TES Electrical Electronic Corp. 1334A Digital Lux Meter electrician tool

Digital Illuminometer with Data Hold

The TES 1334A is a handheld digital lux meter designed for measuring ambient light intensity in professional environments. It provides direct illuminance readings on a clear display for electricians, lighting installers and facility managers who need to verify compliance with workplace lighting standards or commission new installations.

Suited for spot checks and compliance work.

This meter suits technicians performing periodic spot checks, lighting audits or acceptance testing where a single held reading is sufficient. It is not intended for users who require automatic data logging, timed interval recording or computer connectivity for long-term trend analysis.

Data Hold function freezes the displayed value

The defining feature is the Data Hold button, which locks the current lux reading on the screen so the operator can move away from the measurement point to record the result safely. This single function determines whether the instrument matches a workflow that relies on manual note-taking rather than automated capture.
