SPECIFICATIONS
MODEL 865 SPECIFICATIONS
TEMPERATURE SENSOR TYPE: Thermistor (2252 Ohm @ 77°F)
*ACCURACY: Includes repeatability, temperature coefficient (65° to 82°F), time sta-
bility (1 year), and linearization conformity errors. Excludes probe errors; however
probe errors around 32°F may be compensated by an internal adjustment.
REPEATABILITY: 0.2°F typical for 1 week at constant ambient temperature.
TEMPERATURE COEFFICIENT: 65° to 82°F; included in accuracy specification.
From 14° to 65° and 82° to 122°F; less than ±(0.06% rdg + 0.01°F)/°F.
SENSOR VOLTAGE: 40mV rms maximum.
MODEL 866 SPECIFICATIONS
TEMPERATURE SENSOR TYPE: Thermistor (2252 Ohm @ 25°C)
*ACCURACY: Includes repeatability, temperature coefficient (18° to 28°C), time sta-
bility (1 year), and linearization conformity errors. Excludes probe errors; however
probe errors around 0°C may be compensated by an internal adjustment.
REPEATABILITY: 0.1°C typical for 1 week at constant ambient temperature.
TEMPERATURE COEFFICIENT: 18° to 28°C; included in accuracy specification.
From –10° to 18° and 28° to 50°C; less than ±(0.06% rdg + 0.01°C)/°C.
SENSOR VOLTAGE: 40mV rms maximum.
