Abstract
Abstract A hand-held radiometer for non-contact temperature measurement of objects is provided with a probe which is adapted to be mounted on the optical barrel of the radiometer to permit the radiometer to which it is attached to provide contact temperature measurements. The probe comprises a thin plastic film of low thermal mass which is shaped on one end thereof to be easily deformed when brought into contact with a specimen whose temperature is desired to be measured. The inner surface of the plastic film has a high emissivity, and a retainer means is provided on the other end of the thin plastic film for mounting the probe on the optical barrel of the radiometer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A radiometer probe adapted to be removedly attached to the optical barrel of a radiometer, comprising a. a probe having a thin plastic film of low thermal mass shaped to be easily deformed when brought into contact on one end thereof with a specimen whose temperature is desired to be measured whereby the thin film rapidly assumes the temperature of the specimen with which contact is made, b. the inner surface of said thin plastic film having a high emissivity, and c. retaining means on the other end of said thin plastic film for mounting said probe on the optical barrel of a radiometer whereby the radiometer views the inner surface of said thin plastic film from which an accurate temperature measurement of a specimen in contact with said probe can be made by the radiometer.
Claim 2
Dependent Claim
136 words
A radiometer probe adapted to be removedly attached to the optical barrel of a radiometer, comprising a. a probe having a thin plastic film of low thermal mass shaped to be easily deformed when brought into contact on one end thereof with a specimen whose temperature is desired to be measured whereby the thin film rapidly assumes the temperature of the specimen with which contact is made, b. the inner surface of said thin plastic film having a high emissivity, and c. retaining means on the other end of said thin plastic film for mounting said probe on the optical barrel of a radiometer whereby the radiometer views the inner surface of said thin plastic film from which an accurate temperature measurement of a specimen in contact with said probe can be made by the radiometer.
Claim 3
Dependent Claim
29 words
The radiometer probe set forth in claim 1 wherein said high emissivity of said inner surface of said radiometer probe comprises a high emissivity coating on said inner surface.
Claim 4
Dependent Claim
34 words
The radiometer probe set forth in claim 1 wherein said high emissivity of said inner surface of said radiometer probe comprises the material of said thin plastic film which has an inherent high emissivity.
Claim 5
Dependent Claim
31 words
The radiometer probe set forth in claim 1 wherein said retaining means comprises an annular clamping means adapted to frictionally engage the outer surface of an optical barrel of a radiometer.
