Topcon BM-7 and BM-5A

The Topcon BM-7, exclusively sold and serviced in North America by Hoffman Engineering, is a fully integrated photometer/colorimeter that automatically reads luminance and chromaticity coordinates and color temperature in a single measurement by simply focusing on the device to be measured and reading the LCD display. The BM-5A is a highly sensitive microprocessor-based photometer that quickly computes and displays chromaticity values, luminance and color temperature on a wide variety of displays and lighted devices. It is a simple, accurate operation which utilizes a photomultiplier tube detector for maximum sensitivity at low light levels. Both systems allow computer interface via RS-232 or GP-IB communications.  For technical specifications, click here: BM-7/BM-7-Fast or BM-5A.

BM-9 Spot Meter

The BM-9 Luminance Meter is Topcon’s newest instrument in a long line of instruments used to measure luminance. The BM-9 can also be utilized as a convenient remote in-line luminance meter. A built-in RS-232 makes it easy to connect to a P.C., enabling it to accurately measure all types of lighting.  For technical specifications, click here: BM-9
