• Hamar Laser Releases A-1700 Roll-Leveling Kit

    November 20, 2020

    High-accuracy electronic level works with Hamar Laser’s L-742 & L-732 laser systems to streamline roll alignments

    Hamar Laser Instruments has released its new A-1700 Roll-Leveling Kit. The A-1700 is an accessory kit designed to be used with the company’s L-742 and L-732 Dual Scan® Roll Alignment Systems. It comes with an easy-to-use, high-accuracy electronic level that transmits data wirelessly to Hamar’s R-1357-2.4ZB PDA Display.

    “Our A-1700 Roll-Leveling Kit makes accurate roll alignment easier and faster,” said Rod Hamar, President of Hamar Laser Instruments. “The A-1700 gives users the ability to quickly level rolls with a high-accuracy electronic level while using our L-742 or L-732 laser alignment systems to perform the more difficult parts of the alignment.”

    “A key feature of our level,” said Hamar, “is that its data is transmitted via Bluetooth to our R-1357-2.4ZB PDA, so users can see both the vertical and horizontal axes of the roll at the same time. This greatly speeds up the alignment and simplifies the process.”

    This powerful electronic level offers many benefits over conventional leveling devices:

    • High accuracy — Up to 5x higher than standard levels, with a resolution of .0002 in/ft (0.02 mm/m or 0.001°).
    • Digital values — Provides digital values that don’t need to be interpreted, like reading the edge of a bubble.
    • “Eyes-off” operation — Users don’t need to be looking down on the level to get the data, which can be very difficult in tight spaces and high elevations.
    • Real-time data — Data are displayed in real time, so it’s easy to see when the rolls are aligned.
    • Wireless transmission — Wireless up to 30 feet means users don’t have to be near the level to get data, making adjustments easier.

    The A-1700 Roll-Leveling Kit includes a v-block type mounting base for rolls from 2 to 24+ inches (51-610+ mm) in diameter, and a safety strap to prevent the electronic level from falling off rolls during alignments. The A-1700 can be purchased as part of L-742 and L-732 Dual Scan® Roll Alignment System packages, or separately.

  • Our colorful new Timeline tells the Hamar Laser story!

    September 24, 2020

    We’ve been pioneers in laser alignment since our founding in 1967 by Martin Hamar, a brilliant and enterprising Cornell-educated engineer with 29 patents to his name today. So it’s no surprise that we’re credited with many industry “firsts,” including these, to name just a few.

    • 1976 – World’s first automatically sweeping precision laser plane (Model L-711)
    • 1981 – First invisible IR diode-based bore alignment laser (L-800)
    • 1990 – First visible diode-based, 4-axis shaft alignment laser (S-640)
    • 1992 – Triple-Scan® laser with 3 automatically sweeping laser planes (L-723)
    • 1996 – Laser alignment system with both scan plane and square plumb beam (L-720)
    • 2000 – First wireless shaft alignment system in the market (S-650)

    We’ve just posted a Timeline to our new website that tells the interesting story of Hamar Laser’s 53+ years of innovation and leadership in words and pictures. Check it out!

  • New Product Release: R-1357-2.4ZB Android PDA Display

    April 8, 2020

    Ultra-rugged, next-gen R-1357 PDA features Android OS & versatile Read16 software

    Hamar Laser Instruments has released its new R-1357-2.4ZB Wireless PDA Readout. “We’re excited to release this ultra-rugged Android PDA, our first Android product, with more being planned for the future,” said Rod Hamar, President of Hamar Laser Instruments. “With IP68 and MIL-STD-810G environmental ratings and a new rugged design, our R-1357 is our next-gen wireless target data display that will serve our customers for many years to come. It features our new Read16 Android software with updated screens, more familiar operating functions and easier program flows.”

    The new R-1357 seamlessly integrates a next-gen Trimble Android PDA with Hamar Laser’s new Read16 proprietary software and a Zigbee® 2.4 GHz RF module offering these features:

    • Displays readings for up to 5 single-axis and two 2-axis targets, and the feature-rich package offers mode selections for numerous alignment functions, a laser setup wizard, graphic displays of target readings for roll alignment, a data-taking module, adjustable data averaging, and a data screen that summarizes the target readings.
    • Zigbee® uses a frequency-hopping protocol to avoid interference with other devices operating at the same frequency, so 2 or more systems can work in the same area and not interfere with each other.

    Available now, the R-1357 replaces the R-1356 and, like its predecessor, the new PDA works with Hamar’s A-1519 and A-1520 wireless targets and its entire line of lasers, including all L-740 / L-730 series auto-rotating lasers and L-702SP combination laser.
