The system adopts the integrated design of graphite digestion and super constant temperature water bath, which occupies a small area and can be put into a standard fume hood for operation.

It has the function of dispelling air-cooled reflux, and the dissipation is less than 1%.

It has the function of water bath refrigeration, and can realize rapid cooling and normal experiment under high temperature conditions.

Small size: 500mm in front and back length, which can be put into a standard fume hood for operation.

Measurement accuracy: digestion and dissipation: ≤1%

Linear correlation coefficient: γ>0.9995

High efficiency: single measurement time is less than 15 seconds.

Urine iodine: it takes less than 4 hours for 120 samples to be digested and tested.

Water iodine: 60/hour in the whole process test.
