HANNA HI97711 Portable waterproof residual chlorine/free chlorine/total chlorine photometer

Introduction

The HI97711 Residual Chlorine/Free Chlorine/Total Chlorine Photometer complies with IP67 waterproof standards and uses an innovative optical system design to provide excellent accuracy, repeatability and time required to make measurements. Hana's carefully designed CAL Check™ function allows NIST traceable standards perform performance verification and calibration of the instrument, multiple measurement methods, users can choose to use powder reagents or water reagents, built-in reaction timer to ensure consistent results between sample measurements and users, automatically record 50 measurement readings, Good Laboratory Practice (GLP) displays date and time of last user calibration, battery status indicator light and auto-off setting.

Features

• Compared with traditional tungsten lamps and other light sources, LED light sources have better performance and higher luminous efficiency. They can use less energy to provide stable light sources. LEDs can ignore the heat they generate because higher heat will affect the stability of electronic products. sex.

• 8 nm narrowband interference filter, accurate to ±1 nm, 25% higher absorbance, improved optical filter ensures higher Wavelength Accuracy and allows reception of brighter and stronger signals, higher measurement stability and Less wavelength error, ensuring measurement precision and accuracy.
  

• The internal reference system compensates for any drift caused by battery Voltage fluctuations or ambient temperature changes by automatically adjusting the Voltage of the LED to achieve a consistent and stable light source output, allowing readings to quickly stabilize between blank (zero) measurements and sample measurements.
  

• The high-quality concave focusing lens can collect all the light transmitted through the glass cuvette, reducing errors and readings caused by possible defects and scratches in the glass cuvette. offset.

• CAL Check™ feature, which allows performance verification and calibration of the instrument using NIST traceable standards; CAL Check™ NIST curve calibration set, which is used to simulate specific absorbance values ​​at each wavelength to verify the accuracy of subsequent readings. The CAL Check™ screen guides the user step-by-step through the verification process and user calibration.
