The infrared thermometer has been tested and conforms to the standard
ASTM E1965-98. ASTM laboratory accuracy requirements in the display range
of 96.8°F to102.2°F (36°C-39°C) for ear canal IR thermometers is ±0.4°F
(±0.2°C). Note that for mercury-in-glass and electronic thermometers, the
requirement per ASTM Standards E667-86 and E1112-86 is ±0.2°F (±0.1°C).
Security Class
Type of protection against electric shock: internally powered equipment.
Degree of protection against electric shock:
- Degree of protection against ingress of water:IP22
- Safety degree of using in flammable anesthetic gas blending with air, oxygen
or nitrous oxide: Non-AP/APG
- No applied parts of the thermometer prevents defibrillation charge effect.
- No applied parts of the thermometer output signal.
- The thermometer is impermanent installed device.
Storage and Transportation
The thermometer can be transported using general transportation tools.
Severe vibration, shock, or rain must be avoided during transportation.
The thermometer must be packaged and then stored in a well-ventilated room
without corrosive gas. The ambient temperature must be between –20°C
and +55°C -4°F–131°F , the relative humidity must be lower than 95% (non-
condensing), and the atmospheric pressure must be 50–106 kPa.
Type BF applied part.
