This edition reviews the Testboy TV 335 Digital LED/Lux Meter, a light meter brimming with features and capable of measuring multiple light sources, including LED light.

About Testboy

For more than 60 years, Testboy has been offering measuring and testing devices for various applications and purposes. Testboy equipment guarantees the highest possible level of user-friendliness alongside an ultra-long and reliable service life.

Introducing the Testboy TV 335 Digital LED Light Meter

The Testboy TV 335 is a digital light meter packed into a robust plastic housing with an extended measuring range of up to 400,000 lux. Thanks to the artificial light-sensitive photodiode and user-adjustable colour temperature, the Testboy TV 335 is suitable for determining the light intensity of many different light sources, including LED lighting. 

Impressive Features and Benefits of the Testboy TV 335 Digital LED Light MeterTestboy

• Versatile and practical: The extensive measurement range and built-in photodiodes sensitive to artificial light make the Testboy TV 335 suitable for measuring various natural and artificial light sources.

• Adjustable colour temperature: Easily choose differing sources of light between; standard sources of light, white daylight, red light, amber light, green light, blue light, and purple light.

• Handy data-hold function: This function freezes measurements on the display so you can record measurement results painlessly.

• Sensor protection cover: The included sensor cover keeps the sensor safe when not in use and is used to perform zero adjustments.

• Straightforward zero-adjustment: Users can perform a quick and easy zero adjustment on the meter at any time without any additional equipment. Place the cap over the sensor and press the HOLD/ZERO button to perform the adjustment.

• Automatic/manual range selection: Choose between one of the four measurement range modes or select AUTO, and the range will be automatically selected based on the incidence of light.

• Make easy light level comparisons with Relative Measurement Mode. Users can set a reference value based on the current lighting measurement, and the device will indicate the differential values to the reference value set.

• Peak measurement function: This function increases the sensor’s response time, with which quicker changes in light can be recorded, helping you evaluate the highest measured value with ease.

• Minimum and maximum values: Using the MAX/MIN function, the respective largest and smallest measurement values are saved and indicated.
