Operating
Instructions
This unique,
handy little gage
is great for use
in sensing the
temperature of
almost any
surface. The
bi-metal sensing
element is exposed
to allow quick accurate
response to surface
temperature, but adequately
shielded from damage by a protective cover and heat
collector. For the most accurate reading this surface
thermometer should be used in still air. Place the gage
on the surface where you wish to know the temperature
dial face up with bimetal sensing element against the
surface. The magnets will allow placement in any
position on a ferrous surface. It can also be used on any
other material with a horizontal surface. Allow about a
minute for the sensing element to stabilize and then
read the temperature. Higher or lower air temperatures
surrounding the thermometer or a draft over the surface
may slightly affect the temperature indicated.
Some Typical Applications
Air ducts, boilers, cabinets, drums, engines, enclosures,
fire boxes, manifolds, platens, plumbing, piping,
refrigerators and many others.
