COD Test Tube Heater with 25 Vials for COD – HI839150-02
HI839150 is a robust 25 vial capacity thermo-reactor for COD determination of industrial wastewater. The reactor has two stored digestion temperature programs that support analysis methods at 150 °C and 105 °C. The HI839150 is a robust 25 vial capacity thermo-reactor for COD determination of industrial wastewater. The reactor has two stored digestion temperature programs that support analysis methods at :
– 150 °C (COD methods, Iron Total, Phosphorus Acid Hydrolyzable, Phosphorus Total methods)
– 105 °C (Chromium and Nitrogen Total methods)
• Laboratory safety shield included
– The included safety shield is highly recommended to use during vial digestion procedure to maintain a safe working environment
• Reactor block temperature continuously evaluated and displayed
• Built-in countdown timer
– A timer of up to 180 minutes is included for applications that require timed digestions. The end of the digestion time is signaled by 5 short acoustic beeps and “DONE” message is displayed. The heating is turned off and the block begins to cool off.
• Status indicator lights
– POWER (on)
– HOT (surface)
– HEATING (in progress)
• Overheating prevention
• Reference temperature probe well
– A small temperature well can accommodate a temperature probe, useful for verifying the heating block.
• Warnings and error messages
– The instrument displays warning messages when erroneous conditions appear and when values are outside the expected range such as high or low temperature, hot surface, or heating system malfunction.
