ISE Incremental Methods
The HI6000-2 module features incremental methods for Ion Selective Electrode applications. Known Addition, Known Subtraction, Analyte Addition, and Analyte Subtraction are versatile methods for the measurement of ions in aqueous samples from environmental, agricultural, industrial, biotechnical, pharmaceutical, food, wastewater, and drinking water. These methods offer stepwise guidance for ion analysis and are ideal for complex or high ionic strength samples as the electrodes remain immersed throughout the process, making analysis faster and more accurate.
EC USP Mode
The HI6000-3 EC module can be used for conductivity measurements required to prepare water for injection (WFI) according to USP <645>. The system provides clear instructions on how to perform each stage and automatically checks that the temperature, conductivity, and stability are within USP limits.
The Direct/USP mode is a special mode with specific measurement settings defined by the United States Pharmacopoeia Regulations and European Pharmacopoeia. The process involves three parts: Meter Validation with precision resistors, Cell Verification with conductivity standard, and Stage 1, 2, and 3 water tests. The results of each test are recorded in a report that includes information such as company name, date and time, instrument ID, operator ID, sample ID, module types used, calibration details, and test results.
Recommended Probes
pH/ORP/ISE Probes
The HI1131B is a glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass. The double junction reference and HT glass design allow the electrode to be used in a wide variety of applications including samples with metals and elevated temperatures. Probe connection to the unit is secured through a galvanically isolated BNC connection. The HI7662-TW stainless steel temperature probe allows the meter to automatically temperature compensate (ATC) pH measurements.
Conductivity Probe
The HI7631233 four-ring conductivity/resistivity/TDS/salinity probe is recommended for a wide range of industrial process water applications. The probe provides stable measurements over a wide measurement range and does not require frequent calibrations. An integral temperature sensor measures the process temperature and adjusts the measured conductivity to a reference temperature by applying specialized compensation algorithms: Linear, Standard (appropriate for high-purity water measurements and documented in ASTM Standard D5391-14, should be used for >1Mohm.cm resistivity measurements), and Natural (appropriate for natural ground, well, or surface water in accordance with ISO7888 standard).
Dissolved Oxygen Probes
HI7641133 Optical Dissolved Oxygen Probe (opdo®): Based on the principle of fluorescence quenching. An immobilized Pt-based luminophore is excited by the light of a blue LED and emits a red light. As oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence. The lifetime of the luminescence is measured by a photodetector and is used to calculate the dissolved oxygen concentration.
The probe is fitted with easy to use Smart Caps (HI764113-1) which lock in place and contain pre-loaded calibration coefficients that are automatically transmitted to the probe. The Smart Cap features an immobilized O₂ sensitive luminophore with rugged insoluble black oxygen permeable protective layer. Over time, the sensor's optical components can age but are compensated for by using the reference signal to compensate the measuring path. As a result, the sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.
HI764833 Polarographic Probe: The slim and versatile polarographic probe covers a wide range of dissolved oxygen and has a built-in thermistor temperature sensor that compensates for temperature variations. The slim design allows for convenient measurement in test tubes and Biological Oxygen Demand (BOD) bottles. Durable and robust, the probe features a platinum cathode and Ag/AgCl anode assembly. Accurate and with a fast response time. The probe is fitted with durable (PTFE), oxygen permeable, screw on membrane caps. Caps are filled with electrolyte and easily install on the probe.
Concentration measurements are automatically compensated for barometric pressure, temperature, and salinity. Barometric pressure and temperature are automatically measured and compensated. Salinity is automatically compensated by setting manually the salinity concentration of the water being measured. Pressure compensation is done automatically (built-in barometer) or users have the option to manually enter required value. Pressure is displayed in user-configurable units: mmHg, mbar, kPa, inHg, psi, atm.
Salinity Measurement
TDS: A calculated value based on the conductivity of the solution (TDS = factor x EC25). A TDS factor is a conversion factor used to change an EC measurement to a ppm measurement.
Salinity PSU: The
