Description
Turbidity and chlorine, which are two of the most crucial elements in drinking water, are measured by the multiparameter device known as the HI93414. The gadget uses a cutting-edge optical technology to minimize stray light and color interferences and deliver accurate readings. Any changes in the tungsten lamp’s intensity are offset by routine calibration using the provided standards.
In order to preserve the correct wavelength for the measurement of free and total chlorine, the colorimeter part of the meter uses a 525 nm narrow band interference filter. To achieve the highest level of repeatability for turbidity and chlorine measurements, all measurements are carried out using 25 mm round cuvettes made of specialized optical glass.
Features at-a-glance:
Three Measurement Modes – The HI93414 features three options for measurement including ratio mode for turbidity, free chlorine, and total chlorine. Turbidity measurements can be made in the 0.00 to 1000 NTU (Nephelometric Turbidity Units) range, while free or total chlorine measurements can be made in the 0.00 to 5.00 mg/L (ppm) range.
Multiple reading modes – Normal measurement, continuous measurement, or signal averaging measurement are reading modes available
EPA Compliant – The HI93414 meets and exceeds the requirements of EPA and Standard Methods both for turbidity and colorimetric chlorine measurements. When the meter is in EPA mode all turbidity readings are rounded accordingly to meet reporting requirements.
Calibration – A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.10, 15.0, 100, and 750 NTU) standards. Calibration points can be modified if user-prepared standards are used. For free and total chlorine, the 1.00 mg/L (ppm) CAL Check™ standard can be used for calibration and performance verification.
AMCO AEPA-1 Primary Turbidity Standard – The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.
CAL Check™ – With the powerful CAL Check™ function, reliable performance of the chlorine colorimeter can be validated at any moment by using the exclusive HANNA ready-made, NIST traceable standards. All standards are supplied with a Certificate of Analysis (COA) for traceability.
Fast Tracker™ – For advanced field applications, the HI93414 is equipped with Fast Tracker™ – Tag Identification System (T.I.S.) that makes data collecting and management simpler than ever. Fast Tracker™ allows users to record the time and location of a specific measurement or series of measurements using iButton® tags near sampling points for quick and easy readings. Each iButton® tag contains a computer chip with a unique identication code encased in stainless steel.
GLP Data – The HI93414 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.
Data Logging – Up to 200 measurements can be stored in the internal memory and recalled at any time.
Data Transfer – For further storage or analysis options, logged data can be downloaded to a Windows compatible PC using the RS232 or USB ports and the HI92000 software.
Backlit Display – A backlit LCD display provides an easy to understand, user-friendly interface. Displayed codes guide the user step-by-step through routine operation and calibration.
- The applicable range is 0-40 nephelometric turbidity units (NTU)
- Light source: Tungsten lamp operated at a color temperature between 2200-3000°K.
- Distance traversed by incident light and scattered light within the sample tube: Total not to exceed 10 cm.
- Detector: Centered at 90° to the incident light path and not to exceed ±30° from 90°. The detector, and filter system if used, shall have a spectral peak response between 400 nm and 600 nm
- The sensitivity of the instrument should permit detection of a turbidity difference of 0.02 NTU or less in waters having turbidities less than 1 unit.
- Report results as follows:
| NTU reading | Rounded to nearest |
| 0.0 – 1.0 | 0.05 |
| 1 – 10 | 0.1 |
| 10 – 40 | 1 |
| 40 – 100 | 5 |
| 100 – 400 | 10 |
| 400 – 1000 | 50 |
| >1000 | 100 |
The HI93414 meets and exceeds the meter criteria specied by the EPA Method 180.1 and Standard Methods for the Examination of Water and Wastewater 2130 B.
