Digital Multimeter InLine with Temperature Sensor 43117

The InLine Digital Multimeter with Temperature Sensor 43117 is a compact handheld instrument designed for a range of electrical measurements. It features a 3.5‑digit LCD display and measures DC and AC voltage, DC current, resistance, diodes, transistors, temperature and continuity. With a lightweight body (approx. 170 g) and dimensions of 138 x 68 x 31 mm, the device is suitable for portable use in workshops, service calls and home projects. The meter is powered by a 9 V battery and includes a built‑in temperature sensor for direct temperature readings.

Advantages

The multimeter combines multiple measurement functions in a single compact tool, offering clear numeric readout on a 3.5‑digit LCD and continuity/diode/transistor test modes for component verification. Its integrated temperature sensor expands functionality beyond electrical measurements, while the light weight and small footprint make it simple to carry and operate in confined spaces. Battery operation ensures mobility and quick replacement when needed.

Suitable for

• Electrical troubleshooting and circuit verification
• Measure DC and AC voltages in appliances and installations
• Checking DC current in small circuits
• Resistance measurements and component testing (diodes, transistors)
• Temperature measurement during equipment diagnostics
• Hobbyist and DIY electronics projects

Key specifications

• Display: 3.5‑digit LCD
• Power supply: 9 V battery
• Weight: approximately 170 g
• Dimensions: 138 x 68 x 31 mm
• Measurement functions: DC voltage, AC voltage, DC current, resistance, diode test, transistor test, continuity test, temperature
• Temperature measurement: built‑in temperature sensor (direct reading)

How to use

Select the appropriate measurement function using the meter’s range selector, connect the test leads to the correct input sockets and place the leads on the test points. For voltage and current measurements observe correct polarity and ensure the meter and leads are rated for the expected range. Use the diode and transistor modes to verify component functionality, and place the temperature sensor in contact with the object or ambient air for temperature readings. Replace the 9 V battery when the display indicates low battery to maintain accurate readings.

Recommendations

Always follow standard safety practices: disconnect power where possible before measuring resistance or continuity, avoid exceeding the meter’s measurement limits, and use appropriate personal protective equipment when working on live circuits. Store the meter in a dry environment and remove the battery for long‑term storage to prevent leakage.
