Hanna Instruments-13302 HALO® Wireless pH electrode for Vials and Test Tubes
Low-Temperature Glass Formulation
The Hanna Instruments-13302 is suitable to use with samples that measure from -5 to 70°C.
Spherical Bulb
The spherical bulb is for general purpose use. Other tip shapes include conic for penetration and flat tip for surface measurements.
Tapered Glass Body
The narrow glass body is ideal for laboratory use, specifically with test tubes and vials. The glass is resistant to many harsh chemicals and can be easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.
Single Ceramic Junction
The outer junction of an electrode, also known as a salt bridge, is a necessary component of the electrical circuit. The movement of ions must flow through the junction for a steady reading. A single ceramic junction has a flow rate of 15-20 μL/hour. Other junction types are available with higher flow rates and are made with different materials.
Hanna Instruments-13302 HALO® Wireless pH electrode for Vials and Test Tubes
The Hanna Instruments-13302 HALO® is a slim glass pH electrode that incorporates Bluetooth Smart (Bluetooth 4.0) wireless technology with an application-specific design. It has many features that make it ideal for use in laboratory applications, especially when using vials and test tubes. These features include low temperature (LT) glass, tapered glass body, and single junction with 3.5M KCl + AgCl electrolyte.
- Fits easily into vials and test tubes, 3mm tip
- Visible from a distance, the LED “halo” light flashes to indicate its status.
- The HALO’s CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours
- Just one click and the electrode will connect to a tablet or mobile phone through the Hanna Lab App or the edge® blu.
