Introduction

HI83399 desktop pH-COD multi-parameter water quality meter uniquely combines electrochemical methods and colorimetric methods. It has a built-in rechargeable system and nearly 75 water quality measurement items. It has a wide range of applications and is easy to operate and carry. It is not only suitable for laboratories. It is also convenient for rapid water quality measurement on site or in the field. 

Advanced optical system

The built-in optical reference system adjusts the drift caused by power fluctuations or ambient temperature changes, ensuring that users can perform blank controls and parameter measurements under stable light source conditions.

The system uses an LED light source with superior performance, which has higher luminous efficiency, is more energy-saving, and generates less heat, thus reducing the impact on the stability of electronic optical components. The LED light source can emit light of a range of wavelengths, while the tungsten lamp is white light (visible light). ), but actually has a faint blue/violet light output.

The filter in the system makes the light source stronger and brighter, thus bringing higher measurement stability and less wavelength error. The system adds a focusing lens in the optical path to collect all the light passing through the cuvette. Gather to the silicon Detector to reduce measurement errors.

Data management

Stores up to 1,000 sets of breadth and pH data. When storing, just press the dedicated LOG button and press the RCL button to easily read back. User ID and sample information can be entered and added using the numeric keyboard. The data recording system saves GLP management programs. CALCHECK data, sample information, user ID and measurement data of each parameter.

Photometer mode

Users can switch the instrument to photometer measurement mode with a simple dedicated button. The photometer provides three measurement ranges of low, medium and high for some parameters to ensure measurement accuracy. Each measurement method corresponds to an appropriate measurement unit. Users can easily convert chemical formats and measurement units through buttons to facilitate reading. In colorimetric measurement, reaction time is crucial. A countdown reactor is built into the instrument to display the remaining time of the reading during measurement to ensure the consistency of the reading.

Backlit LCD display

Equipped with a backlit LCD display, the screen displays virtual buttons, battery level and error prompt information, and the interface is intuitive and easy to read.

Visual display

Auxiliary operation information is displayed during the operation, and user help information is available for contextual query at any time.

pH measurement

The digital pH electrode input allows the user to use an electrode to measure pH values. A built-in chip in the digital pH electrode probe stores all calibration information. The storage of this calibration information allows the pH electrode to be measured without calibration. All pH measurement values ​​are measured by The built-in thermistor located at the tip of the sensing ball is used to quickly and accurately measure temperature, and the resistor performs automatic temperature compensation.

Absorbance mode

Equipped with absorbance mode, it allows users to draw concentration and absorbance curves under specific wavelength conditions, providing users with photometric teaching principles.

Large cuvette

The measuring tank of this instrument can accept a 24.6mm round glass cuvette, and the advanced optical components can greatly reduce the measurement error. Larger cuvette test tubes can improve the light source transmission rate and ensure the measurement accuracy of low absorbance samples. At the same time, the large cuvette equipped with the instrument has a larger opening, making it convenient for users to add liquid or powder reagents.

blackout cover

The professionally designed measuring tank, black cuvette cover and instrument light-shielding cover can seal the measurement sample while preventing stray light from affecting the measurement value.
