TB250 WL – Compact Lovibond® White Light Turbidity Meter

    • “White Light” source turbidity meter
    • Range from 0.01 to 1100 NTU
    • EPA turbidity measurement (standard 180.1)
    • Auto-Ranging feature
    • Regulatory monitoring, process control & field use

Description

The TB 250 WL allows easy turbidity measurement in either the field or in the laboratory. Using a “White Light” source and 90° detection, theTB 250 WL meets the specifications for EPA turbidity measurement (EPA standard 180.1). A powerefficient micro-circuit design allows the instrument to yeild 5000 tests on alkaline batteries with an estimated 7 to 10 year bulb life. Intergrated diagnosits confirm proper operation and accuracy. The instrument provides an Auto-Range feature that automatically slects the correct turbidity range for the sample

Calibration is simple with the included calibration standards. The instrument comes with all required items for testing including the TB 250 WL Turbidimeter, sample curvettes, batteries, calibration set, operators manual and carrying case.

TB210 IR – Compact Lovibond® Infrared Turbidity Meter

    • Fast, precise, on-site testing
    • Range from 0.01 to 1100 NTU
    • Coloured and colourless liquids
    • EN ISO 7027 compliant
    • ≥600 tests per battery life

Description

The compact Lovibond® infrared turbidity meter TB 210 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 makes the instrument suitable for various applications, ranging from drinking water to waste water.

As infrared is used to measurement purposes, 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

AQUA LX

The AquaLX® app, available free of charge, offers the possibility of transferring measurements to smart phones or tablets via Bluetooth®. The data management then enables analysis and export as a CSV file or graph via email. The app is available free of charge for AndroidTM and iOS®.

IRIM INFRA-RED DATA TRANSMISSION MODULE

The IRIM (Infra-red data transmission module) uses modern infra-red technology to transmit data from the MD610 to one of 3 optional interfaces. This allows the MD610 to be connected to a computer or printer. For more information on the IRIM click here.

VERIFICATION STANDARD KIT

The verification standard kit for the MD 610 is designed to assure the user of the accuracy
and the reliability of the results related to the integrated wave lengths. The shelf life of the verification standard kit is
two years from the date of production, provided that storage and use are in accordance with the instructions provided.
