SKU:HI4000-51

The HI4000-51 replacement pH reference assembly is for use with Hanna’s HI4101 ammonia gas sensing ion selective electrode (ISE). This internal glass pH assembly provides the sensing and reference components for the ammonia combination ISE.

Theory of Operation

A gas sensor works due to the partial pressure of the measured gas in solution. The dissolved gas in the sample diŽffuses into the membrane and changes the pH in a thin film of unbuffered electrolyte on the surface of the internal pH sensor. Diffusion continues until the partial pressure of the sample and the thin film of electrolyte are the same. The pH change is proportional to the concentration of dissolved gas in the sample solution.

Digital PEI Body pH Electrode with Matching Pin for Field Applications - HI12301

481 AED
The HI12301 is a plastic body, double junction, gel filled pH electrode with a matching pin and built-in temperature sensor for temperature compensated measurements in a single probe design. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes. The matching pin integrated into the HI12301 is for the Sensor Check™ capability of the edge pH meter; this feature is used to identify problems with the pH electrode such as cracks in the sensing glass or poor condition of the reference junction. The HI12301 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features a single ceramic junction and the spherical pH sensing portion is made with low temperature glass. The electrode has a rugged PEI (polyetherimide) body that has the chemical resistance of a glass body in an unbreakable plastic making it ideal for field and industrial applications.
  • Matching Pin for enabling Sensor Check feature that alerts to a broken electrode or clogged junction
  • Double Junction Reference
  • 3.5 mm Connector

HI12883 pH/EC/TDS Multiparameter Probe with Quick Connect DIN Connector

583 AED
The HI12883 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance free polymer gel electrolyte, and a low temperature glass sensing bulb. The EC/TDS portion of this probe utilizes two graphite sensors for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples. The design consideration for the HI12883 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, environmental monitoring, water treatment, wastewater treatemnt and boilers and cooling towers. The HI12883 is designed for use with Hanna’s HI991300 and HI991301 portable multiparameter meters.
  • Pre-amplified pH electrode
  • Amperometric EC/TDS sensor
  • Built-in temperature sensor
