2. Stop when full (Fill-then-stop)

*Not available with sample rates faster than 8 seconds.

Sample Rates: User-selectable rates from 25 per second to every 8 hours.

(BP-101 battery pack required for sample rates less than 8

seconds).

Resolution: 12-bit (1 part in 4096)

Power Consumption: 5 to 10 microamps (continuous)

Battery Life: Ten years (under normal use) factory replaceable.

External Connector: Removable screw-type terminal strip with Common (-)

connection.

Resistance to X-rays: Tested for protection against a 160kV 150mA-sec. dose @

38" FFD (about 100times that of an X-ray machine). Tested

for protection against Gamma Ray (equivalent to 0.137-1.38

megavolts) IR192-28 curies @ 30-second exposure source to

object distance 5".

Type: NTC thermistor; 10k ohms at 25°C (77°F)

Range: -40 to 70°C (-40 to 158°F)

Accuracy: ±0.2°C between 0 to 70°C (±0.3°F between 32 and 158°F)

Resolution: 0.03°C (0.05°F) at 25°C (77°F)

Better than 0.07°C (0.12°F) between -25 and 70°C (-13 and

158°F)
