Fison ESR Analyzer measures erythrocyte sedimentation rate by infrared detection, with each channel tracking red blood cell sedimentation and reporting its own Westergren ESR value. The 40 analysis channels test up to 40 samples at the same time, and throughput reaches up to 80 tests/hour, so full batches are analyzed in parallel. As a sed rate machine, the analyzer automates ESR readout and returns a Westergren result for every sample in the batch.
