This document is a service and parts letter from Hach Service dated July 30, 2025, addressing customers who have purchased instruments from their family of brands, including Hach, Great Lakes Instruments, American Sigma, Radiometer Analytical, Lachat, Marsh-McBirney, OptiQuant, Astro, Orbisphere, ELE, and Polymotron. The letter emphasizes the company's commitment to designing and manufacturing reliable, durable, and easy-to-operate instruments that provide accurate readings with minimal maintenance.

The document highlights Hach's service approach, noting that their Service Representatives are highly trained professionals with in-depth knowledge of instrument operations. As an ISO 9001 certified company, they maintain high-quality standards and do not authorize other service organizations to repair or calibrate their analyzers. The letter stresses that all parts used in their instruments meet specifications and that using non-Hach supplied parts will void the instrument's warranty. They offer service repair centers that can efficiently return instruments and provide an extensive field service organization. Customers are encouraged to contact Hach Service for additional information, with contact details provided at the bottom of the document.
