FAQ
Q1. What are the special advantages of the pH instruments?
A: The instrument can not only compensate the temperature of the test sample by connecting the temperature sensor, but also self-check the working temperature of the instrument in real time. When the working temperature of the instrument changes, the instrument compensates the hardware change caused by the temperature drift. Make the test results more accurate, this is a patented technology.
Q2. Does the conductivity controller operation interface support customization?
Yes, our conductivity controller operation interface can be tailored to customers' needs.
Q3.Can customer's logo be added to the controller system and cover?
Of course, we support OEM services for customers. Both the boot interface and the controller shell can be added to the customer's logo, but there is a minimum order quantity requirement.
Q4.How long is the warranty period?
The company guarantees the instrument for one year (12 months) from the date of shippment, and the consumables and wearing parts in the equipment are not covered by the warranty.
Q5. Does the conductivity controller have an ambient temperature alarm function?
Our EC controller has ambient temperature alarm function.
Q6: What is your shipping method?
A: Small orders are delivered by international express, Bulk orders are recommended to ship by sea.
