One, set the budget
When we buy the equipment, we first need to have their own budget price. For low-end products we do not say, in the middle and high-end products, imported laboratory ultrapure water machine compared to domestic generally expensive, and the more high-end the difference will be greater. Therefore, if the budget is more than 300,000 + choice of imported equipment, if there is not so much budget, you can choose the domestic high-end ultra-pure water machine, relative to imported ultra-pure water machine for the domestic equipment has a higher sex ratio.
Two, look at the technical features of the equipment
Currently the laboratory ultrapure water machine are more intelligent, TOC online monitoring, EDI module, resistivity monitoring, monitoring of the various waterways, consumables life reminder, data traceability and other functions; generally in the first ultrapure water machine will be used in the TOC online monitoring (optional), and the increase of a TOC monitoring, the price difference of tens of thousands of EDI technology can greatly reduce the cost of consumables. So the fine workmanship, the more advanced technology, the more features, high research and development costs of the equipment price will naturally be higher.
Three, look at the speed of water production
Currently on the market in the laboratory ultrapure water machine water in 5-100 liters / hour, different water production, the price difference is also very large. Generally the faster the water production rate, the higher the price. Of course, users can configure the water tank to meet the centralized water demand (peak water), the size of the tank, different quality, price is different. Users can buy the right equipment according to the specific needs of their own experiments.
Four, look at the after-sales service
With the improvement of social awareness of rights and changes in consumer attitudes, the user in the purchase of laboratory ultrapure water machine, no longer focusing only on the product itself, but in the case of similar product quality and performance, more willing to choose manufacturers with quality after-sales service. Objectively speaking, quality after-sales service is a product of the brand economy, the after-sales service of well-known brand products is often better than miscellaneous products, the price will be slightly higher. On the one hand, it is based on the cost of equipment and quality, but also because the equipment plus the cost of after-sales service.
