Our company makes the following commitments to customers who purchase coal testing equipment products:
The seller's on-site technical service personnel provides free guidance for the entire installation and commissioning process.
During the installation and commissioning process, if the buyer fails to comply with the provisions of the seller's technical data and the instructions of the on-site technical service personnel, and the seller's on-site technical service personnel confirms that there is a problem, the seller bears responsibility.
For the supporting materials purchased by the purchaser in relation to the contract materials, the supplier shall actively provide the technical conditions and materials that meet the requirements of the material interface.
Strengthen pre-sale, mid-sale and after-sale services, and implement "24-hour service", "advanced service", "full-process service" and "life-long service" in the entire process of product manufacturing, installation and use.
After receiving the quality problem information from the buyer, we will reply within 2 hours, and the service staff will arrive at the scene within 48 hours, so that the user is not satisfied with the quality and the service is not stopped.
We uphold the development of the coal quality analysis industry with superior products and services!
