Pace Electrical Meters was a wholly-owned subsidiary of Precision Apparatus. PACO Electronics was the division for equipment in kit form.

Pacotronics was the parent company of all three companies. The name appears from around 1960 -  the exact ownership circumstances are currently unknown. Later tube testers like model 612 carry the "P" logo of Pacotronics, along with the statement "Precision - Test Instruments by Pacotronics", and the address of Precision Apparatus Co. on their documentation.

Founded: 1932
History:

In 1932, Solomon M. Weingast and Murray I. Menther formed a partnership (50-50%) under the firm name and style of Precision Apparatus Corporation. On March 27, 1946, the partnership was incorporated as Precision Apparatus Co. Inc.

In November 1951, Precision Apparatus was forbidden to use false, misleading and deceptive statements about their series 910, 912, 915, 620 and 922 instruments to be "Dynamic Mutual Conductance Type Tube Testers". This already started in 1940 as "Combination dynamic mutual conductance tube tester, 33 range rotary selective A, C.-D. C. Multi-Range set tester." (Order 48 F.T.C.). 

Precision moved from Elmhurst to a new plant in Glendale, Long Island by mid-summer of 1954. The new facilities consisted of about 21,300 square feet and about 14,000 square feet of additional open space. They also provided room for Pace, Precision's subsidiary for meters and other electrical instruments.

In a proceeding before the NY Supreme Court, December 27, 1956, Precision sucessfully petitioned against Precision Meter Co. for unfair competition - enjoining the latter from the continued use of the name Precision Meter Co.

From ca. 1959 on, PACO Electronics was the kit division of Precision for the sales of measurement instruments and Hi-Fi equipment in kit form.

In ca. 1967, Precision was sold to Dynascan, but continued to exist as a division.

This manufacturer was suggested by Georges Van Campenhout.
