1242 12. Environmental-, soil-, water-, food analysis Sample analysis/Turbidity GENERAL CATALOGUE EDITION 20 E & OE. Turbidity meter AL250T-IR The compact Aqualytic ® infrared turbidity meter AL250T-IR is designed to allow fast, precise on-site testing. The unit measures the scattered light at an angle of 90°, as stipulated in EN ISO 7027. The wide measuring range from 0.01 to 1100 TE/F = NTU = FNU permits use of the unit for various media, ranging from drinking water to waste water. As infrared light is used for measurement, the unit can be used to test both coloured and colourless liquids. The standards required for calibration of the unit are also supplied. A second adjustment mode allows alternative adjustment with user-defined turbidity standards. - measuring ranges from 0.01 to 1100NTU (autorange) - measurement with infrared light at an angle of 90° - measurement of coloured liquids - easy operation - 600 tests between battery charges Scope of supply: AL250T-IR turbidity meter as described above, complete with 4 turbidity standards <0.1, 20, 200 and 800NTU, battery and test vial, in case. 1 AQUALYTIC Specifications Measurement cycle: approx. 9 seconds Display/Function: LCD Measuring range: 0.01 to 1100NTU (autorange) Resolution: 0.01 to 9.99NTU = 0.01NTU 10.0 to 99.9NTU = 0.1NTU 100 to 1100NTU = 1NTU ±2.5 % of measuring value or ±0.01 NTU (0 to 500 NTU) ±5 % (500 to 1100NTU) ABS Dimensions (L x W x H): 190 x 110 x 55 mm Weight (Basis unit): approx. 0.4kg Temperature: 0 to 40 °C Humidity (rel.): 30 to 90 % R.H.
