COD (Chemical Oxygen Demand), used as an indicator of water quality pollution by organic substances, can be measured simply.
■ Simplification of blank measurement By reviewing the electrode material, it is freed from multiple blank measurements, making the measurement operation faster and more stable. ■ One-touch method for sliding the electrode holder with one hand The up-and-down motion of the electrode block is done with a one-touch method, resulting in smoother operation and improved work efficiency. ■ Safer and more reliable attachment and detachment of electrodes The electrode and lead wire are integrated, improving current efficiency and contact failure issues. Additionally, attachment and detachment to and from the electrode block can be done easily, safely, and reliably. ■ Pre-alarm timer set for oxidation decomposition time In addition to an alert sound that notifies the end of oxidation decomposition, the pre-alarm timer provides an audible warning as the end approaches, so you are not bound by waiting time. ■ Strong volumetric titration method for colored samples ■ High-precision measurement using the second derivative method for endpoint detection ■ User-friendly operation panel with touch keys and interactive method
