Robertshaw 10-038 Thermocouple Test Adapter

The Robertshaw 10-038 is a professional-grade thermocouple test adapter designed for HVAC technicians and maintenance professionals working with gas-fired heating systems. This essential diagnostic tool enables closed-circuit testing of thermocouples and thermopiles without disconnecting them from the gas valve, allowing for accurate millivolt and microamp readings while the system remains operational.

Key Features:

• One-piece brass body construction for enhanced durability and long service life
• Knurled grip design allows for hand-tight installation without wrenches
• Standard 1/4" NPT threading fits most gas valve applications
• Replaceable contact point for extended tool lifespan
• Quality terminals accommodate both DC millivolt and DC microamp meters
• Compatible with thermocouples and thermopiles for comprehensive system diagnostics

This adapter is particularly valuable for diagnosing thermocouple failures, testing pilot assemblies, and identifying defective pilot magnets. The hand-tight design speeds up testing procedures while the closed-circuit testing capability provides accurate readings that help technicians diagnose issues without unnecessary part replacement.
