Hanna HI1131B Glass Body Refillable pH Electrode (BNC Connector)

The Hanna HI1131B is the world’s most popular, versatile laboratory pH electrode. Engineered with a chemical-resistant glass body and High Temperature (HT) sensing glass (up to 100°C), it features a double junction, refillable reference chamber. Terminating in a standard, universal BNC connector on a 1-meter coaxial cable, it is the undisputed OEM upgrade for 90% of benchtop and portable pH meters utilized in industrial, educational, and commercial laboratories.

Upgrade your entire laboratory testing suite with the universally trusted Hanna HI1131B Refillable pH Electrode. In commercial QA laboratories and university chemistry departments across Pakistan, technicians cycle through hundreds of different sample types a day—from highly aggressive organic solvents to thick, syrupy beverage concentrates. Cheap, gel-filled plastic probes simply cannot survive this chemical onslaught.

The HI1131B is the ultimate analytical workhorse. Forged entirely from Laboratory-Grade Glass, the body is completely immune to the aggressive solvents that melt plastic probes. It features an advanced Double Junction Reference paired with a refillable 3.5M KCl liquid chamber, ensuring rapid, incredibly stable readings that can be instantly refreshed by topping up the electrolyte. Terminating in a Universal BNC Connector, it instantly brings elite, high-temperature (up to 100°C) analytical precision to virtually any brand of pH meter sitting on your benchtop.

• Spherical Sensing Bulb: Maximizes the surface area contacting the liquid, guaranteeing lightning-fast response times during titration.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI1131B in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We supply robust, universal diagnostic probes to major pharmaceutical and educational institutions.

Q: HI1131B vs HI1131P: What is the difference?

A: The probes are identical in performance. The HI1131P features an extra metal grounding pin on the cable for specific older meters. The HI1131B features the standard, universally accepted BNC plug.

Q: Does it have an internal temperature sensor?

A: No. As a standard BNC electrode, it measures pH only. If you need Automatic Temperature Compensation (ATC), you must use a separate thermal probe.
