Precision pH/mV/Conductivity/Dissolved Oxygen Multi parameter Tester P916 Instrument Purpose:
A multi parameter measuring instrument used for high-precision laboratory measurements, covering various electrochemical parameters such as pH, conductivity, and dissolved oxygen. Suitable for industries such as petroleum, chemical, pharmaceutical, power plant, and environmental protection, it has a wider range of applications in education and scientific research.
Precision pH/mV/Conductivity/Dissolved Oxygen Multi parameter Tester P916 Instrument Features:
Adopting a 6.5-inch LED screen, the parameter display is complete, intuitive, and the interface operation is designed to be user-friendly, making it convenient for users to operate and use.
Adopting Omron's long-life touch button design, it is convenient and durable, capable of reaching over 100000 times.
Compliant with international GLP requirements, it has intelligent functions such as automatic calibration, automatic temperature compensation, data storage, USB output, clock display, wireless printing, function settings, and self diagnostic information.
The instrument is equipped with a bilingual operating system in both Chinese and English, with user-friendly operation design and adjustable brightness
The built-in large capacity storage can store 2000 sets of measurement data, which can be transferred through USB storage. The stored data can be opened with the general office software EXELL for easy editing by customers.
The dissolved oxygen measurement mode has the functions of automatic temperature compensation, automatic salinity compensation, and automatic pressure compensation.
The new structure of the polarographic dissolved oxygen electrode can simultaneously measure temperature, salinity, and dissolved oxygen. Equipped with a dedicated dissolved oxygen electrode calibration kit, electrode polarization only takes 3-5 minutes.
Using a combination diaphragm cap, when replacing the sensitive membrane, simply tighten the new diaphragm cap onto the electrode, making it extremely convenient to use.
Automatically recognize 8 types of conductivity standard solutions, with two series of standard solutions to choose from: European and American series and Chinese series.
Adopting advanced conductivity measurement technology, the conductivity electrode with a constant K=1 only requires one point calibration to meet the measurement accuracy requirements of 0.5 μ S/cm~200 mS/cm.
● switchable conductivity TDS、 Salinity and electrical resistivity. TDS and salinity are calculated using polynomials to ensure full range conversion accuracy.
Automatically identify pH standard buffer solutions, with three series of standard buffer solutions to choose from: European and American series, NIST series, and Chinese series.
The instrument is equipped with a Bluetooth module that supports wireless Bluetooth printing, making it convenient for users to operate. Optional support for wireless Bluetooth transmission of data to mobile phones and computers.
Designed to meet the IP54 dust and splash protection rating.
