View our latest versions of this instrument, the T-10A and T-10MA

The easy to use T-10 and T-10M are handheld meters that measure the quality and brightness of specific locations highlighted by a light source.

(DISCONTINUED) T-10 and T-10M Illuminance Meters

The T-10 and T-10M Illuminance Meters are Lux meters. These devices are used to evaluate the lux measurement (illumination strength) of light hitting a particular location. These devices further provide the ability to calculate illumination and average values making them viewable on the LED screen.

The T-10 and T-10M Illuminance Meters display comparable illumination values as percentages or difference values according to user’s choice. The keypad allows users to enter targeted levels by measurement or manually. The T-10 series will automatically calibrate after powering up and features the ability to measure intermittent and continuous light sources. Users also have the option of entering color correction factors for the adaptation of particular light sources.

This lux meter has a vast measurement range (0.01 to 299,900lx) along with automatic range switching. This device has a removable receptor head to better accommodate a variety of measurements. Users have the capability of attaching up to 30 separate receptor heads for simultaneous multipoint measurements through a serial port that doesn’t require the lux meter itself to be moved; a convenient feature for large film screens that need the measurement of several areas at once.

The T-10M lux meter has a measurement area of 14mm diameter which is perfect for tight spaces and has the ability of measuring flickering light. This device is battery operated for portability.
