The RD125 Thermoreactor is a 24 position heating block for reacting Lovibond® Vario tube test vials before the measurement in a photometer. Capable of heating at 100, 120 and 150°C, and with variable time settings for 30, 60 and 120 minutes, the RD125 photometer can be used for the following methods
COD
TOC
Total Chromium
Total Nitrogen
Total Phosphate
After the desired heating period, the unit has an alarm function and will automatically cool down. The unit can also be set for continuous heating for measurement throughout the day.
