Description
The Hanna Instruments HI97727 is a high-precision, portable photometer engineered for the direct colorimetric determination of water color using the Platinum-Cobalt (PCU) scale. Utilizing an advanced optical system, this instrument integrates a specialized light-emitting diode (LED), a narrow-band interference filter, and a silicon photodetector to ensure highly repeatable and accurate measurements. The rugged IP67-rated waterproof housing makes it ideal for field analysis in municipal drinking water plants, industrial wastewater facilities, and environmental monitoring operations.
Original Engineering features include the CAL Check validation system, allowing users to verify instrument performance and calibrate against NIST-traceable standards at any time. The unit is designed for seamless Technical Compatibility with Hanna CAL Check standards and standard 25 mm cuvettes.

Application Scenario:
In municipal water treatment facilities, monitoring natural organic matter is critical to preventing the formation of harmful disinfection byproducts. The HI97727 allows field technicians to perform rapid, on-site colorimetric analysis of raw and treated water. By measuring true and apparent color down to 1 PCU, operators can instantly adjust coagulation and filtration processes to optimize chemical dosing, reducing operational costs and maintaining regulatory compliance.
Procurement and Logistics:
Standard Lead Time for this industrial-grade testing equipment is typically 3 to 5 business days, subject to regional distributor stock levels.
