarTest 800 EWR digital indicator include: Inductive measuring system with a battery life of approximately two years Compliance with DIN/ISO standards (meets or exceeds) Four measuring modes: Min, Max, TIR, and Direct Combined analog and digital display 360° rotatable operating and display unit Automatic matching to sensing direction Satin chrome finished housing with three dovetail guideways Shockproof, anti-magnetic, and overload protection “Mahr’s family of digital indicators combine multiple features that can replace many dedicated and increasingly difficult-to-manufacture and maintain dial indicator products,” said Dr. Farzad Azimi, precision gage product manager at Mahr Inc. "The MarTest 800 EWR’s cutting-edge technology and user-friendly design make it the perfect solution for test indicating applications, providing unparalleled accuracy and efficiency."
