Keithley electrometers for every dc laboratory test m 'Φ $ Model 6ΙΟ, line-operated, 59 ranges The Keithley 610 Electrometer is a laboratory workhorse, doing the work of several instruments. It covers the ex- treme spans of dc voltage, current, and resistance tabu- lated below, and is a useful preamplifier as well. It has precise gains to 1000, a dc to 500 cps bandwidth, and 10-volt and 1-ma outputs. Input resistance of the 610 is selectable from one ohm to over 10 14 ohms. It checks its own resistance and voltage supply standards. Zero drift is comfortably within 2 millivolts per hour after warmup. Model 600, battery-operated, 53 ranges The Model 600 is a small, portable, battery-operated sister of the 610. Its many ranges also are tabulated below. Like the 610, its input resistance may be varied from one ohm to over 10 14 ohms, permitting an opti- mum balance of low circuit loading verus minimum pick- up. Output is sufficient to drive potentiometric recorders directly, with a dc to 100 cps band-width, and zero drift is within 2 millivolts per hour. The 600 will check its own batteries; minimum battery life is 500 hours. Need a few specials? Recent Keithley develop- ments include instruments for the Navy's Vanguard, for Army research balloons, and for Air Force research missiles. Your special prob- lem will receive a prompt reply.

Model 6 Ι Ο , line-operated, 59 ranges The Keithley 610 Electrometer is a laboratory workhorse, doing the work of several instruments. It covers the extreme spans of dc voltage, current, and resistance tabulated below, and is a useful preamplifier as well. It has precise gains to 1000, a dc to 500 cps bandwidth, and 10-volt and 1-ma outputs. Input resistance of the 610 is selectable from one ohm to over 1014 ohms. It checks its own resistance and voltage supply standards. Zero drift is comfortably within 2 millivolts per hour after warmup.
Model 6 0 0 , battery-operated, 53 ranges The Model 600 is a small, portable, battery-operated sister of the 610. Its many ranges also are tabulated below. Like the 610, its input resistance may be varied from one ohm to over 1014 ohms, permitting an optimum balance of low circuit loading verus minimum pickup. Output is sufficient to drive potentiometric recorders directly, with a dc to 100 cps band-width, and zero drift is within 2 millivolts per hour. The 600 will check its own batteries; minimum battery life is 500 hours.
