Hanna Instruments-14142 HALO® wireless pH electrode for flat surface measurements
The Hanna Instruments-14142 HALO® wireless surface pH meter incorporates Bluetooth® Smart technology. There are several features that make it ideal for measuring pH:
- Easily measures pH on flat surfaces, or small volume samples, with the specially designed sensing 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.
Flat Glass Tip
A flat tip optimises surface contact for measurement on flat surfaces such as agar plates, skin, leather, paper, and samples that cannot easily be penetrated.
Glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte allowing temperature compensation to happen rapidly leading to a steadier reading.
Open Junction Reference
The open junction design uses a solid gel interface between the sample and internal reference cell. This interface prevents silver from exiting the junction, but also makes it impermeable to clogging, resulting in a fast response and stable readings. The design allows for smaller sample sizes as there is no junction to submerge
