Purpose-built illuminometer

The TENMARS TM-209N is a handheld lux and foot-candle meter designed for electricians and lighting technicians who need to verify illumination levels on site. It measures intensity using a silicon photodiode with a filter that matches the CIE luminous spectral efficiency curve. The cosine-corrected sensor ensures accurate readings across a wide angle of incidence. The instrument complies with JISC 1609:1993 and CNS 5119 general A class specifications.

Spectral correction limits

The meter applies nine factory correction factors so that readings reflect the true output of different light sources. Standard source A and LED white daylight are referenced at 1.00 and 0.990 respectively. Neon colours deviate more strongly: blue at 1.286, green at 1.167, pink at 0.760, purple at 0.804, red at 0.671, yellow at 0.840 and white at 0.870. Users working with unlisted spectra or requiring laboratory-grade uncertainty will need a spectroradiometer instead.

Field-ready construction

The red enclosure houses the sensor, display and controls in a single handheld unit powered by user-supplied batteries. A data-hold button freezes the reading for notation and the memory stores up to 99 manual records for later review. The package includes only the meter; batteries are not supplied. Buyers who need continuous logging, PC connectivity or a carrying case should look for a model that provides those features.

Questions about this item

Which measurement mode should I select for standard light source A?

Choose L0 or L9, both set to a 1.00 correction factor for standard light source A.

What does the 1.286 factor for NEON BLUE mean when the meter is in use?

The displayed lux or foot-candle value is multiplied by 1.286 to compensate for the meter's spectral response under blue neon light.

How does the JISC 1609 : 1993 and CNS 5119 class A rating affect real-world readings?

It confirms the meter meets those general class A specifications for illuminance accuracy and cosine correction.
