Designed for water professionals
High purity water used in power generation, semi-conductor manufacturing, and other industries can be difficult to measure due to the ability of carbon dioxide (CO2) to diffuse into water and form carbonic acid (H2CO3).
Carbonic acid quickly dissociates into hydrogen ions (H+) and bicarbonate ions (HCO-3). These ions will increase the conductivity and decrease the resistivity of the water. In order to measure high purity water accurately, it is necessary to perform a continuous flow measurement.
HI-98197 uses the HI-763123 four-ring probe with a threaded connection that is screwed into a stainless steel body flow cell. The flow cell is then connected to a water source to more accurately determine the conductivity or resistivity without exposure to air. Hi-98197 is an ideal meter for monitoring the efficiency of a mixed bed resin or equivalent system that produces high purity water of 18.2 MΩ•cm at 25°C.
Backlit Graphic LCD Display
The HI-98197 features a backlit graphic LCD with on-screen help. The graphic display allows for the use of virtual keys to provide for an intuitive user interface.
Quick connect probe
The HI-763123 four-ring platinum conductivity probe with a threaded connection features a quick connect DIN connector to make attaching and removing the probe simple and easy.
Waterproof protection
The meter is enclosed in an IP67 rated waterproof casing and can withstand immersion in water at a depth of 1m for up to 30 minutes.
Calibration
Choose from seven memorised standards and obtain up to a five point conductivity calibration. For salinity (% range), HI-7037 standard allows users to perform a one point calibration.
Measurement
EC and TDS measurements are fully customisable and include: cell constant selection between 0.010 and 10.000, selection of linear or natural water (non-linear) or no temperature compensation (for actual conductivity reading), configurable temperature compensation coefficient range from 0.00 to 10.00%/°C, choice of reference temperatures of 15°C, 20°C and 25°C, and a selectable TDS factor between 0.40 and 1.00.
Ten sets of customised measurement parameters can be stored as a user profile and later recalled.
Autohold
Pressing Autohold during measurement will automatically hold the first stable reading on the display.
USP <645>
HI-98197 can be used to perform all three stages of USP <645> method required for EC measurement of water for injection and generates a report when any of the three stages are met. An on-screen guide instructs on each USP stage. A progress bar displays reading stability progress towards meeting stage 2 requirements.
Data logging
The HI-98197s allow storage of up to 400 log-on demand samples or 1000 lot logging samples that can be later transferred to a PC with the supplied HI-920015 USB cable and HI-92000 software.
GLP
Comprehensive GLP functions are directly accessible by pressing the GLP Key. Calibration data, including date, time and calibration values are stored for retrieval at a later time.
Intuitive keypad
The fitted rubber keypad has dedicated keys for power, backlight, up/down arrows, help and alphanumeric characters. The meter also features two virtual soft keys that navigate the user through the configuration of each parameter, meter setup, and logging of data. The interface is intuitive for any user’s level of experience.
Dedicated help key
Contextual help is always available through a dedicated HELP key. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.
Setup screen
Our extensive setup screen features a host of configurable options such as time, date, temperature units and language for help screens and guides.
PC Connectivity
Logged data can be transferred to a Windows compatible PC with the included HI-920015 micro USB cable and HI-92000 software.
Long Battery Life
The display of the meter has a battery icon indicator to show the remaining power. The meter uses four 1.5V AA batteries that provide up to 200 hours of battery life.
