Bausch and Lonb Automatic Dust Counter Mr. Nelson of American Smelting and Refining Co. gave a demonstration of the Bausch and Loab 40-2 Automatic Dust Counter. The Committee was impressed vdth its simplicity of operation and its versatility. It is portable and can be carried around with ease, and requires no special training to operate, i'aintenance is practically nil. By a simple adjustment the range of particle size to be counted can be changed. It also has the advantage that it gives instant and contin uous readings which, with the addition of a recorder, makes it possi ble to set the equipment up at a given station and monitor the atmos pheric conditions for extended periods of time. The present cost of the instrument is $3,800. plus $800. for the re corder. r It was suggested, for consideration, that the A.T.I. purchase one which could be rented or loaned to individual member companies. There was also some rfisc us sion on literature received from the Uaion Industrial Equipment Corp. which described the Unico Cassella Gravimetric ^Xist Sampler. This instrument still requires manual counting the same as the GreenbergShiith method. Environmental Health Survey j\ C j j j j A letter from Dr. Lewis J.
