Platinum sensor pins

The HI3230B ORP sensor is made of platinum. An ORP sensor must be chemically inert so that it does not oxidize itself. It must also have suitable surface characteristics to promote rapid electron exchange. Two noble metals have proven to work well for this purpose: pure platinum and pure gold are both used in the design of ORP sensors. Platinum sensors are often preferred because they are simpler and safer to manufacture. Platinum can be welded to glass and has the same temperature coefficient. The platinum sensor signal passes through the electrode body, along with the reference signal that is conducted for measurement.

Close electrodes plasticP.E.I

The body of the HI3230B is constructed of polyetherimide (PEI) plastic. The PEI body is suitable for a wide range of applications and is highly durable. The guard around the spherical glass tip reduces the possibility of breakage due to impact or dropping. PEI is a high quality plastic that is resistant to many harsh chemicals.

Single ceramic joint

The junction, also known as a salt bridge, is an essential component of the circuit. The movement of ions must flow through the junction for a stable value. The external reference has a single ceramic frit. The ceramic is a porous material that can be easily fused to the glass body and has a similar expansion coefficient. A single ceramic junction has a flow rate of 15-20 µl/hour. Other types of junctions are available with higher flow rates and made of different materials.

BNC connection

The HI3230B uses a BNC connector. This is a universal connector that can be used on any pH meter that has a female BNC input. Hanna also offers DIN, screw, T-type, and 3.5mm connectors. Each meter typically has a unique connector that cannot be interchanged.
