Measure Method

High temperature acidification digestion, all forms of mercury (including different valence, organic, complexed etc.) into the same monovalence, the total mercury content of various display color measurement of surface water and industrial wastewater in masking out other interfering ions, the results accord with the national standard GB 7469-87

Measure range

(0–0.1/0.5/1/2/5)mg/L mercury,the utility model can cover the on-line monitoring of the total mercury in the sewage or surface water discharged by any domestic sewage outfall.

Accuracy

Accuracy: <3% is far superior to the general monitor, this is because of our unique correction technology, the algorithm can achieve high sampling accuracy.

Repeatability: <3% is highly reproducible because of its unique optical quantitative algorithm.

Measurement mode

Can achieve a variety of choices, timing measurement can be realized every day at any time the user wants to start monitoring instrument; time measurement can be realized at a fixed interval every few hours start automatic measurement instrument; automatic continuous measurement of a sample measurement, can be used for product acceptance and related technical certification the manual measurement can be realized; the user site start measurement at any time, can be used for field experiments and equipment installation.

Measuring time

Can be set arbitrarily, general 15min, the technology for the domestic initiative, because the national standard method for the measurement of a sample time is fixed, the purpose is to ensure any water can be accurately measured, BQ8000 - Hg through any reaction time setting ensures that no water can obtain the accurate monitoring results.

Correction mode

Automatic timing correction or manual calibration, the calibration standard solution according to the user the actual range of the total mercury content in water samples according to the principle of proximity and configuration settings, because users need to monitor the water samples are generally restricted in a certain range, the standard solution is close to the nearest principle configuration and user actual water sample total mercury content to correct instrument large in high measurement accuracy, the same technology for the domestic initiative, a fundamental reason is better than similar domestic products.

Reagent consumption

During each measurement, each reagent consumes only 1mL, and after being measured, the reagent is discharged into a large capacity recovery container, and the overall reagent replacement time is greatly prolonged.

Instrument sampling

The injection pump, injection pump and peristaltic pump is compared with the characteristics of long service life, no aging parts such as the pump, injection pump service life with instrument for life, every year to replace a syringe on it.

Instrument external sampling

Provide submersible pump and pump in two ways, the general way for submersible pump and the ground water gap is too large (usually more than 2 meters) of the self suction pump for water, and the gap is less than 2 meters of the ground.

Maintenance cycle

If the daily measurement of 24 samples, every six months to replace a reagent, other conditions can in turn, reagent consumption cost per year is not more than 2000 yuan; according to the actual situation of water every three months cleaning a external sampling pump filter; every six months cleaning a quantitative tube or choose a replacement quantitative tube.

Pretreatment device

The pretreatment device will automatically carry out the maintenance after each measurement. Meanwhile, the pretreatment unit has a control box, which can be cleaned and maintained manually.

Two pollution

All chemical reagents are recovered, and there is no direct emissions.

Data transmission

At the same time can provide 4 - 20 mA, RS232, RS485, GPRS and other data transmission interface, in fact, by this way is actually equivalent to the product has integrated data acquisition instrument, the instrument measurement results can be directly transmitted to the Bureau of environmental protection; the need for a separate GPRS transmission mode.

Ambient temperature

+5 degrees C to +40 degrees C, requiring users to maintain water samples at the instrument installation point will not freeze, in outdoor engineering installation, need to consider the pipe insulation, to prevent winter ice, blocked water pipe.

Mechanical dimension

500 mm x 780 mm x 320 mm,The utility model can be arranged on the ground or hung on the wall separately with the pretreatment device when installed.
