T-10A and T-10MA Illuminance Meters

2017-10-19      Click:40

     When you need to evaluate the illumination of light hitting a specific location or perform lux measurements, the T-10A is the illuminance meter of choice. This advanced lux meter will quickly show on the LCD screen the illumination and average values of measurements. You can easily compare illuminance values and have them shown either in a percentage or a difference value.

    Programming the T-10A is easy; you can enter target levels by taking actual measurements, or you can enter the levels by typing them on the handy keypad. The great versatility of this instrument allows for the measurement of both intermittent and continuous sources of light, and the unit calibrates automatically the instant it is turned on. Even first-time users find it simple to input color correction factors that can be used when measuring any specific light sources.

    The expansive measurement range of 0.01 up to 299,000 lx along with the ability to switch ranges automatically, make the T-10A one of the most useful and functional lux meters on the market today. For tasks that involve measuring pulse width modification of controlled sources of light, this instrument gives extremely accurate results. If you're measuring numerous sources, you can easily remove the instruments receptor head to simplify this process.

   As many as 30 receptor heads can be connected, which means users can perform measurements without having to make adjustments to the lux meter. This capability is particularly useful when a job involves big movie screens where simultaneous measurements of numerous areas is required. When you need to measure light in tight spaces, we've produced a convenient miniature receptor model. The T-10A now uses a USB cable to connect with a computer, rather than an RS-232C.
