The main function of the Fischer Oil Moisture Meter is to accurately measure the water content in oil using coulometric titration.
The HM401 is ideal for professionals in various industries including petrochemicals, lubricants, manufacturing, and quality control.
Coulometric titration involves generating a chemical reaction that quantifies the amount of water in a sample by measuring the charge required to react with the water present.
The HM401 moisture meter has a measurement scope of 0 µg to 200 mg of water content in oil.
Yes, the HM401 is designed to be portable, featuring a small battery power supply for on-the-go usage.
The HM401 features a color LCD touch screen that provides an intuitive user interface.
The accuracy is ±3 µg for measurements between 10 µg and 1000 µg, and for measurements greater than 1 mg, the accuracy is within 0.3%.
Yes, the HM401 includes a miniature thermal printer that records measurement data along with time stamps for easy retrieval.
The HM401 requires a power supply of 220V ±10% at 50Hz and consumes less than 40W.
The operating temperature range is between 5°C and 40°C.
The HM401 is designed to be user-friendly, featuring a color touch screen and full digital keyboard for easy operation.
The meter utilizes a new software compensation correction algorithm to enhance measurement accuracy.
The Fischer Oil Moisture Meter weighs approximately 5.5 kg.
Yes, the HM401 can operate in environments with humidity levels up to 85%.
