Weller WCU Digital Temperature Meter 0-400 °C with K-Type Sensor T0053450190

The Weller WCU stands out as a purpose-built digital temperature meter for soldering applications, offering a focused 0–400 °C range and K-type thermocouple input where generic multimeters fall short. Its 3.5-digit LCD delivers clear readings in °C or °F, updated 2.5 times per second for responsive monitoring.

Highlights

• Measures soldering tip temperatures from 0 to 400 °C (32 to 752 °F)
• K-type thermocouple input with included sensor for immediate use
• Manual offset calibration for precise adjustment
• Auto power off after approximately 3 minutes to conserve battery
• Powered by a 9V block battery with about 150 hours of life

In daily use

The WCU is tailored for quality control and tip temperature verification on soldering stations. Its compact, durable plastic housing suits bench or field use. The auto power-off function prevents battery drain during pauses, while the manual calibration lets you align readings with a reference standard for consistent results.
