Di-Log DL7040 Digital Light Meter
The Di-Log DL7040 Digital Light Meter helps users check light levels across a wide range of sites. It measures up to 400,000 lux, so it suits general checks as well as high light areas. This makes it useful for environmental, health and safety, and industrial work.
Users can read results on a 4000 count digital LCD display. In addition, the bar graph display gives a quick view of changing light levels. The clear screen helps reduce errors during routine testing.
Wide Light Measurement
This meter covers two lux ranges for flexible use. The lower range measures 0 to 50,000 lux with higher accuracy. The upper range extends to 400,000 lux for brighter settings.
The Di-Log DL7040 Digital Light Meter also offers 0.1 lux maximum resolution. As a result, it can support closer checks where small light changes matter. Its 1.5 times per second measuring rate gives steady updates during testing.
Practical Field Functions
A long life silicon photo diode sensor supports reliable light detection. Meanwhile, peak hold, data hold, min and max hold, and relative reading help users record useful values. These functions make it easier to compare areas and track changes.
The Di-Log DL7040 Digital Light Meter is supplied with a rubber holster, attached diode sensor, cover, and carry case. It also includes auto power off, low battery indication, and over range indication. Therefore, it is well suited to regular site checks and portable use.
