Frequently Asked Questions
-
Is this torque wrench truly non-sparking?
Yes, it is made from a copper-aluminum alloy that does not produce sparks when struck or rubbed against other metals. This makes it safe for use in explosive environments such as oil rigs and chemical plants. -
What materials are used in its construction?
The body is forged from high-strength copper-aluminum alloy, while the handle is covered with non-conductive rubber. All components are corrosion-resistant and designed for long service life. -
Can it be calibrated or adjusted?
Yes, the torque setting is adjustable using the knurled collar. For critical applications, we offer recalibration services; please contact us for details. -
What torque ranges are available?
We stock standard models from 20 Nm to 300 Nm. Custom ranges can be manufactured upon request with a minimum order quantity. -
Is it suitable for underwater or wet environments?
While the tool is corrosion-resistant, it is not specifically designed for prolonged submersion. However, it can be used in humid or damp conditions without immediate damage. Rinse and dry after exposure. -
How does it compare to standard steel torque wrenches?
Our non-sparking wrench is slightly heavier due to the copper alloy but provides equivalent torque accuracy. The major advantage is safety in hazardous locations where a spark could be catastrophic. -
What maintenance is required?
Keep the tool clean and lightly oil the moving parts periodically. Store in a dry place. The accuracy should be checked annually; we recommend returning it to us for verification. -
