Our clean workshop was accepted by Hangzhou Hangkang Sanitary Testing Technology Co., Ltd., and their service was very professional. There are many tests here, such as air cleanliness, planktonic bacteria, settling bacteria, static pressure difference, fresh air volume, noise, relative humidity, temperature, illumination and air exchange times. It is necessary to pass the self-inspection first, and then entrust a third-party testing organization with the qualification of cleaning testing. According to the cleanliness requirements of customers, select the corresponding sampling points for the room area. The inspection fee is charged according to the inspection content and sampling points.
