SP-201 Handheld Colorimetric Analyzer

The SP-201 Handheld Colorimetric Analyzer is highly suitable for water quality measurement in industries such as tap water, circulating cooling water, and sewage—specifically after the addition of oxidizing biocides like sodium hypochlorite, chlorine dioxide, and bromine-based compounds. It enables on-site rapid measurement of free chlorine, total chlorine, chlorine dioxide, and total bromine, and can also be used as a calibration instrument for online free chlorine and total chlorine analyzers.

As part of the multi-parameter and single-parameter SP-200 series detection platform, the instrument features high sensitivity, easy operation, customizable measurement methods, and battery power supply. It supports Chinese-English switching and has spawned multiple product models.

During colorimetric measurement, the SP-201 displays a dynamic "concentration-time" curve. If the displayed concentration reaches a stable value before the preset time period, the user can terminate timing in advance and read the value directly.

This unique function enables quick identification of measurements below or above a specific range and can predict long-duration measurements, solving many user pain points. For example, in total chlorine detection using the DPD method, if the displayed concentration reaches a stable value within 30 seconds, there is no need to wait for the full 3 minutes!

    Typical Applications
