Digital Gel Filled PEI Body ORP Electrode for Field Applications – HI36200

$165.00

The HI36200 is a PEI body, single junction ORP electrode with a built-in temperature sensor. This electrode has a single ceramic junction in the outer reference cell and the ORP sensing pin is made with platinum.


The HI36200 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes. This electrode also features a rugged PEI (polyetherimide) body that has the chemical resistance of a glass body in an unbreakable plastic making it ideal for field and industrial applications.

Details

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

The HI36200 features a platinum sensing pin, PEI body, and a single ceramic junction.

Microchip

Built-in Microchip

The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot swapping of probes without having to recalibrate. 

All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built in temperature sensor and while working in a humid environment.

Platinum Sensing Pin

The HI36200 ORP sensor is made with platinum. An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself. It must also have the proper surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two noble metals have proven to work well for this purpose: pure platinum and pure gold are both used in the construction of ORP sensors. The platinum sensor is often preferred because it is mechanically simpler and safer to produce. Platinum can be welded to glass and has the same thermal coefficient. The platinum sensor signal is carried through the electrode body, and together with the reference signal is conducted to the measurement meter.

PEI Body

The body of the HI36200 is composed of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.

Single Ceramic Junction

The outer junction of an electrode, also known as a salt bridge, is necessary component of the electrical circuit. The movement of ions must flow through the junction for a steady reading. The outer reference has a single ceramic frit.  Other junction types are available with higher flow rates and made with different materials.



 

Built-In Temperature Sensor

HI36200 features a built-in thermistor temperature sensor. A thermistor temperature sensor provides for a high accuracy temperature reading.
