Williams Comfort Products 501-I-ETT Electronic Torque Tester

Product Description

The WILLIAMS COMFORT PRODUCTS 501-I-ETT is a portable, battery-powered electronic torque tester built for trade professionals who need accurate torque verification in the field or at the bench. Designed around a 1/4 inch drive, it measures torque across a dual-scale range of 5 to 50 inch-pounds, making it suitable for fastener verification on HVAC equipment, electrical enclosures, plumbing fittings, and other assemblies where precise torque values are required. A power adapter cord (Part P115-30) is included, allowing the unit to run on AC power as an alternative to batteries. HVAC technicians, electricians, and plumbers use this tester to confirm that critical fasteners meet manufacturer torque specifications without relying on calibrated click wrenches alone.

This torque tester is suited for residential and light commercial service work where quick, portable torque verification is needed. It fits naturally into tool kits carried by licensed technicians servicing gas appliances, electrical panels, refrigeration equipment, and plumbing systems. The dual-scale display reduces the need to convert units on the job, supporting faster and more accurate documentation of torque readings during installation or inspection.

Key Features

• Dual-scale electronic readout covers 5 to 50 inch-pounds torque range
• 1/4 inch drive accepts standard sockets for broad fastener compatibility
• Portable, battery-powered operation for field and bench use
• Power adapter cord (Part P115-30) included for AC-powered operation
• Compact design supports use in confined service areas

Compatibility

Designed as a portable torque verification tool for use with standard 1/4 inch drive sockets across a variety of trade applications including HVAC, electrical, and plumbing service work.

Installation Notes

This tool requires no installation but should be handled and stored according to manufacturer guidelines to preserve calibration accuracy. Before use, verify battery charge or connect the included power adapter cord. Technicians should follow applicable codes and manufacturer torque specifications when using this tester to verify fastener torque on equipment under service. Do not use as a primary torque application tool — it is a verification and testing instrument only.
