Features :
Compliance with regulations
CR 25 COD reactor is used to digest closed micro reflux COD vial and can meet
USEPA 410. 4. It is easier and safer than traditional open macro reflux method.

Special COD program
The built-in COD programs can heat up to 150 and keep for 2-hour or 165 and keep
for 20 minutes then shut down automatically with 10-sec audio alarm.
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. 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
