pH, CHLORINE & PHOSPHATE DETERMINATIONS TAYLOR COMPARATORS Illustrated is the Taylor Model T-O, pH Comparator, basic set of the Taylor Line. All pH and many other slides may be used on the one base. In making a determination, the prepared sample is placed in the center tube in the base. The slide is moved across until the colors match. EASY TO READ . . . ASSURED ACCURACY The entire determination with a Taylor Comparator should take no more than 2 minutes even for an inexperienced operator. Since the complete set of color standards necessary for any one determination is enclosed in the durable molded plastic slide, the difficulties of handling and keeping track of fragile, single standards is eliminated. Continuing accuracy is assured by an unlimited guarantee against fading on all Taylor Liquid Color Standards. Taylor sets are light, durable and low in cost.
