Oil and Grease analyzer LOGA-A10

Oil and Grease analyzer LOGA-A10


Oil and Grease analyzer LOGA-A10 is a tabletop analyzer with a sample testing range of 0.12 mg/L to 840 mg/L. The unit displays and prints the sample spectra, position and wave number of the absorption peak. It features self-contained optical and electrical system with high degree integration. Testing data and spectrograms can be saved to hard disk for checking and printing anytime Sensor signal processing uses lock-in amplifier circuit improving the analyzer’s SNR and the minimum detection limit.
