This low-cost "production tool" makes it easier than ever to get quick, dependab le pho tomet r i c readings. In many industrial labo­ratories it is the basic equipment for quality control testing, inspec­tion . . . even research! In others it handles all routine work, taking the load off expensive, special-pur­pose equipment. • DEPENDABLE ACCURACY! Narrow band

pass (only 20 m/i! ) assures highest spectral purity.

• EASIEST TO USE! Dial inscantly sets Certiiied-Precision diffraction grating to desired wavelength; no color filters to fuss with.

• FASTEST READINGS! Instant-acting meter gives exact percent transmission, or optical density.

• LOW PRICE, DOUBLE VALUE! Colori­meter plus spectrophotometer 365m/i-950m/t range in one long-life, trouble-free instrument. (Extended range, 340m/£-950m/i at slight extra cost.)
