Hanna Chromium (VI) LR Portable Photometer with CAL Check- Meter Only – HI97749

Hanna HI97749 Chromium (VI) LR Portable Photometer is a high-precision analytical instrument designed for rapid and reliable determination of low-level hexavalent chromium (Cr⁶⁺) in water samples. Engineered for laboratory, industrial, and environmental applications, this photometer is ideal for on-site testing and routine monitoring where accurate detection of toxic chromium levels is critical for safety and regulatory compliance.

The instrument features an advanced optical system incorporating a reference detector, a narrow band interference filter, and a stable light source, ensuring exceptional accuracy, repeatability, and measurement stability. It operates using the diphenylcarbohydrazide method, adapted from the ASTM Manual of Water and Environmental Technology, providing trusted and compliant analytical performance.

With a measurement range of 0 to 300 µg/L and accuracy of ±10 µg/L ±4% at 25°C, the HI97749 delivers reliable results even at low chromium concentrations. The 8 nm narrow bandpass filter with ±1.0 nm wavelength accuracy enhances selectivity and minimizes interference, ensuring consistent and precise readings.

Designed for user convenience, the HI97749 includes a built-in tutorial mode that guides users step-by-step through measurement procedures, reducing errors and improving workflow efficiency. The CAL Check™ function allows instant verification of instrument performance, ensuring ongoing accuracy and confidence in results.

The photometer is equipped with a large 128 × 64 pixel backlit LCD display for clear visibility in all lighting conditions. Onboard memory supports storage of up to 50 readings with GLP-compliant logging, enabling traceability and quality control in professional environments.

Built for durability, the HI97749 features an IP67-rated enclosure, offering protection against dust, water, and high humidity. It operates reliably in challenging conditions ranging from 0 to 50°C and up to 100% relative humidity, making it suitable for both field and laboratory use.

Powered by three 1.5V AA alkaline batteries, the device supports over 800 measurements without backlight. The automatic shut-off feature conserves battery life during periods of inactivity, enhancing operational efficiency.

Supplied as a meter-only unit (reagents and accessories sold separately), the HI97749 uses standard 24.6 mm round cuvettes for accurate and consistent sample handling.

Widely used in industrial wastewater monitoring, environmental compliance testing, water treatment facilities, electroplating industries, manufacturing plants, and laboratory quality control, the HI97749 is essential for detecting hazardous chromium levels and ensuring environmental and regulatory safety.
