Looking for a simple way to measure temperatures with your digital multimeter? Choose this thermocouple adapter and lead set from Keysight Technologies. It includes both type J and type K thermocouple beads for versatility. The set is compatible with handheld multimeters in the U1250A series for ease of assembly. Thanks to a wire temperature rating between -20°C and +200°C, you can collect results in demanding environments.

• Robust plastic housings with strain relief to protect contacts against damage
• Colour-coded J and K attachments for ease of identification
• Clearly marked poles for greater ease of use

• Industrial equipment testing
• Home appliances
• Construction industry
• Automotive applications
• Power stations

While a type J thermocouple is made of iron and constantan, a type K thermocouple is made of chrome and alumel for enhanced resistance to corrosion and acids.

A voltmeter only measures differences in voltage between two points in a circuit, while a multimeter can measure multiple properties, including frequency, capacitance and resistance.
