HI12302 – HALO® PEI Body Gel Filled pH Electrode with Bluetooth®

The HI12302 HALO is a Bluetooth Smart (Bluetooth 4.0) pH and temperature electrode with a durable PEI body and spheric, low temperature glass sensing bulb.

The double junction design ensures that the gel electrolyte is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell, resisting clogging and any potential precipitation at the junction.

All readings are transmitted directly to the HI2202 edge^blu or a compatible Apple or Android device running the Hanna Lab App.

One Press Connect

Easily connect to the Hanna Lab App at the press of a button via Bluetooth wireless technology.

Status Indicator

Visible from a distance, the LED “halo” light flashes to indicate the status of the probe.

Easy-to-Replace Battery

The HALOs CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours.
