REINFORCING BAR STRESS METER
 GR-AN(for SD295), GRHN(for SD395),
 GR-ANT
(with temperature measuring), GR-HNT(with temperature measuring)
 
This meter is used to measure axial force or bending stress in reinforced concrete (beams, girders or diaphragm retaining walls). Installation of the meter may be by pressure welding of the meter to a reinforcing bar cut in advance before bar arrangement to a length matching the meter length (L=900 mm) or by attaching the meter to the reinforcing bar by binding wire, etc., without cutting the reinforcing bar. Select the installation method depending on the conditions of the job site.
