The Standard Temperature Alarm is an auto- 
matic device to warn of abnormally high or 
low temperatures in Greenhouses. 
In places where heat is provided through auto- 
matically operated oil burners or stokers, and 
there is an ever present danger of loss of heat 
through mechanical or electrical power failure, 
installation of the Standard Temperature Alarm 
assures an automatic warning in case of fail- 
ure. Where hand fired heaters are installed, a 
Standard Alarm provides an automatic check- 
up on human forgetfulness or oversight. These 
Alarms will guard against low or high 
temperatures twenty-four hours a day. 
One cold snap or breakdown might cost you 
hundreds of dollars which could have been 
prevented, had you had sufficient WARNING. 
Watchdog of the greenhouse. Write for illus- 
trated circular.
