The Rt Eco chloroscope is a color comparator device used to measure residual chlorine in water by matching sample color against standardized color discs. It operates using orthotolidine reagent, which reacts with free and combined chlorine to produce a yellow hue proportional to concentration. The device is housed in a compact, durable plastic casing with two glass tubes and a calibrated color wheel, designed for field use without electricity.
The comparator system follows the standard method described in Standard Methods for the Examination of Water and Wastewater (SM 4500-Cl G). Each test requires 10ml of water sample and 3-4 drops of orthotolidine reagent, with results readable in parts per million (PPM) from 0 to 2.0. The color discs are calibrated to NIST-traceable standards, and the reagent has a shelf life of 12 months when stored in a cool, dark place. This system does not detect chlorine dioxide or ozone.
Primary users include municipal water treatment plants, rural health clinics, dairy farms, and military field units across South Asia. The device is suited for low-budget, high-volume testing environments where electronic meters are impractical. Packaging includes 50 test kits per carton, each with 100 reagent drops, two glass tubes, and a color disc holder. Buyers should confirm reagent expiry dates and ensure the comparator is not exposed to direct sunlight during storage.

Before ordering, verify the reagent formulation is orthotolidine and not phenylarsine oxide or other substitutes. Confirm the expiration date on the reagent bottle and the condition of the color discs. Request a sample kit to test accuracy against a known chlorine solution. Ensure the packaging includes spare tubes and reagent caps, and check for cracks in the housing that could affect light transmission during comparison.
Confirm the Incoterms - typically FOB Chennai or CIF destination port. Lead times are usually 10 to 15 days for standard orders. Payment is commonly via T/T in advance. Buyers should request a packing list showing serial numbers for each kit and a batch-specific reagent expiry date. Ensure the commercial invoice includes the correct HS code 9027.80 for analytical instruments.
For quality control, test a random sample from each shipment using a certified chlorine solution of 1.0 ppm. Compare the reading against the color disc to verify accuracy. Inspect for broken tubes, missing caps, or faded labels. Retain a sample kit for 60 days. Request a Certificate of Conformity for each batch. Store kits in a dry, shaded location and avoid temperatures above 35°C to prevent reagent degradation.
