A ATC pH Probe (3-in-1) is a combination electrochemistry sensor that integrates pH sensing, reference electrode, and automatic temperature compensation (ATC) into a single probe, designed for accurate, simultaneous measurement of pH and temperature in clinical diagnostic, pharmaceutical quality control, and research laboratories . The built-in ATC sensor automatically corrects pH measurements for temperature-dependent variations in electrode slope, ensuring accurate readings across a temperature range of 0-90°C (or 0-100°C for specialized models) .
The probe features an epoxy body for durability and chemical resistance, an Ag/AgCl reference system (gel-filled or refillable), and a glass sensing bulb with a pH range of 0-14 . Available junction types include wick (general purpose), glass fiber (low maintenance), and ceramic (high precision), allowing selection based on sample type and application requirements . Response time is rapid, with stable readings achieved within 30 seconds at 25°C .
For the clinical laboratory scientist and medical technologist, the ATC pH Probe (3-in-1) simplifies pH measurement of biological fluids including serum, plasma, urine, and cerebrospinal fluid—reducing the need for separate temperature probes and minimizing sample handling . For the clinical pathologist, accurate pH measurement supports diagnosis of metabolic acidosis, alkalosis, diabetic ketoacidosis, and renal tubular disorders. For the quality control chemist, the probe provides reliable pH measurement of calibration buffers and QC samples, ensuring that pH meters used for patient sample testing are properly calibrated and functioning within acceptable parameters .
Compatible with pH meters accepting BNC and Mini-DIN/8-pin connectors, the ATC pH Probe (3-in-1) is an essential tool for clinical chemistry laboratories, pathology departments, pharmaceutical QC labs, and research facilities requiring accurate, reproducible pH measurement for patient sample testing, quality control, and diagnostic applications.
