PH/Conductivity Dual Parameter Tester P904 Instrument Purpose:
Suitable for high-precision pH and conductivity measurement in fields such as scientific research, quality control, biotechnology, fine chemicals, acid-base titration, etc.
PH/Conductivity Dual Parameter Tester P904 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 built-in large capacity storage can store 500 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.
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.
Intelligent judgment of electrode status to ensure accurate application for customers.
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.
