AL-AC140Type total phosphorus automatic monitoring instrument

This method is suitable for wastewater with total phosphorus in the range of (0-10) mg/L. Most common ions do not interfere with the measurement, but for some samples containing a large amount of organic matter, the measurement results may be underestimated.

Mainly detecting and analyzing wastewater, aquaculture, domestic water, and total phosphorus in water quality. Applied in fields such as sewage treatment plants and chemical plants.

Main performance parameters

Main parameters and technical indicators

Measurement range 0-10 mg/L (expandable, adjustable)

Detection limit 0.01mg/L

Repeatability ≤ 5%

Zero point ≤ 0.01 mg/L

The minimum measurement cycle is 20 minutes, and according to the actual water sample, the digestion time can be modified arbitrarily within 5-120 minutes

Sampling cycle time interval (adjustable from 10 to 9999 minutes) and whole point measurement mode

Calibration cycle 1-99 days, adjustable at any interval and time

The maintenance cycle is usually once a month, about 30 minutes each time

Output RS-232, RS-485, 4-20mA (optional)

For indoor environments with adjustable temperature requirements, it is recommended to have a temperature range of+5-28 ℃; Humidity ≤ 90% (non condensing)

Power supply AC230 ± 10% V, 50 ± 10% Hz, 5A

Indication error:

± 8.0% at a standard concentration of 2.0 mg/L

± 5.0% when the concentration of the standard solution is 5.0 mg/L

± 3.0% at a standard concentration of 8.0 mg/L

memory effect

± 0.3 mg/L when the concentration of the standard solution is 2.0 mg/L

± 0.2 mg/L when the concentration of the standard solution is 8.0 mg/L

Actual water sample comparison test

Water sample concentration<2.0 mg/L ≤ 0.2 mg/L

Water sample concentration ≥ 2.0 mg/L ≤ 10.0%
