HIOKI DT4910 K-Type Thermocouple | -40–260°C, tolerance ±2.5°C, φ0.5 mm, 80 cm long, for DT4253／DT4281／DT4282／CM4371-50 and others

Overview

In troubleshooting overheated motor bearings, temperature rise tests on switchboards and HVAC system inspections, accurate temperature data is the first line of defense against equipment trips and fires. The genuine authorized HIOKI (Japan) product DT4910 K-Type temperature probe (thermocouple lead) is a temperature sensing accessory designed for HIOKI digital multimeters and clamp meters with a temperature function (such as the DT4253, CM4371-50, CM4373-50).

The DT4910 is a K-type (Chromel-Alumel) exposed-junction thermocouple measuring -40–260°C with a tolerance of ±2.5°C; its red and black ends plug directly into the instrument's V／COM terminals.

Key Technical Specifications

Sensing Junction and Lead

• K-type thermocouple: Chromel-Alumel, exposed junction.
• Wire diameter φ0.5 mm, 80 cm long: The exposed junction is suited to contact measurement of surface temperature.

Broad Compatibility, Direct Connection

• Direct connection to the instrument: The red and black ends plug into the V／COM terminals; usable with the DT4253, DT4281 and DT4282 multimeters or the CM4371-50, CM4373-50, CM4375-50 and CM4141-50 clamp meters without an adapter (not compatible with the CM3286-50).
• Tolerance ±2.5°C: Exposed-junction K type, wire diameter φ0.5 mm, 80 cm long.

Applications

• Plant facilities and motor maintenance: Temperature rise tests on motor bearing housings, transformer overheating diagnosis, spot checks of contact temperature in high-voltage switchgear.
• HVAC and refrigeration: Inlet/outlet temperature difference on refrigerant lines; condenser and evaporator heat exchange efficiency assessment.
• Electronics R&D and quality verification (QA/QC): Temperature sampling of internal components in power supplies (SPS); heatsink performance verification.
