Wika 50025A005A4SF Bimetal Dial Thermometer 0-200F

Product Description

The WIKA 50025A005A4SF is a bimetal dial thermometer designed for temperature measurement in HVAC, plumbing, and industrial process applications. It reads from 0 to 200 degrees F and uses a back-connected mount, placing the stem inline with the dial face for direct pipe or fitting installation. The stem measures 2.5 inches in length, making it suited for insertion into standard process connections. The housing and stem are constructed from 18-8 stainless steel, providing corrosion resistance in wet or chemically active environments. Licensed HVAC technicians, plumbers, and facilities maintenance professionals install this type of instrument for continuous temperature monitoring at boilers, heat exchangers, chilled water lines, and similar systems.

This thermometer is appropriate for residential and light commercial HVAC systems, hydronic heating and cooling loops, domestic hot water systems, and general industrial piping where a visual temperature indication is required. The back-connected configuration is commonly used when the dial must face outward from a panel, fitting, or pipe wall for easy reading during routine service checks. The 0 to 200 degrees F range covers typical hot water heating and domestic water supply temperatures encountered in field service.

Key Features

• Temperature range of 0 to 200 degrees F (approximately -15 to 90 degrees C)
• 2.5 inch stem length for standard process connections
• Back-connected mount for flush panel or inline pipe installation
• 18-8 stainless steel construction for corrosion resistance
• 1.0 percent accuracy rating for reliable field readings

Compatibility

Designed as an OEM-style replacement or service upgrade for bimetal dial thermometer applications requiring a back-connected mount, a 2.5 inch stem, and a 0 to 200 degrees F measurement range.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Shut off flow and depressurize the line before removing or installing any thermometer well or direct-insertion fitting. Verify the connection fitting thread type and size match before insertion to avoid damage to the stem. Consult applicable local plumbing codes and ASHRAE guidelines for thermometer placement in hydronic systems.
