Otto Holzinger

Title: Otto Holzinger: Innovator in Photometry

Introduction

Otto Holzinger is a notable inventor based in Munich, Germany. He has made significant contributions to the field of photometry, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

Holzinger's latest patents include a photometer designed for measuring the light transparency of a substance. This device utilizes a light beam that illuminates the substance, allowing it to pass through and strike a photoelement, which generates a measuring current. The voltage produced from this current is logarithmated by a converter circuit and displayed on an indicating instrument. A zero balance control circuit ensures that the indicating instrument returns to a predetermined value based on previous measurements of a calibrated substance. If the transparency of the measured substance matches that of the calibrated one, the device indicates a zero value, while any deviation signifies a difference in transparency.

Another significant invention is the portable photometer, which is designed for hand-held operation outside of laboratory settings. This device is particularly useful for measuring the light permeability of materials, such as determining the proportion of hemoglobin in human blood. It features a battery power supply that energizes a lamp, an opening for receiving a cuvet for measurement, and a measuring circuit with a light-sensitive element. The indicator instrument within the measuring circuit shows zero compensation, and a manually movable wedge filter adjusts the light passing through the cuvet. A manually operable element allows for zero compensation before testing, and a viewable scale on the setting member directly displays the test result value.
