new simultaneous determinator (Check the linear dynamic range.) The linear dynamic range of our new electrometer is 107. And the total range is 10 10 (from 1 χ 10-14 A. to 1 χ 10-4 Α.). You'll find its junction field effect transistor circuitry highly reliable. It's com pletely solid state, has extremely low noise and is steady as a rock —drift less than 10-13 amperes a day. The input attenuator has five positions, five decades. The recorder output attenuator has 16 positions with a total range of 10 5 (100,000 times). Can your integrator handle the linear dynamic range of this electrometer? For complete information, write: The Bendix Corporation, Proc ess Instruments Division, Ronceverte, West Virginia 24970.
Bendix
...utilizes a single-use crucible in LECO'S exclusive Impulse Furnace to provide fast, accurate simultaneous nitrogen and oxygen determinations in metals and other materials. Operating t e m p e r a t u r e of approximately 2500° C is obtained in seconds for both cruci ble outgassing and analysis. The single-use crucible loads quickly and, after sample intro duction, all operations are automatic. Range is from less than 5 ppm to 1000 ppm for both nitrogen and oxygen. Weight compensator al lows results to be read directly from allelectronic digital displays. LECO'S Carbon and Sulfur Determinators...
...offer many of these same features... com pletely automatic, rapid analysis, wide range (0.001% to 50% for sulfur and 0.001% to 4.0% for carbon), direct reading and rugged con struction.
