High Precision Bench Top Torque Tester for Professional Tool Calibration
GEARWRENCH 1/2-Inch Drive Bench Top Torque Tester 25–250 ft/lb (33.9–339.0 Nm)
The GEARWRENCH 89634 Bench Top Torque Tester is a compact torque verification instrument designed for professional workshops and production environments where torque wrenches need to be checked for accuracy. With a 25–250 ft/lb (33.9–339.0 Nm) measurement range, it provides a practical way to inspect compatible 1/2-inch-drive torque wrenches at the point of use.
The tester features a backlit LCD display, three measurement modes, four selectable torque units, USB data connectivity, and dual-power operation through either AC power or its built-in rechargeable lithium-ion battery. It can also be securely mounted to a workbench or base plate using four screw bolts.
Key Features
25–250 ft/lb torque range accommodates a wide range of common 1/2-inch-drive torque wrenches.
Equivalent metric range of 33.9–339.0 Nm.
±1% clockwise accuracy from 20% to 100% of the tester's full range.
Designed for inspection and verification of torque wrenches in production and service environments.
Three measurement modes: Track, Peak, and First Peak.
Displays torque in ft/lb, in/lb, Nm, and kg/cm.
Backlit LCD display provides clear readings in low-light work areas.
Automatically calculates the percentage error between measured and set torque values, reducing the need for manual calculations.
USB interface allows test data to be uploaded for documentation and record keeping.
Operates from AC power or the built-in rechargeable lithium-ion battery.
10-minute automatic shutdown helps conserve battery power.
Can be mounted to a workbench or base plate using four screw bolts.
Compact steel construction is suitable for point-of-use torque verification.
Includes a rechargeable battery.
Designed for Torque Wrench Inspection
The 89634 is intended to help technicians and quality-control personnel verify the performance of torque wrenches, rather than measure the torque of an already-tightened fastener.
The tester accepts compatible 1/2-inch-drive torque wrenches and measures the torque applied during the test. This makes it useful for routine inspection programs where torque tools need to be checked before being returned to service.
Three Testing Modes
The tester provides three operating modes for different measurement requirements:
Track Mode – monitors torque as force is applied.
Peak Mode – captures the highest torque value reached.
First Peak Mode – detects the first significant peak during a torque application.
Having multiple modes allows the operator to select the measurement behavior that best matches the type of torque wrench being inspected.
Multiple Torque Measurement Units
The 89634 can display readings in four units:
ft/lb
in/lb
Nm
kg/cm
This makes the tester suitable for workshops where torque specifications may be provided in different measurement systems.
Accuracy and Error Calculation
GEARWRENCH specifies ±1% clockwise torque accuracy from 20% to 100% of the tester's full range. The unit can also calculate the percentage difference between the measured torque and the preset value, helping reduce manual calculation during inspection.
For quality-control applications, this can make routine torque-wrench verification more consistent and easier to document.
Backlit Display and USB Connectivity
The backlit LCD screen makes torque readings easier to see in darker workshop conditions. The built-in USB interface provides a way to upload test data, which can be useful for maintaining inspection records or documenting torque-tool performance.
The tester also includes an automatic 10-minute shutdown function to help preserve battery life when the unit is not being used.
AC or Rechargeable Battery Operation
The 89634 can be operated using a full-time AC connection or its built-in rechargeable lithium-ion battery. This gives technicians flexibility when the tester needs to be used at different points within a workshop.
The rechargeable battery is included with the unit.
Bench-Mountable Design
The tester is designed for stable point-of-use operation and can be fixed to a workbench or base plate with four screw bolts. Its compact footprint makes it suitable for dedicated torque-inspection stations without taking up excessive bench space.

Recommended Applications
The GEARWRENCH 89634 is well suited for:
Professional automotive repair shops
Fleet maintenance facilities
Industrial maintenance departments
Production workshops
Quality-control stations
Equipment service centers
Torque-tool inspection programs
Technician tool verification
It is particularly useful in environments where torque wrenches are used frequently and need periodic performance checks.
Important Use Note
The 89634 is a torque-wrench tester, not a tool for checking the torque already applied to a vehicle or machine fastener. It is designed to verify the output of compatible torque tools. GEARWRENCH specifically describes its bench testers as equipment for testing and verifying torque wrenches.
Compact Torque Verification for Professional Workspaces
The GEARWRENCH 89634 1/2-Inch Drive Bench Top Torque Tester provides a dedicated solution for checking torque wrenches across a 25–250 ft/lb range. Its combination of ±1% accuracy, multiple measurement units, three testing modes, backlit LCD, USB data transfer, dual-power operation, and bench-mounting capability makes it well suited to professional torque inspection environments.
For workshops and production facilities that depend on reliable torque-tool performance, the 89634 offers a compact and organized way to incorporate torque verification into routine maintenance and quality-control procedures.
