Hanna HI3875 Chlorine as Cl₂ free Range 0.0-3.5mg/L

Hanna HI3875 Chlorine as Cl₂ free Range 0.0-3.5mg/L

The Hanna HI3875 Chlorine as Cl₂ free Range 0.0-3.5mg/L  is a high-quality chemical test kit designed for the accurate measurement of free chlorine (Cl₂) in water. It uses a colorimetric method based on DPD reagents and a checker disc system, offering dependable results within a range of 0.0 to 3.5 mg/L. This kit is particularly useful for applications that require regular and reliable water quality monitoring.

Features

• Reliable and Easy-to-Use Method
  The test operates using a checker disc, allowing users to visually match the sample color to determine chlorine concentration. As a result, it delivers consistent and repeatable readings without the need for electronic instruments.

• Wide Testing Range
  It covers a measurement range from 0.0 to 3.5 mg/L, making it suitable for both low-level and moderate chlorine monitoring. Moreover, this range aligns with most regulatory guidelines for potable and recreational water.

• Enhanced Precision
  With a resolution of 0.1 mg/L, the kit offers excellent sensitivity. Therefore, users can detect even small changes in chlorine concentration.

• Complete Testing Setup
  The HI3875 includes all required components, such as cuvettes, a checker disc, and DPD reagent packets. Consequently, users can begin testing immediately after unpacking the kit.

• High Volume Testing Capacity
  Designed to perform up to 100 tests, the kit is both cost-effective and ideal for frequent water testing routines.
