NAC584.2371. Standards for recording thermometers.

     1. The chart for recording the temperature:

     (a) If circular, must make one revolution each 24-hour or 48-hour period; or

     (b) If a strip, must move not less than 1 inch per hour and may be continuous to a maximum of 1 month.

     2. The clock that governs the movement of the chart may be either manually wound or electrically operated. The time that is recorded must be the actual time.

     3. A circular chart for recording temperature must be a minimum of 10 inches in diameter if the minimum temperature is recorded at the maximum distance of the chart and 12 inches in diameter if the minimum temperature is recorded at the minimum distance of the chart. If a strip chart is used, the minimum temperature may be recorded at either the top or bottom of the chart but the width must be sufficient to enable the device to conform to the requirements of subsection 5.

     4. The case of the device for recording temperature must be moisture-proof when the device is operating.

     5. The device must be capable of recording temperatures from 30° to 160°F or above on a chart with lines for demarcating temperature of 1 degree or less between the range of 30° and 60°F. The device must be accurate to plus or minus 1 degree in the range of 30° to 60°F.

     6. The charts on which temperatures have been recorded must be kept at the dairy for 90 days and be available to the Commission during that time unless otherwise provided.
