Wireless Soil pH Meter HALO® - HI12922

€231.75
In stock

The HI12922 HALO is an innovative, application specific pH electrode with Bluetooth® Smart technology that allows the use of a compatible Apple or Android smart device to be used as a pH meter. This electrode is designed for agricultural, hydroponics and greenhouse growers that need to monitor the pH of soil and soiless media in order to optimize plant growth.

• Conic bulb  Easy penetration into soft solids and semi-solids

• Triple ceramic junction High flow rate for fast and stable response in slightly hydrated media

• Refillable Allows the filling of the reference cell with electrolyte fill solution

• Built-in temperature sensor High accuracy temperature compensated measurements

Conic Bulb

The conical shaped tip design allows for the easy penetration of the sensor into soft solids and semi-solids such as soil and soiless media. Soiless media includes hydroponics growing media including rockwool, coconut coir, and perlite.

Triple Ceramic Junction

The refillable HI12922 has three ceramic junctions in the reference cell. All pH electrodes have a reference junction that provides continuity between the internal reference wire and the sample. Utilizing a triple ceramic junction design allows for a higher flow rate of fill solution which helps provide for a fast and stable response in damp soil and soiless media. 

 

 

Refillable

HI12922 is a refillable pH electrode. Fill solution from the inside will diffuse through the ceramic junctions as it is used and while stored in storage solution. Electrolyte fill solution should be added to the probe when the level drops more than 1 cm (1/2”) from the fill hole in order to maintain a good flow rate sustained by having adequate head pressure (optional).

Built-in Temperature Sensor

The HI12922 has a thermistor temperature sensor built into the tip of the pH electrode. A thermistor based temperature sensor provides for a high accuracy temperature while being in the tip of the electrode allows for a rapid temperature compensated measurement.
