HI-981401N pH Indicator information

Hanna's extended description

The housing of the HI-981401N is water resistant and features a moulded eye which allows installation right above the sample to be monitored.

Measurements are highly accurate and can be verified with two point calibration. With a 12 VDC power supply included with the meter, low battery failures are never an issue.

The electrode is interchangeable and the connector is well protected behind a waterproof sleeve. The meter is supplied with a stainless steel probe, preventing potential grounding problems and ensuring extended electrode life.

The gel-filled pH electrode has been specially designed to address the needs of growers. Its design guarantees greater clogging resistance in fertiliser solutions with high concentrations of nutrients such as phosphate and nitrate.

About the electrode

The meter is supplied with a HI-1286 pH probe with a PEI body and BNC Connector. This double junction, gel-filled combination pH electrode has a unique PTFE sleeve to prevent particulates within a sample from clogging the junction. In addition to the specialised junction, the polyethylenimine (PEI) protective body protects against most aggressive chemicals as seen in fertiliser solutions with high concentrations of phosphate and nitrate.

BNC Connection – BNC is one of the most commonly used connector types in pH meters and electrodes. Compatible with any meter or electrode that uses BNC connectors.

Replaceable Electrode – No need to replace the whole meter when the electrode needs replacing. Spare and replacement electrodes are available for this product.
