Product Description

The HI97704 Hydrazine Portable Photometer is a precision laboratory instrument designed for convenient, rapid measurement of hydrazine concentrations in water samples, supporting ranges from 0 to 400 µg/L. Equipped with an advanced optical system that utilizes a reference detector and narrow band interference filters centered at 466 nm, this photometer ensures extremely fast and repeatable measurements with no required warm-up time.

Measures hydrazine in water within a 0–400 µg/L range (as N₂H₄).
Features tutorial mode for step-by-step operational guidance, making it user-friendly.
Automatic CAL Check verifies meter performance, ensuring reliable readings.
Support for GLP (Good Laboratory Practice) with a logging memory that stores up to 50 readings.
Operates on 3 × 1.5 V AA alkaline batteries, providing over 800 measurements per set without backlight.
Automatically shuts off after 15 minutes (30 minutes without readings) to conserve battery power.
Rugged construction with IP67 ingress protection; suitable for laboratory, water treatment, power plants, and industrial environments.
Measurement cuvette: round, 24.6 mm diameter (22 mm internal).
Hydrazine method: Adaptation of ASTM Manual of Water and Environmental Technology, Method D1385, using p-Dimethylaminobenzaldehyde.

This portable meter is crucial for applications requiring control of hydrazine, such as in boiler water treatment and high-pressure heating plants where it acts as an oxygen inhibitor to prevent scaling and corrosion. Its robust design and ease of use make it indispensable for regular monitoring in industrial and laboratory settings. The HI97704 is not supplied with reagents by default.
