Overview
The ESH35 halogen Moisture Analyzer is a precision analytical instrument under the SDPTOP brand. It uses a 450W quartz halogen lamp as a heating source, combines a High Accuracy Weighing Sensor and a PT temperature transducer, and is used to quickly and accurately determine parameters such as moisture content and dry weight percentage in samples. The instrument has a wide range of temperature adjustment from 40 to 199 ° C and a time setting function of 1 to 99 minutes, and supports a variety of data storage and report printing.
Features
1. Support Chinese/English test report printing, and can connect to the printer through the RS232 interface.
2. Can display moisture content, dry weight percentage (Solid content) and dry weight.
The heating temperature can be adjusted within the range of + 40 ° C to 199 ° C at room temperature, and the heating time can be adjusted within 3 to 99 minutes. The heating mode, temperature, and time can be set.
450W quartz halogen lamp with a service life of up to 5000 hours.
5. Equipped with PT High Accuracy temperature transducer and temperature control protection system.
6. Provide 15 sets of parameter setting storage addresses and 5 sets of test report history storage.
7. Built-in High Accuracy Level with adjustable foot.
8. The fuselage is made of fine-cast aluminum and high-temperature resistant polymer materials (long-term temperature resistance of 250 ° C).
9. The heating compartment is designed with two layers of 304 stainless steel full mirror, which has good thermal insulation effect.
10. With a heated visual frosted glass window, it is convenient to observe the testing process.
11. The heating space is 22mm, and optional volume control heating components are available.
12. Using one-time molding anti-scalding hand test sample removal basket design.
13. Standard 50 aluminum sample plates and F2 calibrated weight.
14. Equipped with ultra-quiet micro-fan and multi-duct chill down system below 20 dB.
Principle
The instrument adopts the principle of thermogravimetry. The sample is placed on the instrument pan, and the instrument first weighs the initial weight. Subsequently, the internal quartz halogen lamp heats the sample at a set temperature and time to evaporate the water in the sample. The instrument continuously monitors and records the weight change of the sample during the heating process. By calculating the difference between the initial weight and the final weight, the moisture content and dry weight percentage of the sample are automatically obtained.
Applications
Food, chemical, pharmaceutical, agriculture, scientific research, Quality control
Steps
1. Power on the instrument, preheat and calibrate (using standard F2 calibrated weight).
2. As required, set the heating mode, target temperature (40-199 ° C), and test time (1-99 minutes) through the instrument interface.
3. Take an aluminum sample tray, place the sample to be tested, and place it smoothly on the instrument's pan.
4. Close the heating chamber cover and start the test program.
5. During the test, the sample status can be observed through the frosted glass window.
6. After the test, the instrument automatically displays and stores the results such as moisture content and dry weight percentage.
7. Use the anti-scalding hand basket to remove the sample tray.
8. You can view the historical test report through the instrument interface, or connect the printer through the RS232 interface to print the Chinese/English test report.
Notice
• The instrument should be placed on a stable working table and adjusted to a horizontal state by means of a level and adjustable feet.
• The temperature of the heating compartment and its internal components is very high after testing. Be sure to use an anti-scalding hand basket when taking out the sample to avoid burns.
• Do not exceed the capacity of the instrument 110g.
• Make sure that the heating chamber is tightly closed to ensure the accuracy of the test results.
• Regularly clean the heating chamber and pan to avoid sample residue affecting the measurement accuracy.
• The operating environment of the instrument should be kept clean and drying to avoid vibration and strong airflow interference.
