When we talked with the New Zealand customer, he was very entangled in whether to buy a coulometric method or a volumetric titrator. Then I asked him what is the water content in the sample he needs to test. He said that one sample is 70% and the other is 0.05-2%. Then I suggested that he buy the volumetric titrator, because the coulometric method (also known as the electricity method) moisture meter is only suitable for measuring trace moisture content, if the test 70% moisture content, the test results will be inaccurate.
About the payment method, the customer wants to pay with credit card, so I placed Trade Assurance Order from alibaba, then send the payment link to him. Yes, we have alibaba store, which guarantee that you can trade with us with confidence.
