-
3 sensors in a single probe
-
Gel filled maintenance free pH electrode
-
Amplified pH electrode
-
Polypropylene body – The body houses all the sensors in a single body design and is durable. The probe is gel filled for maintenance free operation. It does not have to be refilled periodically.
The specially engineered HI1285-7 pH/EC/TDS/temperature electrode utilises a fibre junction and gel electrolyte which provides a fast response and reduced potential for contamination.
These features make this probe ideal for use in fertiliser solutions.
A solid-state preamplifier is integrated into the probe to protect the pH measurement from transient electrical noise. Sources of electrical noise include ballasts used in lighting and pumps to circulate water and nutrient solutions.
The HI1285-7 probe features a Quick Connect DIN connector that makes a waterproof connection with the meter.
Recommended for use with the HI9814 Groline pH/EC/TDS/Temperature Meter.
