Overview

HU-200SS on-site installation MLSS instrument (four wire transmission) is connected to an immersion MLSS sensor (SS-90) and measures MLSS in activated sludge. The use of near-infrared radiation transmission method can measure a wide range of SS content (0-2000mg/L) with good repeatability

Product Details

HU-200SSOn site installation type MLSS instrument (four wire transmission)Connect the immersion MLSS sensor (SS-90) and measure MLSS in activated sludge. The use of near-infrared radiation transmission method can measure a wide range of SS content (0-2000mg/L) with good repeatability. MLSS、 Any calibration curve of clay (inorganic mud) and kaolin can be used as a standard substance for SS. If "MLSS" is used for the activated sludge treatment tank, "clay" is used for the construction sludge sedimentation treatment, and "kaolin" is used for the white sludge treatment, a concentration closer to the analytical value can be obtained.

range

Activated sludge (MLSS): 0~20000 mg/L

White inorganic powder: 0~10000 mg/L

Grey inorganic mud: 0~20000 mg/L

sturdy

Dealing with harsh conditions during on-site measurement.

Operating temperature range (transmitter): -20-55 ℃

Rated power supply voltage: AC 100~240 V ± 10% 50/60 Hz

Aluminum alloy watch box: protection level IP65

Compliant with CE marking and FCC rules, suitable for use on overseas sites.

intelligence
