TEMPERATURE ALARM ‘‘Standard”’ 
STANDARD 
The new STANDARD Temperature Alarm is a 
redesign of the unit used for over half a cen- 
tury as a temperature watchdog for the green- 
houses of America, and as a means to prevent 
plant and crop damage. 
Now fabricated in its entirety from non-ferrous 
materials, the handsome chromium-plated case, 
tugged indicating mechanism, and insulated 
wiring are not affected by moisture in the 
near-saturated air within the greenhouse. 
The six-inch, easy-to-read dial is finished with 
bright green numbers against a black back- 
ground—a combination permitting observation 
of the prevailing temperature at any time from 
a considerable distance. Scale 20°-100° F. 
The temperature-indicating hand and the con- 
trol hands, showing the maximum and mini- 
mum limits are finished in bright orange. These 
controls are easily adjusted by the setting 
knob, and this knob may then be locked, pre- 
venting unauthorized persons from tampering 
with, or changing the warning limits.
