Overview
The HI97753 chlorides Portable Photometer is an instrument for the measurement of chlorides ion (Cl) content in water. It features High Accuracy and Rapid measurement to accurately detect chlorides content in water and is widely used for water quality monitoring and quality control. The instrument is IP67 waterproof and is designed with an innovative Optical inspection system. It features CAL CheckTM function to allow performance verification and calibrating using NIST traceability standards. Built-in Reaction Timer, GLP function to display the last calibrated date and time, as well as battery status indicator and automatic shutdown settings.
Features
1. LED high-quality Illuminant system, with good performance and high luminous efficiency;
2. High Quality Optical inspection Filter, Provides High Measurement Stability and Less Wavelength Error, Ensure Measurement accuracy and accuracy;
3. Unique reference detector for fast and stable reading between blank (zero) measurement and sample measurement;
4. Stable Illuminant Settings to Reduce Errors and Reading Offsets Caused by Defects in Glass Colorimetric Cups;
5. CAL CheckTM function.
Principle
The HI97753 photometer is based on the mercury thiocyanate (II) method for chlorides measurement. The LED Illuminant operates at a wavelength of 466nm. Absorbance is detected through a silicon Illuminant and a bandpass filter to accurately determine the chlorides ion content in water. A unique Optical inspection system and reference detector ensure fast stability and accuracy in the measurement process.
Applications
Water treatment, environment monitoring, industrial production
Standards
IP67 waterproof standard
Steps
1. Prepare the sample and ensure that the instrument is in normal working condition.
2. Use CAL CheckTM function for performance verification and calibrating (optional);
3. Put the sample into the reaction cup for measurement;
4. Built-in Reaction Timer to ensure measurement conformity;
Read and record the measurement results, the instrument automatically stores the last 50 data.
Notice
• The instrument automatically shuts down after 15 minutes of inactivity (30 minutes before reading the measurement);
• Use 1.5V AA alkaline batteries (3), Battery life about 800 measurements (no backlight);
• Ambient Temperature 0 to 50 ° C, relative humidity 0 to 100%;
• Ensure that the size of the reaction cup meets the requirements (diameter 24.6mm, inner diameter 22mm);
• Regularly verify instrument performance using the CAL CheckTM function.
