The Miljoco-Weiss A9VU35-240F is a Weiss Vari-Angle industrial glass thermometer with a 9″ scale, a 3-1/2″ stem for thermowell connection and a 30/240°F range in 2° divisions, accurate to ±1% of scale range.
The A7VU and A9VU series pair a V-shape die cast aluminum case with an adjustable joint that completely encloses the capillary to prevent tampering and keep foreign matter out of the instrument.
Temperature is read on a Blue Ribbon organic liquid fill in a magnifying glass lens tube, silicone shock mounted for lasting durability, against a white coated aluminum scale with permanently baked bold black markings.
Specifications on this page are taken from the Weiss A7VU & A9VU Series datasheet, revision A79VU-01.24. Verified 2026-09-11.
