COD Reactor Product Features :
◆ Compliance with regulations
CR 25 COD reactor is used to digest closed micro reflux COD vial according to ST-COD method (ISO 15705:2002) and can meet USEPA 410.4. It is easier and safer than traditional open reflux titrimetric method.
◆ Special COD program
Press start button, the reactor heats up to set temperature and countdown automatically.
Stored program:
(1) COD: 150℃, 120 min (Standard mode)
(2) COD2: 165℃, 20 min (Preheated mode)
◆ 2 additional user programs
Temperature range setting 30 ~ 200℃ and timer from 1 ~ 999 min. Built-in 2 additional heating program settings available for users to store and execute as needed.
◆ Auto shut off and audio alarm
CR 25 can stop heating then shut off automatically with audio alarm when every program is completed.
◆ Anti-heat PTFE plate
Anti-heat PTFE plate on the surface of heating block can prevent burns from the block.
◆ Thermal protection device
The reactor will auto shutoff when block temperature is over 220 °C.
