Introducing the Model HI 9161F the world's first portable, printing thermo-hygrometer. This unique, lightweight meter gives instant print-outs of sample number, date and time of recording, printing interval, relative humidity and temperature at user-selectable intervals. The large LCD displays both Relative Humidity reading and temperature reading simultaneously. It has been designed to read from two separate probes, an R.H. probe and a temperature probe for increased flexibility. The HI 9161F comes complete with an HI 70604/2 R.H. probe with 2 meter (7') cable, and a HI 762L/2 general purpose temperature probe in a rugged carrying case.

Specifications Documented monitoring: Ideal for constant monitoring of R.H. levels. User Selectable Printing Intervals: Choose from 1,2,5,10,15,30,60,120 and 180 minute printing intervals.
