Marshalltown-Tempco has been manufacturing precision instrumentation for temperature indication and control for
over 35 years.
Mountain Controls offers the Marshalltown-Tempco temperature instruments in the following table. Review the
information and accompanying datasheets and contact us to start your order.
T-2 and T-2E Series
The T-2 and T-2E series thermometers are ideal for outdoor applications and applications where vibration
causes issues with stability. These units feature weatherproof construction, a phenolic case, and a red
marking pointer that indicates the highest temperature reached between readings.
GM and GME Series
The GM and GME series are available in either direct mount or remote mount cases and provide temperature
measurement and/or control in applications that might encounter vibration. These units are available with
up to three snap-action switches to activate alarms or control equipment. A red marking pointer indicates
the highest temperature reached between readings.
The RC series is designed for applications that encounter vibration and that require both temperature
indication and control, such as oil-cooled electrical transformers. These units are available in a
weatherproof case with up to four micro switches to activate auxillary electrical equipment and alarm
devices, and the switch points can be adjusted without removing the unit from service.
The SCF series is a linear scale thermometer that features a liquid-actuating sensing system and
spiral-wound Bourdon tube to absorb shock and vibration, providing steady operation and accuracy in
The SJ series is a dial thermometer that can provide accurate temperature indication to applications that
encounter vibration. Like the SCF series, it employs a liquid-actuating temperature sensing system with a
spiral-wound Bourdon tube to absorb shock and provide steady, accurate operation. The SJ series is
available in a variety of case styles and temperature ranges.
Vapor Actuated Thermometers
Marshalltown-Tempco offers two basic styles of vapor-actuated thermometers to allow for either remote
mounting (up to 75 feet from the sensing bulb) or direct mounting of the thermometer for temperature
indication. They are available in a variety of case sizes, temperature ranges, and other choices such as
capillary and thermowell options.
Severe Service Vapor
Marshalltown-Tempco offers four models of severe service vapor thermometers for applications requiring
resistance to corrosion and severe vibration. They are available in a variety of sizes and temperature
