HI97701

Photometer

Measurement range 0.00-5 mg/L, resolution 0.01mg/L, accuracy @25 ℃ reading +/- 3% +/- 0.03mg/L, LED high-quality Light source system, high-quality Optical inspection filter to ensure that the sample measurement results are consistent with the user.

Introduction

HI97701 complies with IP67 waterproof standards and uses an innovative optical system design with good accuracy, repeatability and time required to make measurements. HANNA's CAL CheckTM function allows performance verification and calibration of the instrument using NIST traceable standards. A variety of Measurement method, built-in reaction timer ensures consistent results between sample measurements and users, Good Laboratory Practice (GLP) display of date and time of last user calibration, battery status indicator light and automatic power-off setting.

Characteristics 

1. LED high-quality light source system. 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 of the higher heat. Will affect the stability of electronic products.

2. High quality optical filter, 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, more High measurement stability and less wavelength error ensure measurement precision and accuracy.

3. Reference Detector, an internal reference system that compensates for any drift due to battery Voltage fluctuations or ambient temperature changes, by automatically adjusting the Voltage of the LED to achieve a consistent and stable light source output, resulting in accurate readings between blank (zero) measurements and sample measurements. Fast and stable.

4. Stable and efficient light source settings and high-quality concave focusing lenses can collect all the light transmitted through the glass cuvette, reducing possible defects and scratch errors in the glass cuvette, and reducing defects in the glass cuvette. Errors and reading offsets caused.

5. 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.
