Purpose and audience

The TeKit SM208 is a digital screen luminance meter designed for professionals who need to verify the brightness of fluorescent and transmission screens. It serves technicians working with TV sets, medical X-ray displays, CRTs and FED panels.

Build and connectivity

A compact yellow housing holds a mini light probe with a 10° measuring angle and a 20 mm object size at one metre distance. The probe connects directly to the main unit, requiring no extra cables or mounting hardware for bench or field use.

Thermals noise power

The silicon photocell detector delivers stable photometric readings with ±0.5 % precision across a 0.01–39990 cd/m² range. Low power consumption allows 100 hours of continuous operation from a single 9 V layer-built battery, and the instrument runs silently with no fan or active cooling.

Questions about this item

What measuring angle does the SM208's mini light probe use, and what luminance range does that cover?

The probe has a 10° measuring angle and covers a luminance range of 0.01 to 39990 cd/m² without requiring a dimmer.

What physical space is needed for the probe, and how does the target size change with distance?

The probe is compact and portable; at a 1 m measuring distance the minimum object size is 20 mm and increases as the distance grows.

How is the SM208 powered for installation, and what step do users often miss when starting a session?

It runs on a 9 V layer-built battery that provides up to 100 hours of continuous operation; users often forget to latch the peak value before recording data.
