Overview
The TR-105H water quality hexavalent chromium tester is developed and designed based on the GB7467-87 standard. It adopts the diphenylcarbazide Spectrophotometric method, spectrophotometry, and reacts with hexavalent chromium through Color developing reagent, chromogenic agent to generate a purplish-red complex. Absorbance is determined by imported cold light source and narrow-band interference technology, and the hexavalent chromium content (unit mg/L) is directly displayed by microcomputer treatment. The matching finished reagent makes the detection simple, fast, accurate and safe. It has the characteristics of small appearance, rapid detection, easy operation and low cost. It is widely used in emergency monitoring, sewage treatment, chemical industry, food and other industries wastewater detection and research institutions.
Features
1. Wide detection range: can expand dozens of detection parameters, support customization.
2. Sensitivity: the minimum display value is 0.001mg/L.
3. Light source advantages: imported cold light source, good Optical Property, no need to preheat, life 100,000 hours.
4. Operational intelligence: Intelligent programs guide users to operate with ease.
5. Diversified test methods: Support standard measurement or continuous Measurement mode.
6. Low cost of use: low price of consumables and low usage.
7. Operation safety: Colorimetric integrated tube is used for simple, fast and safe determination.
8. Large-screen LCD display, direct data reading, time-saving operation.
9. Emergency detection advantages: compact and portable, with special reagents, support for wireless Bluetooth printing, can store 4000 sets of data, and built-in large-capacity lithium battery.
10. Online function: Support network port, USB, Bluetooth and PC or printer data transmission.
11. Software advantages: Chinese and English display, built-in system/user programs, data storage and power-off protection, built-in standard working procedures, user-customizable programs and reagents, help interface, one-click factory reset.
Principle
The instrument is based on the Spectrophotometric method, spectra-trophotometry, Color developing reagent, chromogenic agent, which directly reacts with hexavalent chromium to form a purple-red complex. Absorbance is determined by imported cold light source and narrow-band interference technology, and then the hexavalent chromium content is directly displayed after processing and calculation by microcomputer chip.
Applications
Emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing and other industries wastewater testing, R & D institutions, wastewater research in colleges and universities
Standards
GB7467-87 "Water Quality, Determination of Hexavalent Chromium, Diphenylcarbazide Spectrophotometric method, spec-trophotometry"
Steps
1. Prepare samples and supporting reagents.
2. Select Measurement mode (Standard or Continuous).
3. Use digestion Colorimetric tube for determination.
4. The instrument automatically processes and displays the hexavalent chromium content.
5. Data can be stored or transmitted through an interface.
Notice
• Read the help interface precautions before operation.
• Ensure that the environment temperature is 5~ 40 ℃, humidity ≤ 85% without condensation.
• Use matching reagents to reduce operating errors.
• Regularly check the battery level to ensure stable power supply.
• Avoid direct exposure to strong light and keep Optical inspection parts clean.
• Backup data in time after storage to prevent accidental loss.
• User-defined programs must follow standard methods.
