Used OI ANALYTICAL 4420 #173185 for sale

OI ANALYTICAL 4420 is a laboratory-grade cross-flow membrane probe specifically designed for continuous process control and monitoring of a variety of analytes. This probe offers maximum sensitivity, accuracy, reproducibility, and reliability for a broad range of applications in industrial and academic settings. 4420 feature a stainless steel body and modular design, allowing users to customise the design in order to meet the specific requirements of any process. The device is equipped with a built-in application specific membrane that can be adapted to sample liquids such as acids, bases, solvents and aqueous solutions. The cross-flow membrane allows sample flow to go tangent to the direction of the membrane's surface, making sure that none of the analyte is retained. This probe also has a built-in electro-chemical detector which provides a signal proportional to the concentration of the analyte in the sample. This device also offers the widest dynamic range amongst OI ANALYTICAL probes, measuring from low ppb to percent level with a resolution of 0.25%. In terms of installation, OI ANALYTICAL 4420 requires an external source for power, and connection to a display device such as a computer or a tablet for data display. The probe is equipped with a proprietary connector for communication as well as display via an RS-232 or USB cable. It has a broad operational temperature range from 0°C to 50°C and can be configured with a wide range of pH and ORP membranes, allowing users to perfectly match the specific performance characteristics to the application. In terms of maintenance and operation, 4420 probe contains corrosion resistance parts and is designed to handle small solids or particulate matter in the sample. In case of regular maintenance, the user is only required to replace the membrane after a prescribed period of time, as specified by the manufacturer. OI ANALYTICAL 4420 is also exceedingly resistant to fouling and the cleaning procedure is relatively hassle-free and does not require specialized expertise. Overall, 4420 is an analytically advanced and comprehensive membrane probe which offers dependable operation, performance, and accuracy to its users. It is ideal for industrial and academic research applications as it offers accurate analysis of a variety of analytes, a wide dynamic range and a clean operation. Its simple installation and relatively easy maintenance make it ideal for both novice and experienced operators alike.
