TES Electrical Electronic Corp. 1311A thermometer thermocouple K memory electrician tool

Precision K-type thermometer for electricians

The TES 1311A is a handheld digital thermometer built for electrical professionals who need reliable temperature readings on the job. It accepts standard K-type thermocouple probes for contact measurements across a wide range. Onboard memory stores readings for later review, supporting documentation and compliance tasks. The red housing is designed for visibility in tool bags and busy work environments.

Integrates with standard probes and tool kits

The unit operates as a standalone meter, requiring only a compatible K-type probe to begin testing. It draws power from an internal battery, so no external supply or mains connection is needed during use. The compact form factor leaves bench space free and fits alongside multimeters, clamp meters and insulation testers in a standard electrician's pouch. Memory recall lets technicians verify logged data without a PC or software.

Replaces basic thermometers lacking logging

This model upgrades from simple display-only thermometers by adding data retention for audit trails and repeat visits. The jump is worthwhile when jobs require proof of temperature at specific points over time, such as motor bearing checks, panel inspections or HVAC verification. It is not suited for non-contact infrared scanning, high-voltage category rating beyond the probe limits, or multi-channel logging beyond the single input.
