Indicating To obtain uniform conditions from modern equip ment, it is'necessary that the one in charge have a visual picture of actual conditions. If the individual units of the system are controlled automatically, the operator will know when this control is adequate and when it is not. Whether automatic or manual, the Brown Resistance Thermometer will detect all variations, allowing the operator to maintain the conditions as set forth in the specifications. Recording Uniformity of temperature and the consequent control of humidity depends on reliable facts obtained concerning wet- and dry-bulb temperatures. Controlling Brown Portable Thermometer Because the three-lead Brown Resistance Ther mometer is entirely independent of variations in lead resistance, variation in bulb location lengths, number of bulbs, etc., it affords an excellent means of obtaining reliable results. Bulbs may be placed at will or changed from one location to another; instruments may be moved about, and readings or records taken without any delay due to recali bration of leads, instruments or bulbs. In addition to Resistance Thermometers, the Brown Instrument Company manufactures: Thermometers Hygrometers Pressure and Vacuum Gauges Potentiometer Pyrometers Flow Meters CO2 Meters Tachometers Liquid Level Gauges See also Pages 1044-1049 930 Instruments Consolidated Ashcroft Hancock Co., Inc.
