Examples
-
Direct experiments with the Schönbein ozonometer and the psychrometer gave parallel curves; whence the author regards the former as only a crude hygrometer.
-
Compared with Schönbein's ozonometer, the results are in general directly opposite.
-
A table of results for the year 1879 is given in monthly means, of the two thallium papers, the ozonometer, the relative humidity, cloudiness, rain, and velocity of wind.
-
The objection to Schönbein's ozonometer (potassium iodide on starch paper) and to Houzeau's ozonometer (potassium iodide on red litmus paper) lies in the fact that their materials are hygroscopic, and their indications vary widely with the moisture of the air.
-
Schoenbein's ozonometer consists of 750 slips of dry bibulous paper prepared in the manner described; and with a scale of tints and instructions, sufficient to make observations on the ozone of the atmosphere twice a day for a year.

-
The air was tested every thirty minutes by an ozonometer, and the proportion of ozone found to be gradually diminishing; but as long as the paper of the instrument exhibited the slightest trace of blue, there was no smell, which only came on as the last signs of ozone disappeared.
