Hanna HI4013-53 Nitrate Module for Half-Cell ISE
The Hanna HI4013-53 Nitrate Module for Half-Cell ISE is a replacement sensor designed for the HI4013 nitrate half-cell ion-selective electrode (ISE). This module features a liquid membrane sensor that incorporates an organic polymer within an inert PVC matrix, allowing selective measurement of nitrate ion activity in aqueous solutions.
Each HI4013-53 sensor provides stable, reproducible potential changes in response to nitrate ion concentrations, making it suitable for applications in environmental testing, agriculture, and water quality control.
Features
Accurate Nitrate Sensing: Measures nitrate ion activity via ion exchange across a liquid membrane embedded in PVC.
Modular Design: Easily screws onto the HI4013 half-cell probe body for quick replacement and minimal downtime.
Enhanced Measurement Performance: Presoaking the sensor in a dilute standard without ISA improves response time and accuracy.
Extended Sensor Life: Refrigeration when not in use helps preserve membrane performance over time.
Economical Pack: Supplied as a 3-piece set, ideal for labs that require regular sensor replacements.

Application Guidelines
Installation: Attach the HI4013-53 module to the HI4013 half-cell body by simply screwing it into place.
Calibration Preparation: Prior to calibration, soak the module in a dilute nitrate standard (without ISA) for at least 30 minutes.
Measurement Tips: For optimal accuracy, use with nitrate calibration standards such as HI4013-01, HI4013-02, or HI4013-13, and always add the proper amount of ISA (HI4013-00) during actual measurements.
Maintenance: Store the module in a cool, dry place (preferably refrigerated) when not in use to preserve its functionality.
Applications
This nitrate module is suitable for a wide range of applications, including:
Environmental Testing: Monitoring nitrate levels in surface water, lakes, and groundwater.
Agricultural Analysis: Measuring nitrate in fertilizers and soil extracts.
Water Quality Control: Testing drinking water and industrial wastewater for nitrate contamination.
Research and Education: Supporting ion-selective analysis in academic and laboratory settings.
