Description: This audible spirit level is designed to enable the user to check surfaces that are either horizontal or vertical. It can be as a conventional spirit level with the green and red LED lamps or with the audible tones. A high tone is produced if the left side is high, a low tone if the right side is high and no tone when the unit is level. The ruler can be pivoted to any angle and locked in place. When set to 90° it enables the device to check vertical surfaces. The bottom of the case has a V-shaped channel to locate it on curved edges such as pipes. Supplied with a protective pouch.
Powered by standard PP3 9v Alkaline battery (included).
