I'm reaching out to gather detailed quotes for various water analysis instruments. We are particularly interested in understanding the range of products you offer, including technical specifications, features, and pricing. It's essential that the instruments meet industry standards and are suitable for comprehensive water quality testing. Additionally, please include information on availability, lead times, and any bulk order discounts. If you have product brochures or datasheets, sharing those would be really helpful. We're looking to establish a reliable partnership, so details about warranty and after-sales support would also be appreciated. Looking forward to your prompt response!
