Here is a description of Shimadzu Moisture Analyzers, focusing primarily on their popular MOC63u model, which is widely used in laboratories and production facilities for quality control.
Shimadzu moisture analyzers determine the moisture and solid content of samples by heating them and measuring the changes in mass due to evaporation. They are highly versatile and can measure various sample types, including solids, powders, pellets, pastes, and liquids.
Key Features of the Shimadzu MOC63u
- Advanced Heating Technology: It utilizes a high-output, long-life halogen heater that provides rapid and uniform heating. The temperature can be precisely controlled between 50°C and 200°C.
- UniBloc Weighing Sensor: The internal precision balance is built with Shimadzu's UniBloc technology, which ensures excellent stability, responsiveness, and a long operational life, even with repeated temperature changes.
- Spacious Sample Pan: It features a large 95 mm diameter sample pan. This allows samples to be spread thinly and evenly, which results in faster drying times and more precise measurements.
- High Precision: The MOC63u has a maximum capacity of 60g with a readability of 0.001g, allowing for highly accurate moisture ratio calculations.
- Multiple Drying Modes: To accommodate different materials, it offers several customizable measurement modes:
- Automatic Ending Mode: Automatically stops when moisture loss drops below a specified percentage.
- Timed Ending Mode: Stops after a pre-set amount of time.
- Rapid Drying Mode: Dries at the highest temperature first, then drops to a specified temperature to save time.
- Slow Drying Mode: Gently heats samples that might solidify on the surface or degrade under high heat.
- Step Drying Mode: Allows step-by-step changes in drying conditions, which is ideal for samples with high water content.
- Data Management: It can store up to 10 sets of measurement conditions and 100 data items. A built-in USB port comes standard for easy data transfer to a PC.
- User-Friendly Design: Includes a wide observation window to monitor the sample during the drying process, an illuminated LCD for clear visibility, and simple controls.
(Note: Shimadzu also offers higher-capacity models like the MOC-120H, which features a 120g capacity, a larger 130mm pan, and a mid-wave infrared quartz heater.)
