Horiba Instruments Inc. is famous for the quality of its measurement devices and electrodes. The Horiba D-71 is interchangeable with any of the pH electrodes found in the Horiba pH electrode category. The full listing of pH electrodes can be found here.


The Horiba D-70 series of field and lab meters all come with the ability to connect the meter to your PC for easy data collection and storage. You can also use the meter to connect to a printer output so you can print off your data and findings directly either in the lab or the field (except for the D-71).


The Horiba D-70 series meters are among the highest quality IP-67 rated waterproof meters and electrodes available. Used primarily for water analysis, it can easily be used to test a huge range of liquid samples such as soil samples, plant sap samples, liquid fertilizers, compost tea and even your fruit and vegetable juices.


The D-70 series comprises of the following meters, all of which are available from Agriculture Solutions LLC.


D-71 - Economical meter for pH and temperature.

D-72 - Multi-parameter meter for ph/temperature/ORP with PC/printer output capability.

D-73 - Multi-parameter meter for pH/temperature/ORP/ISE with PC/printer output capability.

D-74 - Multi-parameter meter for pH/temperature/ORP/conductivity with PC/printer output capability.

D-75 - Multi-parameter meter for pH/temperature/ORP/dissolved oxygen with PC/printer output capability.


All meters are of the highest quality. None of the D-70 series meters come with electrodes allowing you to choose exactly which electrodes you prefer and easily replace old or broken electrodes without replacing the top-of-the-line meter.
