The FC240B is a stainless steel body, single junction pH electrode that has a BNC connector. 

 

The very small 5 mm (0.2”) diameter of the FC240B is protected by an unbreakable AISI 316 stainless steel body that is 150 mm (5.9”) long; an ideal diameter is for small containers and test tubes. The FC240B also features an open junction design with viscolene gel electrolyte, a sensing bulb made of general purpose glass, and a conical tip shape.

 

This design consideration is ideal for pH measurements in cheese, dairy products, and quality control processes. The recommended operating temperature range is from 0 to 50°C.

  • Conical Glass Tip
  • Open Junction

Details

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The FC240B uses General Purpose (GP) glass, conical bulb, AISI 316 stainless steel body, and open junction with viscolene gel electrolyte.  

general purpose glass

 

General Purpose Glass Formulation

General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures. The FC240B is suitable to use with samples that measure from 0 to 50°C.

conical tip

 

 

Conical Glass Tip

The conical shaped tip design allows for penetration into solids, semi solids, and emulsions for the direct measurement of pH in food products.

stainless body

 

 


Stainless Steel Body

Having a very small diameter of only 5 mm (0.2”) this electrode can be accidentally broken. To help protect from breakage Hanna Instruments made this electrode with an unbreakable  stainless steel body. The AISI 316 stainless steel can be easily cleaned making it ideal for food industries.

open junction

   


Open Junction Reference

Suspended solids and proteins found in food products will clog a conventional ceramic reference junction. This clogging will impede the measurement circuit between the indicating electrode and the internal reference resulting in slower response time, erratic readings, and frequent electrode replacement. The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable readings.

bnc connector

 


BNC Connector

The FC240B uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. Other type of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
