Mahr Inc., a provider of dimensional metrology solutions, launched its updated Micromar 844 EWR(i) and Micromar 44 EWR(i) digital 3-point inside micrometers, offering advanced performance and a uniquely compact measuring element for precise inner diameter measurement. These latest models are engineered for greater ergonomic ease, enhanced precision, and increased connectivity.
Micromar 844 EWR(i)
Designed for rapid, repeatable measurements, the Micromar 844 EWR(i) features an ergonomic handle with lever retraction for quick measurements in one motion. Its lever stroke covers the entire application range of the self-centering measuring head, enabling seamless measurement of different diameters.
Additional highlights include:
- Available measuring range of 6mm to100mm
- Rotating display with touch operation for easy reading and adjustment, with an extra-hardened glass front
- Colored LEDs for measurement classification
- Spring-loaded measuring force ensures high reproducibility for through holes and blind holes
- Red operating keys for data command or hold function even when the display is not visible
Micromar 44 EWR(i)
The Micromar 44 EWR(i) introduces a more compact and lightweight plastic housing, offering improved sensitivity and user comfort. Ideal for precision work, it combines ease of handling with enhanced performance and rugged durability. The smooth ratchet stop enables controlled, ultra-precise measurements, and the large, high-contrast display also contributes to additional safety when reading off the measuring results and symbols.
Key features include:
- Wide measuring range of 6mm to 200mm
- Large screen with integrated tolerance display for error-free reading. The tolerance and warning limits function provides a clear and direct overview of tolerances
- High-contrast display to quickly read the 10 mm digits at a glance for clear, secure reading of results
While the 844 and 44 each offer distinct advantages, both models also share a range of powerful features that make them ideal for shop-floor and inspection applications, including:
- Wear- and corrosion-resistant measuring heads
- Measuring heads from 6mm to 30mm are chrome-plated for optimal protection in all workshop requirements
- Measuring heads 30mm and above feature lightweight black anodized aluminum bodies with noncorrosive stainless steel front panels for optimum durability and cleaning properties.
- USB and integrated wireless connectivity for easy data transfer and remote control via the free MarCom Professional software
- Three-value preset function for increased efficiency
“Mahr continues to create innovative metrology tools that combine accuracy, ergonomics, and digital connectivity to meet the demands of rigorous production environments,” said Dr. Farzad Azimi, Precision Gage Product Manager at Mahr Inc. “With the launch of the Micromar 844 EWR(i) and 44 EWR(i), we’re giving users the precision they expect for inner diameter measurement with greater ease of use and versatility.”
Both versions are available in wired (EWR) and wireless (EWRi) versions, individually or as part of a set to support a variety of measuring needs.
