Our right-handed torque wrenches offer an accuracy within 3% in accordance with ISO 6789:1-2017. Every torque wrench is manufactured and tested in line with DIN 3122 & ISO 6789:2017 standards. Our torque wrenches should be calibrated once every 12-months or every 5,000 clicks. Sending your Sonic torque wrench to a 3rd party vendor to be calibrated in accordance with the ISO 6789:2-2017 standards DOES NOT void your warranty. Each unit is also equipped with a unique product serial number for traceability and quality assurance.
