HI-98197 Professional Waterproof Meter for Ultrapure Water
HI-98197 Professional Waterproof Meter for Ultrapure Water
The HI-98197 Professional Waterproof Meter for Ultrapure Water, supplied by GAPS Water Treatment, is engineered to meet the highest standards of precision and durability for ultrapure water analysis. With the capability to perform all three stages of USP <645> conductivity testing for water for injection, this meter is an essential tool for water professionals working in power generation, pharmaceutical, semiconductor, and other high-purity industries.
Designed for High Purity Water Applications
The HI-98197 is specifically optimized for challenging ultrapure water environments where accuracy is paramount. Its high-resolution measurements detect even the slightest changes in conductivity and resistivity, offering fast, stable readings critical for monitoring systems like mixed bed resins and high-efficiency purification equipment.
A key feature is the HI-763123 four-ring platinum conductivity probe with a threaded connection, which fits securely into the HI-605453 stainless steel flow cell. This setup ensures continuous, bubble-free sample flow and accurate results by preventing contamination from carbon dioxide and air exposure.
