Hanna HI1191T Combination Glass-body pH Electrode

Description

Robust pH Electrode for Industrial Applications

The Hanna HI1191T Combination Glass-body pH Electrode is an advanced, low-temperature industrial pH measuring component designed for continuous accuracy and resilience in diverse working environments. Featuring a double junction PTFE design combined with durable glass construction, this electrode merges precise pH sensing with maximum longevity. The PTFE junction ensures a clog-resistant performance, reducing maintenance intervals and extending operational life even in high-fouling processes. Its low-temperature glass formulation allows for rapid stabilization and dependable readings even under cooler conditions, making it highly suitable for manufacturing, processing plants, and laboratory applications that require precision when temperature fluctuations are present. The HI1191T is a combination electrode, meaning it integrates both the sensing and reference electrode elements into a single unit, which optimizes installation footprint and reduces complexity compared to separate sensors. Being compact, the 140 mm length and PG13.5 threaded section design ensure proper in-line installation without operational disruption, while enabling quick servicing.

Incorporating Advanced PTFE Junction Technology

At the heart of the HI1191T’s exceptional performance lies its exclusive PTFE non-clogging junction system. The PTFE (polytetrafluoroethylene) material resists contamination and provides stable measurements by minimizing the risk of junction fouling, which is common in many industrial applications. This feature ensures that differential pressures and sample conditions do not impair signal transmission between the sensing and reference sections. Clogging in traditional electrodes often causes drift, slow response times, and inaccurate readings. The PTFE junction in HI1191T combats these issues, offering consistent performance in high particulate environments such as wastewater treatment plants, food processing facilities, and beverage production lines. Additionally, the double-junction configuration with gel polymer filling isolates the sample from the inner reference system, significantly extending electrode life even in chemically aggressive solutions. This design makes the HI1191T reliable for applications where frequent calibration is undesirable or costly, ensuring operational continuity and stable quality control processes.

Low Temperature Glass for Accurate Results

One of the standout features of the HI1191T Combination Glass-body pH Electrode is its low-temperature glass formulation, which provides faster stabilization times during measurements in cooler conditions. Standard pH glass tends to slow response time or drift when used below room temperature, but this specialized LT (Low Temperature) glass maintains conductivity and ensures accurate pH readings from -15°C to 80°C (5°F to 176°F). This makes the electrode especially useful in refrigerated processes, environmental monitoring in cold climates, and hydroponics or aquaculture operations with seasonal water cooling. Its rapid response capability reduces testing durations and increases productivity by delivering stable readings quickly, without repeated calibration attempts. Moreover, the glass body resists thermal shock, enabling transitions between varying temperatures without compromising electrode integrity. This temperature adaptability in combination with the electrode’s robust mechanical and chemical resistance positions it as a dependable tool for industrial quality control, process monitoring, and research activities that demand certainty under varying thermal conditions.

Practical T-Type Connector for Versatile Use

The T-type connector design featured in the HI1191T offers dual advantages: the PG13.5 thread for secure in-line mounting and a screw cap interface for cable adaptation. This connector allows users to select cables of different lengths to suit plant layout, laboratory bench arrangement, or field monitoring setups. The PG13.5 threading ensures leak-free installation in standardized in-line fittings, reducing contamination risks and preserving equipment integrity. Its detachable cable capability enhances maintenance convenience, enabling easy electrode swaps without the need for cable replacement or rerouting. Such versatility is particularly advantageous for facilities with modular instrumentation setups, where rapid component interchangeability is essential for minimizing downtime. The T-type connection also enables compatibility with Hanna electrode holders and submersion assemblies, further expanding installation possibilities. Whether used in closed-loop process systems or open tank monitoring, the HI1191T’s connector design provides impeccable adaptability, reinforcing the electrode’s reputation as a technical solution for complex industrial demands.

Exceptional Durability for Harsh Environments

Designed to withstand demanding operational conditions, the HI1191T comes equipped with a glass body that resists aggressive chemicals and can endure pressures up to 3 bar (43.5 psi). The impermeable glass construction not only facilitates easier cleaning compared to plastic-bodied electrodes, but also maintains structural stability over prolonged exposure to high-energy flows or abrasive particle suspensions. Industrial processes often involve harsh environments where sensing equipment is exposed to chemical attacks, high flow rates, or mechanical shocks; this electrode’s robust build meets these challenges head-on. The double junction seal with polymer electrolyte enhances chemical resistance, preventing contamination of the internal reference by sample media. Consequently, the electrode delivers sustained accuracy and eliminates premature failures associated with single-junction arrangements. These qualities make the HI1191T ideal for industries such as pharmaceuticals, petrochemicals, environmental monitoring, and wastewater management—applications where sensor reliability directly impacts regulatory compliance and operational efficiency.

Specific Applications in Industrial Measurement

The Hanna HI1191T is engineered for a range of applications where pH monitoring must meet stringent accuracy and durability requirements. In water treatment plants, its PTFE junction ensures dependable performance even when suspended solids and biofouling are present. In food and beverage manufacturing, its low-temperature glass accommodates processes involving chilled liquids, contributing to consistent product quality. In chemical production facilities, the combination electrode design simplifies installation and maintenance while resisting aggressive chemical attack. It’s also effective in aquaculture operations, where seasonal temperature swings demand precise monitoring to protect aquatic life health and productivity. Additionally, laboratory researchers benefit from its rapid stabilization, reducing analysis time in field-sampled cold specimens. The compatibility with Hanna holders means the electrode can be adapted to either in-line or immersion configurations, providing versatility across diverse operational scopes. Industries seeking dependable pH monitoring without frequent servicing find the HI1191T an invaluable asset to their process instrumentation systems.
