The Plus Semi-Automated Urine Analyzer (CL-50) is a portable, semi-automated urine test strip analyzer that uses LED reflectance photometry (at 550nm, 620nm, and 720nm wavelengths) to measure up to 14 urinary parameters for rapid, objective urinalysis in clinical and point-of-care settings . Throughput is up to 120 tests per hour (continuous mode) or 60 tests per hour (single strip) with a test time of 60 seconds .
The analyzer measures 14 parameters: pH, nitrite, specific gravity, blood (hemoglobin), glucose, bilirubin, urobilinogen, ketones, leukocytes, protein, calcium, creatinine, microalbumin, and ascorbic acid, with automatic result correction eliminating interference from pH, specific gravity, and urine color .
The instrument features an LCD display, built-in thermal printer, internal memory storage for 1,000 test results, connectivity options (RS-232, PS/2, parallel port), optional barcode reader, and automatic calibration for strip sensitivity . Compact (240 x 190 x 115mm) and lightweight (1.3 kg), the CL-50 Plus is briefcase-portable, designed for use in physician office labs, mobile health units, rural health posts, pharmacy screening programs, school health initiatives, and hospital laboratory backup applications .
For the primary care physician and clinical laboratory scientist, the CL-50 Plus enables rapid UTI diagnosis (leukocyte, nitrite detection), diabetes screening (glucose, ketones), preeclampsia detection (protein, microalbumin), chronic kidney disease monitoring (microalbumin, creatinine, ACR), liver disease screening (bilirubin, urobilinogen), and hydration/acid-base assessment (pH, specific gravity). For the patient, rapid, objective urinalysis enables early detection of urinary tract infections (preventing pyelonephritis and sepsis), timely diagnosis of diabetes and preeclampsia (reducing maternal-fetal complications), and early identification of chronic kidney disease (preserving renal function), particularly in underserved communities where traditional laboratory access is limited .
