Product Description

The HI97710 portable photometer is designed for precise measurement of pH, free chlorine, and total chlorine in water samples. Featuring a reference detector and narrow band interference filters, it delivers exceptionally fast and repeatable results, making it an ideal instrument for water quality testing in diverse environments such as laboratories, water treatment plants, and field operations.

This meter covers a pH range from 6.5 to 8.5 with an accuracy of ±0.1 pH, and quantifies free and total chlorine from 0.00 to 5.00 mg/L (as Cl2) with superior precision (±0.03 mg/L ±3%). The photometer uses the EPA 330.5 DPD method for chlorine and Phenol Red method for pH analysis, ensuring compliance with standard laboratory practices. Its automatic calibration check (CAL Check) and tutorial mode simplify setup and usage, reducing the risk of operational error and improving result confidence. The meter is equipped with a large backlit LCD, automatic logging for 50 measurements, and supports both powder and liquid reagents for cost-effectiveness and operational flexibility.

Excellent accuracy and repeatability for pH, free chlorine, and total chlorine measurement.
Utilizes a high-quality silicon photocell with a narrow band interference filter at 525 nm.
Supports automatic shut-off, logging, and guided operation for efficient workflow.
Waterproof IP67 floating case allows for field use in harsh environments.
Battery operation supports over 800 measurements for portable applications.

Industrial, laboratory, environmental, and municipal users rely on this meter for water treatment, disinfection monitoring, and regulatory compliance. Supplied as meter only (reagents not included).
