The Miljoco-Weiss V20662102-48 is a Miljoco V2066 remote reading vapor actuated dial thermometer with a 2″ stainless steel u-clamp case, a -40 to 65°F/C dual scale and a 48″ tin plated copper capillary to a nickel plated copper sensing bulb, accurate to ±one scale division.
These instruments are ideal for obtaining readings from remote locations. Being vapor actuated, they are not subject to ambient temperature variations along the tube system and give readings both above and below ambient.
Vapor instruments have progressive graduations and are best read in the upper two-thirds of the range. This model is designed for flush panel mounting and is furnished with a zinc plated CRS U-clamp.
Specifications on this page are taken from the Miljoco vapor actuated dial thermometer datasheet (2004_V20_Series_EN). Verified 2026-09-11.
Warranty
Miljoco-Weiss warrants its products to be free from material defects in material and workmanship for 12 months from the date of shipment, or such other period as provided in the product documentation, per the published Miljoco-Weiss terms and conditions of sale (Section 15, Limited Warranty).
Key Features
Remote reading
Ideal for obtaining readings from remote locations.
Vapor actuated thermal system
Not subject to ambient temperature variations along the tube system.
2″ u-clamp case
300 series stainless steel case with a rear outlet and polycarbonate, press-in lens.
Brass movement, phosphor bronze Bourdon tube
Brass movement with precision gearing drives a black adjustable pointer.
Dual °F and °C scale
Fahrenheit and Celsius graduations on a 2″ aluminum dial with white finish and black markings.
Over range protection standard
The datasheet states below-ambient ranges such as -40 to 65°F are furnished standard with over range protection, because they are over ranged during shipment and storage.

Source Notes
Source note: Sensing bulb diameter. The general specifications on the V20 model pages list a sensing bulb of 7/16″ diameter. The Sensing Bulb Dimensions table in the same datasheet lists a 0.250″ diameter, 2.0″ long bulb for the -40 to 65°F and -40 to 65°F/C ranges at all tube system lengths. This page publishes the range-specific table value. Confirm with the factory if bulb diameter is critical to the installation.
Source note: Capillary length. The general specifications list 60″ tin plated copper capillary as standard. This part number specifies a 48″ capillary through the ordering code, and the datasheet states that other capillary lengths are available. The ordered length is published here.

Frequently Asked Questions
What range and scale does the V20662102-48 have?
-40 to 65°F/C dual scale. °F scale figure interval 10°, division 2°; °C scale figure interval 10°, division 1°.
Where on the scale should the working temperature fall?
Vapor thermometers have progressive graduations and are best read in the upper two-thirds of the scale, so select a range that puts the working temperature in that area.
How long is the capillary and what is the bulb?
48″ of tin plated copper capillary to a nickel plated copper sensing bulb, 0.250″ in diameter and 2.0″ long per the datasheet bulb table.
Does the bulb height matter?
Yes. The datasheet cautions that the sensing bulb and case should be installed at a similar height to maintain the designed accuracy. Advise the factory when ordering if they must be mounted at different heights.
How is it mounted?
It is a 2″ U-clamp case with a rear outlet for flush panel mounting. The maximum panel thickness is 0.736″.
Is over range protection included?
Yes. The datasheet states that below-ambient ranges such as -40 to 65°F are furnished standard with over range protection.
