HLMS-200P Portable Integrating Sphere Photometer

Labsphere HLMS-200P Portable Sphere Photometer

Measure the flux of LEDs, small lamps & fibre optic illuminators

The Labsphere HLMS-200P is a convenient, hand-held photometer with 2-inch integrating sphere that is perfect for measuring the total luminous flux in lumens from individual LEDs, small lamps and fibre optic illuminators. The instrument’s photopically filtered silicon detector provides a wide dynamic range and the ability to measure from 0.05 to 7,000 lumens. The HLMS-200P is calibrated with reference to traceable NIST standards and a certificate of calibration is included.

The 2-inch Spectralon integrating sphere features a ½-inch input port which makes the HLMS-200P perfect for measuring small light sources. For larger samples, one of our bench-top photometers or spectroradiometers can be used.

The HLMS-200P is compact, lightweight, and rugged with a handle-grip enclosure. A built-in microprocessor provides numerous capabilities at the touch of a button, for example auto ranging, auto zero, ratio, display hold function and automatic switch off. Data is instantly displayed on a clear 4-digit LCD. Simple push button controls are easily accessible and clearly labeled on the front panel. The instrument is powered by a 9V battery and is calibrated to display lumens.

An optional adaptor set is available for reducing the standard 12.7mm (½-inch) size of the input port on the HLMS-200P. The set comprises the following adaptors: 2mm; 3mm (T1); 4mm; 5mm (T1-3/4), 8mm; and 10mm (T3 1/4, T3 3/4).
