ACDelco 1/2" Heavy Duty Digital Torque Adapters 14.8 to 147.6 ft-lbs with Buzzer and LED Flash Notification – ISO 6789 Standards with Certificate of Calibration
- Transform your standard ratchet wrench into a highly accurate digital torque tool. It delivers professional-grade accuracy of ±2% clockwise and ±3% counter-clockwise from 20% to 100% of full scale. You can easily switch between four different measuring units to suit your specific needs: N-m, kg-cm, ft-lb, and in-lb.
- The adapter features two versatile measuring modes. Choose "Trace Mode" to view real-time torque readings as you apply force, or select "Peak Mode" which holds and displays the highest torque reading measured until you manually press the power button to clear it to zero.
- Equipped with an intelligent audio alert system to ensure precise tightening. An intermittent buzzer will start sounding to warn you when you reach 90% of your preset target torque value. Once the target torque value is reached, a high-frequency buzzer will sound to alert you not to pull further.
- The smart memory function automatically retains your last selected "mode" and "unit" settings, even after you replace the coin cell batteries. Additionally, it features a unique counter function that records the number of times the adapter has successfully reached the target torque (displays up to 999K times), allowing you to easily track the tool's usage history.
- Designed for durability and efficiency, the LCD display will show "999" and a high-frequency buzzer will sound if the applied torque exceeds 120% of the maximum torque, protecting the tool from damage. Powered by two CR2032 coin cells, the device includes an Auto Power Off feature that shuts down automatically after 60 seconds of no use to preserve battery life. It is available in 3/8” (ARM602-3) or 1/2” (ARM602-4, ARM602-4A) square drives.
