Triplett Test Equipments & Tools
Triplett, a U.S.-based test equipment company, delivers innovative, reliable, and durable testers for every technician at an affordable price. Founded in 1904 in Bluffton, Ohio by Ray L. Triplett, the company began by producing the “Hot Wire” meter, an electrical test meter housed in a watch case. Continuing its tradition of innovation, Triplett introduced the model 310 hand-held analog volt/ohm meter, which remains in demand and is still manufactured today. Triplett produces testing equipment for major market categories, including Electrical Test & Measurement, Voice Data & Video Test, Security Camera Test, Vision and Inspection, Specialty Tools, and Toolkits. The company strives to be the go-to manufacturer for technicians everywhere.
Triplett offers a range of top-quality analog multimeter models renowned for their versatility, flexibility, and precise measurement capabilities of current, voltage, and resistance. These devices are essential for pinpointing faults in electrical circuits. Our analog VOM multimeters are compact, portable, and available in multiple configurations. These rugged instruments provide accurate readings across various electrical and electronic devices. Their precision indicators are engineered with tight tolerances, offering sensitive microampere suspension movements. Most models are designed to withstand temperature variations and other physical stresses, delivering performance comparable to larger bench-sized models.
Known as the “Trusty Workhorses” of the electronics testing industry, analog multimeters typically feature a pointer or needle to indicate voltage levels or outputs. They are user-friendly and provide measurements in ohms, amperes, and volts.

Triplett Corporation was founded in 1904 in Bluffton, Ohio by Ray L. Triplett. Triplett’s first innovative product was the “Hot Wire” meter, an electrical test meter housed in a watch case. Innovation continued
the READRITE Model 201 tube tester in the 1920’s, the 1200 series Radio Tuning Tester in the 1930’s, and meters for the U.S. Signal Corps during World War II. In 1955 Triplett launched the renowned Model 310 hand-held analog volt/ohm meter, which is still manufactured and highly sought-after today. Triplett continued to innovate, launching test equipment for mining, railroad, and telecommunications, including the Fox & Hound cable tracing kit. Acquired by Jewell Instruments in 2007, Triplett relocated to Jewell’s manufacturing facility in Manchester, New Hampshire.
Triplett continues to innovate, and we are known today for our full line of products in six major categories – Electrical Test & Measurement, Voice Data & Video Test, Security Camera Test, Vision and Inspection, Specialty Tools and Toolkits. In addition Triplett customizes test equipment for large end-customers in Security, DataComm, MRO, Mining, Rail and other markets.
Our goal is to carry on the legacy of innovation by staying connected to the customer experience. We aspire to be the brand of test equipment preferred by technicians.
