I. Main technical features
1. It equips a specially designed heating bath.The gas circuit is designed reasonably and the effect of
evaporation is good.
2. The material of working bench is stainless steel. It has 3 sample wells. A pressure gauge shows the
flow rate when steam vaporizing medium is used. A ball float type flowmeter shows the flow rate
when air vaporizing medium is used. It can determine 3 samples at a time.
3. The instrument is desktop structure. Simple design and easy to operate.
