MICRO MAX

AUTOMATIC RECORDERSPractically any quantity which can be

reduced to electrical units of potential, cur-rent or resistance can be measured andrecorded by an automatically balancingMicromax potentiometer or bridge. Wheresmall temporary fluctuations are significant,where permanent records are necessary,where a continuous night and day record isdesired, where time cannot be spared formanual measurements, or where it is desiredto control automatically, the Micromaxmechanism is continually on the job . . .balances the circuit every two seconds andrecords continuously.

Developed primarily for industrial use,these recorders have a high degree of relia-bility and freedom from attention. Accurateand sensitive enough for a variety of routineresearch measurements, they make depend-able laboratory tools and are widely used ineducational, medical and industrial research.

Quantities measured include: temperature,pH, electrolytic conductivity, smoke density,frequency, C02, SO2, H2, 02, humidity, pres-sure, level, current, flow, kw, rkva, phaseangle, power factor, radiation, speed, etc.
