Leeds & Northrup Resistance-Thermometer Bridge model 8063
LN resistance thermometer bridge model 8063 was used for moderate-precision temperature measurements by electrical resistance-thermometer method. It has a range from 0 to 200.1 Ohms. And error limit of /pm 0.005 ohm up to 10 ohms and /pm 0.05 per cent above 10 ohms. The Rheostat consists of 2 dial decades 9 ohm and a 100 ohm resistor which is removable by short circuiting link with an adjustable slidewire of 1.1 ohms.
It includes a battery key and comes in a polished mahogany case.
