I am interested in acquiring and preserving old Heathkit weather and clock devices, along with manuals and other documentation.
If you have any of this equipment or know where to find it, please send me an e-mail.

The ID-2090 Barograph records barometric pressure on a paper chart.

The following announcement appeared in the December 1981 issue of Radio-Electronics magazine.

BAROGRAPH, model ID-2090, designed as a kit, provides digital readings of current barometric pressure and makes a permanent record of pressure changes. Barometric pressure - in inches of mercury (Hg), millibars, or kilopascals - is recorded on the drum chart. The chart can be adjusted to record at 7-day or 31-day speeds (with appropriate chart paper.) Written notations can be made by the user on the chart, during or after recording.

A four-digit LED display shows the current pressure (28-32 inches of mercury, 948-1083 millibars or 94.8-108.5 kilopascals) at the same time it's recorded on the chart. An LED indicates the unit of measurement currently in use (Hg, MB, or KPA). Cabinet switches allow the user to recall maximum and minimum barometric readings (since last cleared) with the time and date they occurred from the model ID-2090's memory. A separate 6-digit display alternately shows the current time (in 12- or 24-hour formats) and a 4-year calendar, or continuously displays time or date.

The easy-to-build kit features a transparent, smoked plastic dust cover for the chart-recorder drum. A one-year supply of chart paper is provided; additional chart paper and a replacement pen are available separately. The model ID-2090 is priced at $295.95, mail order. -- Heath Company, Benton Harbor, MI 49022
