Microcomputer residual chlorine (free chlorine) photometerIntroduction:

Measurement range: 0.00 to 5.00 mg/L (ppm) CI2
Adopting innovative optical system design, with good accuracy, repeatability, and measurement time required, Hanna's carefully designed CAL Check ™ The function allows for performance validation and calibration of instruments using NIST traceable standards, with a built-in reaction timer to ensure results between sample measurements and users *, Good Laboratory Practice (GLP) display of the last user calibration date and time, battery status indicator light, and automatic shutdown settings
Reminder: The new HI97701 residual chlorine [free chlorine] analyzer adopts a menu operation mode, which allows you to choose between using powder or water residual chlorine DPD reagents, thereby increasing your options and reducing usage costs.

Chlorine is a commonly used water disinfectant with a wide range of applications, from the treatment of drinking water and wastewater to the sanitation treatment of swimming pools and mineral spring resorts, as well as disinfection and sterilization in food processing; Based on microprocessor control, it has self checking function and can quickly measure residual chlorine concentration accurately

The residual chlorine spectrophotometer is equipped with an advanced narrowband interference filter and silicon photodetector combination optical system, ensuring accurate measurement readings every time; Hanna's meticulously designed CAL Check ™ Function HI96701-11 residual chlorine NIST traceable calibration group to verify the performance status of HI96701 residual chlorine photometric colorimeter. The dedicated colorimetric cup locking design ensures that the colorimetric cup is inserted into the same position in the measuring unit each time to maintain the path length of * for accurate results,

Microcomputer residual chlorine (free chlorine) photometerparameter

It is simple and convenient to add reagents to the water sample to be tested. The reagents will react with chlorine in the water sample to form a light red color. Based on the color change after the reaction between the reagents and the water sample, the residual chlorine total chlorine concentration value can be determined using a residual chlorine total chlorine spectrophotometer.

Built in timer - ensures that the tested water sample and residual chlorine reagent react according to the internally set standard time. At the end of the timer, the instrument will automatically read the reading, ensuring the consistency of reaction time for multiple batches of measurements.

GLP Function - Record the date of the last user calibration execution

Error messages - warning issues on the display screen, including unlimited, out of range, and under range readings, as well as light source errors;

Automatic shutdown - measurement mode for 10 minutes, or in calibration mode, it will automatically shut down after one hour of inactivity;

Battery status - battery level indicator, 【 ▊▊▊ 】 indicates 100% battery level; 【▊▊】 indicates that the battery level is ≤ 60%; 【 ▊ 】 indicates that the battery level is ≤ 30%; When ≤ 10%, the battery icon flashes, prompting the user to replace the battery in a timely manner.
