Johnson Level & Tool 40-6791 360-Degree Laser Detector with Clamp and Magnet

Description

Johnson Level & Tool 40-6791 360-Degree Laser Detector with Clamp and Magnet
Model #40-6791 Machine Mountable Detector
Accurately detects laser beam (635/650nm) signals from rotary lasers. This detector features:
-LED Display: Three LED's light up to alert on grade / too high / too low.
-Audible Alert: The detector will beep when a laser signal is found but is too high or too low. The LED's will indicate which direction to move the detector to find grade. A solid tone will indicate when the detector is on grade.
-Low Battery Indicator: The detector will perform a battery check at startup and alert you to a low battery or exhausted battery.
-The accuracy of this detector is not adjustable, and is:
= 0.06" for distances < 165'.
= 0.10" for distances > 165'.
Johnson Laser Detectors
When operating lasers outdoors on large jobsites, you typically can't see the beam. Laser detectors become a mandatory accessory to detect beam height and ensure the accuracy of your work.
Detectors must be chosen based on the color of the laser, the type of laser (line vs. rotary), and the style of detector required. Styles include single sided LED, single and dual style LCD, and machine mountable. All of the detectors shown here are for red beam rotary lasers (635/650nm).
Most Johnson Level detectors feature variable audible tones to tell you if you're too high, too low, or on grade. All detectors have a visual indicator to show you high/low/on grade, but the type of indicator varies by model.
