Honeywell Electrode

Honeywell Electrode 7774pH ORP The electrode insertion removal device has good quality.
First, the pH electrode must immersed in the process solution at least 5.08 cm (2 in.) .

And allow for insertion depth from the outside wall of the mounting surface as indicate thedimensions in Figure 3-1. If vertical insertion (from above) is used, assure that the tank or pipeline is full under all process conditions.

If a pipeline is not always full, use a vertical mounting and insert the electrode far enough into the pipe. The electrode tip is at least 10.6 cm (4 in.) below the horizontal exit pipe which may empty out. Toassure a good reading, assure that air space will not interfere at the point of measurement.

Second, suspended solids The electrode can mount in any position. And it recommend that the removal device mount suchthat the electrode point downstream in the direction of flow when suspende solids may be present.

If the electrode must be mount pointing upstream, against the direction of flow, the tip may becomeclogged. In applications where vertical mounting required, avoid a position with the electrode pointed up as thiswill permit clogging by solids settling in the tip area.

Then, rquirement for circulation of solution around electrode Allow at least 12.7mm (1/2 in.) clearance beyond the end of the electrode and 3.2 mm (1/8 in.) to4.8 mm (3/16 in.) radius clearance surrounding the electrode to permit circulation of the solution.

Operating Range:0-14pH
Preamplifier Module weight:Approximately 0.9 kg (2 lbs)

Honeywell Electrode

Honeywell Electrode 7777 Meredian type pH ORP Combination Electrode is original.
Honeywell’s 7777 Series of electrode mountings enables an user to interface Durafet II pH electrodes to a process via a ¾” threaded connection and Meredian II by either submersing the electrode or mounting it into a ¾” threaded connection.

Durafet II pH electrodes are the first industrial ISFET-based pH sensors. They join Honeywell’s industry-proven glass pH electrodes in the 7777-Series mounting to provide accurate and dependable pH measurement.
Description
The Durafet II and Meredian II pH electrodes offer a reliable combination of measuring and reference electrodes together with an integral automatic temperature compensator in a 1-piece corrosion-resistant molded Ryton body.

Quick disconnect plugs enable easier installation and maintenance than with any other electrode available. The compact electrodes with 3/4” NPT male connections are easily adapted for in-line mounting without O-rings or special seals. Meredian II is also available in Immersion and
On-line

The large surface area of the reference junction resists fouling and maintains reliable lowimpedance contact with the process solution. The reference junction’s symmetrical annular shape surrounding the measuring element minimizes the effects of electrical current passing through the process solution.

This offers a significant improvement when compared with unsymmetrical electrode designs that develop large offset potentials and prohibit pH measurements in applications such as electroplating tanks or electrolytic cells. Durafet II Combination Electrodes feature state-of-the-art pH
measurement technology, using an ISFET (Ion Sensitive Field Effect Transistor) sensing element.

What Is It?
​The HB and HBD Series use a unique reference technology measurement. The HBD Series incorporates the non-glass Durafet sensor with a unique reference design.

​The reference technology prevents poisoning, internal plugging and internal leakage. Complete filling of reference body allows extreme temperature and pressure tolerance.

The HB and HBD Series is available in three designs. They use different threaded connections for easy installation depending on the process. For in-line or submerged operations, the 546 uses a ¾-inch MNPT threaded nose, while the 551 used as a quick change sensor includes a 1-inch MNPT threaded adapter for installation. The 551 sensor comes with a nut-loc retainer for quick removal and replacement.

The 547 is available with a 1-inch MNPT Wrench-tite, or 1-1/4-inch MNPT Hand-tite compression fittings.

What Problems Does It Solve?
​Honeywell’s HB and HBD Series of pH electrode mountings series is the preferred choice for applications involving high temperature, high pressure and aggressive chemical compositions. Rugged materials such as CPVC, Polypropylene and Kynar make these electrodes strong and virtually unbreakable.

Designed for applications involving high temperature, high pressure and harsh chemical conditions, Honeywell’s HB Series of pH electrode mountings provide a solution for all pH needs, along with Meridian glass pH electrodes and Durafet® non-glass electrodes. The electrode assembly in the pH electrode mountings is constructed with rugged materials such as CPVC, Polypropylene and Kynar.

The HBD Series is best suited for the harshest conditions, providing long life as compared to traditional pH.
