specification :

Dintok(Gmbh) designed a Compact Alarm System Called STAC dedicated for this survey.

Using an innovative and patented technology.

• Estimates the Organic Matter(COD,BOD,TOC), the TSS level and measures the nitrate concentration.
• Checks and detects undesirable substances (Pesticides, aromatic hydrocarbons.)

PRINCIPLE

Most of macro pollutants and mainly Organic Matters, TSS and Nitrates absorb in a specific way in the UV light spectrum.

By measuring the sample absorbance in the specific area of the UV spectrum, the Smart records the spectral profile of the sample, a true numerical picture of the water quality.

ADVANTAGES

• Physical method with almost no consumable
• Very fast reading (<5 minutes)
• Easy and low maintenance
• Both quantitative and qualitative reading
• Build in separates enclosures with aqueous sample isolated from electronics
• Fitting with most of tele-transmitable systems
• Fully automatic

Detector

• UV diode array spectrophotometer (204-323 nm) without any moving parts
• Easy to maintain, 50 mm quartz cuvette
• Pulsed deuterium source for a far UV high energy

Sampling

• Automatic and sequential sampling circuit rinsing and cuvette cleaning
• Programmable automatic sampling from 5 to 30 minutes
• Pinching valves Ø 8 mm for TSS reading without filtration

Date transfer

• Current loops
• RS 232
• UV-Pro software for data storage and UV spectrum management

MEASURING RANGE

Correlation with Organic Matter:

• COD: 0.2 to 8750 mg/L
• BOD: 0.05 to 8750 mg/L
• TOC: 0.1 to 7500 mg/L
• TSS: 0.5 to 2500 mg/L

Nitrates measurement
