Overview
TR-ZH portable STIP-scan is developed and designed based on national standards such as GB7466-87, GB7467-87, GB11910-89, and adopts imported cold light source and narrow-band interference technology. Absorbance of samples is detected by Spectrophotometric method, spectra-trophotometry, and concentration value (mg/L) is directly displayed after microcomputer treatment. The instrument adopts digestion Colorimetric integrated tube, which has the characteristics of small and portable, fast detection, simple operation and low cost. It is widely used in emergency monitoring, sewage treatment, chemical industry, food and other industries wastewater detection and research and use in scientific research institutions.

Standards
GB7466-87 "Water Quality, Determination of Total Chromium", GB7467-87 "Water Quality, Determination of Hexavalent Chromium, Diphenylcarbazide Spectrophotometric method, spec-trophotometry", "Dicyclohexanone Oxalyl Dihydrazone Method", GB11910-89 "Water Quality, Determination of Nickel, Dibutanedione Oxime Spectrophotometric method, spec-trophotometry", "Xylenol Orange Spectrophotometric method, spec-trophotometry", HJ/T345-2007 "Water Quality, Determination of Iron, o-phenanthroline Spectrophotometric method, spec-trophotometry"
Steps
1. Select the corresponding reagent and Measurement mode according to the detection parameters.
2. Sample Handling and Determination using Digestion Colorimetric Tubes.
3. The instrument automatically detects Absorbance and processes the data.
4, directly read the concentration value displayed on the screen.
5. You can choose to store data or transfer it to a PC or printer through the interface.
Notice
• Please read the general precautions of the built-in help interface carefully before operation.
• Ensure that the environment temperature is within the range of 5~ 40 ° C, and the humidity is ≤ 85% without condensation.
• Use specialized detection reagents to reduce operating errors.
• Pay attention to the remaining power display of the instrument and charge it in time.
• When digesting, the temperature and time should be controlled according to the parameter requirements (for example, the total chromium needs to be digested at 125 ° C for 30 minutes).
• Avoid use in strong electromagnetic interference environments.
• Periodically check Optical inspection Stability to ensure Measurement accuracy.
