The HZWS-Y Insulating Oil Micro-Water Tester employs the Karl Fischer Coulometric titration method — the most reliable technique for measuring trace amounts of water in various substances. Incorporating advanced automatic control circuits and a 32-bit embedded microprocessor as its core, along with a mini operating system, this tester ensures reliable operation and ease of use. It delivers fast analysis speed, simple operation, high precision, and strong automation.
The tester is widely used across industries including petroleum, chemical, electric power, railway, pesticide, pharmaceutical, and environmental protection.
