PAS pH Papers, Test Paper Sets, Measure-All

The Hydrion Measure-All pH Set is a comprehensive set for all colorimetric measurements of ph. The set provides for the pH measurement of most types of aqueous solutions and solid surfaces. It includes its own color standards and the means for vertifying these standards.

It is ideal for the illustration and demonstration of the properties of acids and bases, buffering and principles of colorimetric pH measurement. Hydrion Measure-All pH Set can be used for pH control and measurement work without any special technical training.

Measuring The pH Reaction Of Solid Surfaces
Hydrion pH Pencil measure surface pH reactions more conveniently and reliably than a glass electrode. Just mark a moist surface and compare the color with the color chart. The pH Pencil is a wide range pencil (pH 1-11) for general surface pH measurements.

Continuous pH Measurment By An Indicator Solution
The Hydrion Universal Indicator Solution is specially prepared to give color changes in test solutions from pH 1.0 to pH 11.0. It is supplied in a plastic dropper bottle and comes with a color chart that shows the actual color change for each pH unit. For precise color matches the indicator is used at the rate of one drop for each 4 ml. of solution. A 4 ml. capped tube is included for convenience.

pH Measurement Of Water And Unbuffered Solutions
The Hydrion Lo Ion Kit is designed to give correct pH readings in those special cases where indicator papers or isohydric indicator solutions may be in error by their influence on the pH of the solution being tested. These kits are especially valuable in ecological studies and in the measurement of the pH of raw waters and water supplies.
The kit consists of a dispenser of Lo Ion Test Paper for the pH range I to 11, a sample tube and cap, and a specially calibrated color comparator chart.

Rapid Measurement With pH Test Paper
Just dip and read--a color match tells you the pH in seconds! The Hydrion D-800 test paper dispenser covers the entire range from 0.0 to 14.0 with two superior test papers. One paper covers the range from 0 to 11 in steps of 1.0 pH unit. The second paper has color matches for every 0.5 pH unit from 12 to 14. The two test papers and their color charts are contained in one convenient, pocket sized, clear plastic dispenser.

Preperation Of Standard Buffer Solutions
Included in this set are four Chemvelopes - sealed foil packages containing pre-weighed amounts of quick dissolving buffer powders. When the contents are dissolved in 500 ml. (approx. 1 pint) of distilled water, the resultant solution will have the exact pH indicated on the label. The Measure-All pH Set contains 4 Chemvelopes, one each for pH 2.00, 4.00, 7.00 and 9.00.
Each component of the set comes in its own protective container and may be conveniently used as a separate unit.
