Cahn C-31 Balance, Model C-31
Description: The Cahn 31 is a very sensitive weight and force measurement instrument. It is designed for weights and forces up to 3.5 grams and is sensitive to changes as small as 0.1 micrograms. The balance may be described as a force-to-cover converter. It consists of (1) a balance beam mounted to, supported by and pivoting about the center of a taut ribbon; (2) a torque motor coil located in a permanent magnetic field and also mounted to the taut ribbon; (3) sample suspension fixtures; (4) a beam position sensor system; and (5) controls, circuitry and indicators. Temperature: The Cahn 31 is designed for operation between 15 and 30 degrees C and a relative humidity between 5% and 95% (non-condensing). The balance requires 100, 120, 220, or 240 VAC (+/-10%) at 50 or 60 Hz., Performance Specifications: Sample Position: (A)or(B), Capacity: (A)1.5 grams, (B)3.5 grams, Weight Ranges/Sensitivity: (A) 25 mg/0.1ìg/250 mg/1ìg (B)1250 mg/10ìg, Tare: Mechanical, (A)1.5 grams, (B)3.5 grams, Electrical, (A)250 mg, (B)1250 mg, Accuracy: (percent of Weight range limited by precision), (A).0012%, (B).008%, Precision: Ultimate, (A)0.1ìg, (B)10ìg, Fraction of load, (A).0001%, (B).001%,
