Functional Overview:
The laboratory is composed of test stations and reference machine stations. The energy and water use of the entire laboratory embodies the energy-saving design concept, realizes a high degree of automation, reduces manual participation, automatic water supply, does not require manual water replenishment, and the water tank is reasonably designed to avoid water quality. Adjustment repetition and waste; can automatically adjust the heating and cooling functions according to the use of the water tank, and the room temperature and humidity control is highly efficient and energy-saving; the whiteness meter test data is directly connected to the data system; the water tank softness and hardness are automatically adjusted without manual addition of reagents .
