The 31050381 is a Glass Combination pH Electrode that integrates both the measuring and reference elements into a single body. This specific model belongs to the Meredian I series, which is known for its rugged construction and compatibility with various mounting assemblies. It features a built-in Automatic Temperature Compensator (ATC) to ensure that pH readings remain accurate even as the process temperature fluctuates.
Electrode Type: Glass combination pH sensor.
Temperature Compensation: Integrated Automatic Temperature Compensation (ATC).
Operating Temperature Range: Optimized for use between $10\text{°C}$ and $80\text{°C}$ ($50\text{°F}$ to $176\text{°F}$).
Connection Type: Designed for 1.25-inch or 1.5-inch NPT connections.
Cable Length: Standard 12-foot (approximately $3.66\text{ m}$) cable with tinned leads.
Pressure Rating: Capable of operating in processes under pressure up to 50 psig.
Mounting Compatibility: Specifically designed to fit Honeywell 7774 series stainless steel insertion and removal (ball valve) assemblies.
Weight: Approximately $1.36\text{ kg}$ ($3.0\text{ lbs}$).
Accurate Temperature Compensation: The internal ATC eliminates the need for manual calculations or separate temperature probes, providing real-time corrected pH data.
Rugged Industrial Design: The glass combination design is built to withstand the rigors of industrial pipelines and tanks, offering a longer service life than standard laboratory electrodes.
Simplified Maintenance: When used with the 7774 ball valve assembly, the 31050381 can be removed for cleaning or calibration without shutting down the entire process line.
Reliable Reference System: The Meredian technology utilizes a stable reference junction that resists fouling and poisoning, ensuring consistent performance in "dirty" process fluids.
Handling Fragile Components: As a glass electrode, the sensing tip is fragile. Avoid physical impact or mechanical stress during installation to prevent cracking the glass bulb.
Hydration Requirements: The electrode must remain hydrated to function. If the bulb dries out, it may require soaking in a storage solution (typically 4.0 pH buffer or KCl) for several hours to reactivate the sensing layer.
Mounting Orientation: While versatile, the electrode should generally be mounted at least $15\text{°}$ above the horizontal plane to ensure the internal electrolyte remains in contact with the pH bulb and reference junction.
Pressure Limits: Do not exceed the rated 50 psig pressure limit. Operating beyond this specification can cause the process fluid to ingress into the electrode or cause physical failure of the sensor body.
Calibration: Regular calibration using standard buffer solutions (pH 4, 7, and 10) is necessary to account for natural sensor aging and "drift."
The Honeywell 31050381 is utilized across sectors where liquid chemistry control is vital to product quality or safety.
Water Treatment: Monitoring pH levels in industrial wastewater treatment plants to ensure compliance with environmental discharge permits.
Chemical Manufacturing: Managing acidity or alkalinity in reaction vessels and process loops to optimize chemical yields.
Power Generation: Monitoring water quality in cooling towers and boiler feed systems to prevent corrosion and scaling.
Pulp and Paper: Controlling the pH of bleaching and paper-making chemicals to maintain fiber strength and paper quality.
Food and Beverage: Used in secondary process loops or wastewater management where precise pH monitoring is required under moderate pressure.
