LabSen803 Professional 3-in-1 pH/Temp. Electrode for Purified Water

Prekė gali skirtis nuo prekės, parodytos nuotraukoje

 

The LabSen® 803 from Apera Instruments is a pH electrode with integrated temperature sensor and is manufactured using proprietary Swiss sensor technology and materials. It is specially designed for pH measurement of pure water like drinking water, distilled water, etc.

LabSen L-type glass membrane - The electrode features a special cylindrical glass membrane that is up to 10 times more robust than conventional products and is particularly suitable for solutions with low ion concentration due to its very low resistance (<50MΩ). It provides fully stabilized readings after only 30 to 60 seconds.

Movable sleeve - The easy-to-clean diaphragm sleeve allows the infiltration rate of the electrolyte to be adjusted and thus adapted to the ion concentration of the sample.

Silver Ion Trap Reference System- The LabSen 803 pH electrode uses a silver ion trap reference system that is added to the long life reference system to prevent the compound from being blocked by silver sulfide.

Patented pH/temperature combination structure - The temperature element is placed in an independent cavity under the pH glass membrane. With the built-in thermally conductive medium, the temperature measurement can be 40% faster, which significantly improves the reaction time and stability of the pH electrode.

• pH sensor technology and materials from Switzerland
• LabSen L-type glass membrane especially for low ion concentrations
• Blue gel electrolyte, does not flow and does not cause air bubbles
• Adjustable infiltration rate of the electrolyte via movable sleeve
• Silver ion trap prevents blocking by silver sulfide
• Integrated temperature sensor enables automatic temperature compensation

The electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. The integrated temperature sensor is connected with an RCA connector (Cinch) and is not compatible with all measuring devices of other manufacturers. The LabSen 803 is the replacement electrode for the PH850-PW and PH8500-PW from Apera Instruments.
