Hanna Aluminum CAL Check™ Standards - HI97712-11

Hanna HI97712-11 Aluminum CAL Check Standards Set is a precision calibration and validation solution designed to ensure the accuracy and reliability of the HI97712 Portable Aluminum Photometer. Ideal for laboratory, industrial, and environmental water analysis, this kit provides stable reference standards for verifying instrument performance in the 0.00–1.00 mg/L aluminum measurement range.

The set includes two sealed cuvettes: one “A” solution for zero calibration and one “B” standard solution that provides a certified value of 0.50 ±0.01 mg/L aluminum at 25°C. This allows users to perform both zeroing and validation checks, ensuring consistent and accurate photometric measurements.

Manufactured using high-purity, reagent-grade chemicals in a temperature-controlled environment, these standards deliver excellent stability and reproducibility. Each kit is supplied with a Certificate of Analysis, detailing product code, lot number, expiration date, certified reference values, and NIST traceability via a reference instrument. This ensures full compliance with Good Laboratory Practice (GLP) and quality assurance protocols.

The sealed cuvettes are housed in light-tight, rugged containers to prevent contamination and protect against breakage, preserving accuracy over extended use. Their ready-to-use format simplifies calibration procedures, reducing preparation time and minimizing the risk of user error.

Widely used in water treatment facilities, environmental laboratories, industrial process monitoring, and research institutions, the HI97712-11 standards provide a dependable solution for maintaining photometer accuracy and ensuring regulatory compliance.

Ensure consistent and traceable aluminum measurement with Hanna’s trusted calibration standards, designed for precision, stability, and long-term performance as part of Cal Check Standards
