Triplett Corporation was founded in 1904 in Bluffton, Ohio by Ray L. Triplett. Tripletts 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 1920s, the 1200 series Radio Tuning Tester in the 1930s, 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. Acquired by Jewell Instruments in 2007, Triplett relocated to Jewells 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.
