Zinger developed a number of teaching methods widely used in geodetic practice. He proposed a method for determining the correction of clocks from observations of two stars at equal altitudes (Zinger’s method), participated in determining the difference in longitude between Warsaw and Pulkovo by telegraph, and investigated various types of personal errors in astronomical observations. 
Zinger is the author of courses on theoretical and practical astronomy, higher geodesy, and mathematical cartography.

He was awarded the Order of St. Anne 3 degrees (1872) and 1 degree (1902), St. Stanislav 2 degrees (1878) and 1 degree (1891), St. Vladimir 4 degrees (1880) and 3 degrees (1888; 25 years of service in teaching positions).
