1.1 GENERAL
DESCRIPTION
The OMEGA
®
Models 865 and 866 are Hand Held Digital Thermometers with
large, easy to read, liquid crystal displays (LCD). The input connection for each
instrument consists of a
1
⁄
4
inch phone jack, which accommodates any one of
the available accessory thermistor based probes and sensors. The resistance
value of the thermistor at 25° C (77° F) is 2252 ohms. The instruments are pow-
ered by a 9 V battery. Continuous operation of 350 hours is typical with an
alkaline battery or 200 hours typical with a carbon-zinc battery.
The Model 865 measures temperatures on two ranges. The 300°F range
measures temperature from –70°F to 300°F with a resolution of 1°F. The
200° F range measures temperature from –70°F to 199.9°F with a
resolution of 0.1°F.
The Model 866 measures temperature from –55° to 150°C, on one range, with
a resolution of 0.1°C.
