It all began in 1928, when Mr. Bollerman opened Pyrometer Instrument Company at 101-106 Lafayette Street, New York, NY.
The first products were contact and immersion thermocouple pyrometers for molten iron and steel foundries. Five years later, the company introduced a traditional non-contact optical pyrometer that incorporated a photoscreenic wedge. A photoscreenic wedge acts as a neutral density filter, which enables the measuring instrument to provide a clear, enlarged view of the target.
Steady market growth continued throughout the years of WWII, and shortly after the war, Mr. Bollerman moved the company headquarters to Bergenfield, NJ. At that time his son Paul, joined the company.
