Teledyne 1860-0125-0l Calibration Mechanism Drive Assembly

The Teledyne 1860-0125-01 Calibration Mechanism Drive Assembly is an internal mechanical drive that positions the calibration target within the optical head of Teledyne opacity monitors to enable automatic zero and span calibration. Installed in the optical head assembly and compatible with Teledyne LightHawk 560 opacity monitors (model dependent), it drives the automatic optical calibration mechanism during scheduled calibration cycles. This OEM replacement, repair, retrofit, and preventive maintenance component supports CEMS and stack opacity monitoring across power generation facilities, cement plants, steel mills, waste incineration plants, pulp and paper mills, chemical processing facilities, and other industrial emissions monitoring installations. Common replacements include 1860-0125-01, 1860-0125-03, and 1860-0175-01.
