Baoji Pest Control Technology Co., Ltd. signed a long-term cooperation strategic agreement with Shandong Huazhou Pharmaceutical Equipment Co., Ltd. Our DPI series pressure, liquid level, temperature, flow rate, PH, conductivity on-line instrumentation is praised by Shandong Huazhou Pharmaceutical Equipment Co., Ltd. for its stable performance, novel product design and advanced functions. Before Donghua Weekly, some imported brand pressure, liquid level, temperature, flow rate, PH and conductivity field instruments were used, which could not meet their technical needs and often damaged, and had a negative impact on them. After many technical exchanges between our company and Shandong Huazhou Weekly, field tests were carried out on our company's instruments. Our company's technical indicators are all equal. To meet their needs, Mr. Han Guangyong, Chairman of Shandong Huazhou Pharmaceutical Equipment Co., Ltd., and Mr. Yan Yongli of our company signed a long-term strategic cooperation framework in June 2014. Our products have been in large quantities.
