Purpose and User

The TENMARS ELECTRONICS YF-172 is a digital lux meter designed for electricians and technicians who need to verify illumination levels on site. It measures intensity in Lux or Foot-candle units across four ranges up to 50,000 Lux and 5,000 Foot-candle. The sensor connects via a 1.5M wire for remote readings.

Sustained Measurement Behaviour

Accuracy is rated at +/-3% when calibrated to a standard incandescent lamp at 2856 K and corrected for LED daylight spectrum. Other visible light sources are measured within +/-6%. The 3 1/2 digit LCD displays a maximum reading of 1999 with overload and low battery indications. Light source selection covers Tungsten/Daylight, Fluorescent and eight rating settings.

Build and Daily Use

The meter body measures 200x98x40mm while the sensor housing is 125x98x40mm, weighing 325g including battery. Both units share a red finish and 98mm width for consistent handling. The package excludes batteries, so users must supply their own before first use. Compliance follows JISC1609:1993 general A class specifications.

Questions about this item

How much power does the YF-172 draw during continuous all-day use?

The meter runs on a standard 9 V battery (not supplied) and its low-battery indicator alerts you when the cell needs changing.

What must I supply before the YF-172 can take its first reading?

You need to insert a 9 V battery; the sensor cable and LCD display are already built into the unit.

Can the 1.5 m sensor cable on the YF-172 reach fixtures mounted on older high-bay fittings?

Yes, the 1.5 metre lead lets the sensor reach elevated or recessed luminaires while the display stays at working height.
