Description
Plastic ATC Cond Probe
PRIMARY CLINICAL & DIAGNOSTIC USES
1. Conductivity and Temperature Measurement of Biological Fluids
-
Primary Use: Provides a combination conductivity electrode with a built-in automatic temperature compensation (ATC) sensor (typically a 4-ring or 4-cell graphite/platinum design) housed in a durable plastic (epoxy) body. It measures electrical conductivity (EC) and temperature simultaneously in liquids, ranging from purified water up to 350 mS for saline and high-ionic-strength solutions.
-
How it helps: For the clinical laboratory scientist and medical technologist, the 4-ring design eliminates polarization effects, allowing accurate measurement of conductivity in complex biological fluids (e.g., urine, dialysis fluid, saline). The integrated ATC sensor automatically corrects readings to a standard reference temperature (usually 25°C), eliminating calculation errors and improving the reproducibility of diagnostic testing. For the patient, accurate conductivity measurement is essential for assessing electrolyte balance (e.g., monitoring urine concentration in kidney disease) and verifying the quality of dialysis solutions.
2. Quality Control of Purified Water and Dialysis Solutions
-
Primary Use: Designed for high-accuracy measurement of resistivity/conductivity in purified water systems, water-for-injection (WFI), and hemodialysis solutions, with temperature compensation essential for USP compliance.
-
How it helps: For the healthcare facility water quality manager and dialysis technician, the epoxy body provides high chemical resistance, ensuring reliable conductivity measurement in aggressive media and compatibility with Clean-In-Place (CIP) protocols. For the patient, continuous monitoring of dialysis water conductivity prevents patient exposure to improper electrolyte concentrations or microbial contaminants in renal replacement therapy.
