AMMONIA concentration down to 0 . 0 0 5 ppm Chemical cryoscope is said to im prove determinations of molecular weight, chemical purity, solvent dilu tion, and other tests. Takes sample sizes down to 0.2 ml., and the probes have been tested to 0.0001° C. in the company's triple-point master stand ard. Advanced Instruments, Inc. P31 Survey M e t e r
Model 2586-T Cutie Pie surveymeter is used for rate of dose and cumulative dose radiation measure ments. The battery operated instru ment is supplied with two interchange able ionization chambers. A rate of dose chamber has ranges of 0 to 2.5, 0 to 25, and 0 to 250 roentgens per hour. An accumulated dose chamber has ranges of 0 to 0.25, 0 to 2.5, and 0 to 25 roentgens. The unit is designed for high level beta and gamma monitor ing or x-ray determinations, including direct beam measurement up to 10,000 roentgens per hour. Gamma and x-ray radiation are measured with energy in dependence. Betas above 50 kev. and alphas above 4.5 m.e.v. are also de tected. Nuclear-Chicago Corp. P-32
