Wika 52090A004A4SF Bimetal Dial Thermometer 0-140F 9in

Product Description

The WIKA 52090A004A4SF is a bimetal dial thermometer designed for industrial and mechanical temperature measurement applications. It features an adjustable angle mount, allowing the dial face to be repositioned for clear readings in tight or angled installation points. The thermometer measures from 0 to 140 degrees F (negative 20 to 60 degrees C) with a 1.0 percent accuracy rating. The stem is constructed from 18-8 grade stainless steel and measures 9 inches in length. The stainless steel housing provides corrosion resistance suitable for demanding service environments. HVAC technicians, plumbers, and mechanical contractors install this type of instrument in pipelines, tanks, and process systems where direct immersion temperature monitoring is required.

This thermometer is suited for use in residential and light commercial HVAC systems, hydronic heating and cooling loops, plumbing systems, and general mechanical process lines where fluid or gas temperature must be monitored at the point of installation. The adjustable angle mount makes it practical in locations where a fixed-angle stem would leave the dial difficult to read. It is a single-unit package appropriate for individual installation or service replacement use.

Key Features

• Temperature range of 0 to 140 degrees F (negative 20 to 60 degrees C)
• 9-inch stainless steel immersion stem for deep pipe or tank installations
• Adjustable angle mount allows dial repositioning without moving the stem
• 1.0 percent accuracy rating suitable for HVAC and mechanical process use
• 18-8 grade stainless steel stem material resists corrosion in wet or chemically active environments
• Stainless steel housing for durable field performance

Compatibility

Designed as an OEM-style direct immersion bimetal thermometer replacement for hydronic, HVAC, and general mechanical process applications requiring a 9-inch stem with adjustable angle mounting.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Shut off and depressurize the system before inserting or removing the stem from any pressurized pipe or vessel. A thermowell is recommended for systems where the thermometer may need to be serviced without draining the line. Verify that the connection fitting matches the pipe or thermowell thread specification before installation.
