Hanna HI1131P Glass Body Refillable pH Electrode (BNC + Pin)

The Hanna HI1131P is an elite, laboratory-grade pH electrode designed for general-purpose high-temperature testing. Constructed with a chemically resistant glass body, it features a double junction reference to prevent silver precipitation and utilizes High Temperature (HT) glass capable of withstanding up to 100°C. Its defining feature is the BNC + Pin connector, designed specifically for Hanna meters that utilize a differential input to eliminate electrical noise.

Execute flawless, high-temperature laboratory chemistry with the Hanna HI1131P Refillable pH Electrode. In complex analytical laboratories, testing aggressive solvents or actively boiling liquids destroys standard pH probes. The high heat physically alters the resistance of standard sensing glass, causing massive mathematical errors in the pH reading.

The HI1131P is explicitly forged for extreme thermal environments. The sensing bulb is constructed from specialized High Temperature (HT) Glass, which maintains perfect electrical resistance up to 100°C (212°F). To prevent the internal reference from clogging, it utilizes a Double Junction Design paired with refillable 3.5M KCl (silver-free) electrolyte. The most critical aspect of this probe is its BNC + Pin Connector. The extra metal pin serves as an electrical ground matching pin, which is absolutely mandatory for specific Hanna benchtop meters (like the classic HI2211) to actively cancel out static and electrical noise during testing.

Key Features:

• BNC + Pin Connector: Provides the mandatory grounding pin required by specific legacy and specialized Hanna benchtop meters to block electrical interference.
• High Temperature (HT) Glass: Prevents the rapid degradation and erratic readings caused when testing boiling liquids and hot industrial solvents.
• Refillable Economy: Drastically extends the lifespan of the probe; when the readings get sluggish, simply flush the chamber and refill with fresh HI7082 electrolyte.
• Double Junction Protection: Prevents heavy metals and sulfides from poisoning the internal reference wire, completely preventing junction clogging.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI1131P in Pakistan?

A: Visit Kamadi.pk for current corporate pricing. We supply authentic OEM Hanna replacement probes to major chemical and educational laboratories.

Q: Will this fit a standard BNC meter?

A: If your meter only has a BNC port and no secondary pinhole port next to it, the grounding pin on this cable will physically block you from plugging it in. You must buy the HI1131B instead.

Q: Is the glass body breakable?

A: Yes, it is laboratory-grade glass. It is highly resistant to aggressive chemicals, but it must be handled carefully on the benchtop to avoid physical impacts.
