pH & conductivity continuous indicator.
HI-981405N Gro'chek Combo pH & conductivity continuous indicator
The HI-981405N features separate displays for continuous readout of both pH and conductivity. The meter uses a 12volt power source from the mains using a 12volt transformer which is included in the price of the instrument.
Supplied with both the pH electrode and the conductivity probe, the meter also has an earthing pin to ensure that readings are correct and not affected by a lack of earth within a plastic or other form of insulated tank environment.
The pH electrode is replaceable and the BNC connector is protected behind a waterproof sheath when connected to the meter. Both the pH and the conductivity readings are automatically compensated for temperature thus removing the need to convert the readings, or the risk of an incorrect result.
Calibration : EC 1.41 Buffer
Calibration : pH 4 Buffer & pH 7 Buffer
