Description
10ml sample bottle
Small volume ensures smaller dead volume and background moisture value. Short time required to dry the sample bottle, effectively improving test efficiency.
Hollow needle injection and gas delivery pipeline with heating function
Ensure that water vapor will not condense into water in the delivery pipeline, improving the accuracy and repeatability of the instrument.
Maximum temperature 300℃
Can meet the measurement needs of most products. Air flow rate: 0-100ml, suitable for products with various moisture release rates.
Two bottles of molecular sieve: can effectively adsorb moisture in high-purity nitrogen and reduce the impact of moisture in high-purity nitrogen on the test.
The software system can detect moisture in the environment in real time, accurately deduct drift, and reduce the impact of the environment. The real-time dynamic impedance method is used to determine the test endpoint, and the measurement results are more accurate.
Built-in thermal printer, the test results will be automatically printed after the test is completed. After the test is completed, the instrument will automatically store the test data, and can store up to 500 data. There is an RS232 interface, which can be connected to a computer to transmit data.
