The Cahn Gram Electrobalance,permit extremely long-duration runs at full precision without adjustment, and provision for taring to increase percentage precision, up to 2 ppm. The new instrument can be used in high vacuum, and with samples which are at high temperatures. It is not affected by vibration, normal shock, temperature, or temperature changes.frozen-shoulder 发表于 2025-3-27 07:53:00
Tungsten Helical-Spring Microbalance,about 550 ./mg and is so constructed as to avoid errors that might be caused by the thermal expansion of its parts or of the supports holding the balance and the cathetometer used in connection with it.辞职 发表于 2025-3-27 11:42:11
Introduction,sts actively engaged in research closely related to the relevant speciality. Constructive intercommunication with others seems simpler, faster, and happier than at larger meetings. The conference series on Vacuum Microbalance Techniques is a perfect example of gatherings of active scientists with a增减字母法 发表于 2025-3-27 14:14:14
The Cahn Gram Electrobalance, been developed using an elastic ribbon suspension, with capacity in excess of 1 g. Precision is 0.1 .g. The new instrument also has new circuitry to permit extremely long-duration runs at full precision without adjustment, and provision for taring to increase percentage precision, up to 2 ppm.
