a new easy to use direct reading laboratory conductivity bridge
T h e YSI Model 31 Conductivity Bridge is brand new and spe cifically designed for laboratory use. Measure conductivity and resistivity w i t h c o n v e n i e n c e , speed, and accuracy at 60 cycles or 1 kc. Use it over the entire range of electrolytic conduct ance from demincralized water to strong acids. A u n i q u e m u l t i p l i e r scale, overlapping the basic scale, per mits fast, easy direct reading. A high intensity parallel bar elec tron ray tube provides easy, ex act determination of null. Line cord and electrodes are located out of the way. Specifically designed for the laboratory, the YSI Model 31 is the most easy to use conduc tivity bridge available. T h r e e new laboratory designed preci sion conductivity cells also are available. Ask us for full details.
