Articlename: AZURA pH sensor, 100 ml/min

AZURA pH sensor, 100 ml/min


for conductivity monitor CM 2.1S, for flow rates up to 100 ml/min delay volume ~ 80 µl, max. pressure 5 bar

The AZURA pH sensor is an optional accessory that can be connected to the CM 2.1S conductivity monitor. It comes with a pH electrode with BNC connector, a pH flow cell with integrated bypass, and flat-bottom fittings to connect the pH flow cell to either 1/16" or 1/8" OD tubing. 

 

Several options are available to physically integrate the sensor into your AZURA system to minimize system volume. Choose from the AZURA Mounting Bracket Bio, the AZURA Organizer, or the AZURA Click System (ordered separately).

Order the pH electrode dummy separately if your application requires frequent removal of the pH electrode.

 

The recommended maximum flow rate is 100 ml/min, however the pH sensor tolerates higher flow rates. the limiting factor is the maximum pressure of the pH electrode (5 bar). The delay volume of the flow cell with inserted electrode is approx. 80 µl.
