New nylon-actuated knows the score
hygrometer
chart record showing alcohol level in blood sample. The main recording pen reveals the presence of alcohol. A Disc Integrator pen operating on the right side of the chart makes quantitative measurement of sample. A Disc Model 610 printer on top of the recorder produces a digital record of integration. Ask your Perkin-Elmer salesman for chromatograph details or for more information on the ElectroniK 194 and Disc Inte194

Psychrometric charts out! When you use the new Honeywell nylonactuated hygrometer that records directly in percent RH, there's no need for consultare
ing psychrometric charts.
It's available in
a
single-pen version for recording RH, or in a two-pen version for recording both temperature and RH. Packaged in a smartly designed case, the instrument weighs only 12 pounds and has a convenient hand-grip for easy portability. Circle reader service card No. 11.
Honeywell 194 Lab/Test
Recorder involved in blood alcohol test If alcohol is present in the blood of traffic
victims, the Honeywell ElectroniK 194 will tell the world. The Pennsylvania blood
alcohol program requires a blood sample of all traffic fatalities. This blood sample Is sent by the county coroner to the Pennsylvania Department of Health where it is analyzed by a PerkinElmer Model 900 Gas Chromatograph. The results are permanently recorded by a

Model 900 Gas Chromatograph. Circle reader service card No. 12. Hot recorder zeros in cold facts for freezer For a biological freezer to do its best job in preserving specimens, a recorder is
on
essential. The Honeywell ElectroniK 111 strip chart recorder is equipped to do everything required to accurately record data. It’s supplied with a chart and scale graduated —200 to+50°C for use with Linde BF-4 and other biological freezers. It provides monitorihg of the sample temperature throughout the freezing cycle. This aids the operator in determining rate selections during a cycle, based on thfe continuous record, The ElectroniK 111 also provides a permanent record of sample temperature vs. time, details of temperature changes while the sample is undergoing phase transition, and permanent data from which a file of sample characteristics can be compiled for duplication of phase transitions and freezing rates on future runs.
