Precautions for the use of micro-moisture tester
The water content of food affects the flavour of food, mould, at the same time, dry food and moisture absorption will occur after many changes in physical properties, such as bread and biscuits hardening is not only water loss and drying, but also due to changes in moisture caused by changes in the structure of the starch results in changes, in addition, in the processing of meat, such as sausages, the taste of the situation with the absorption of water, water retention is very close to the relationship between the situation, therefore, the water content of food has a very important relationship to the freshness of food, hard and soft, liquidity, taste, preservation, processing and many other aspects. So, the water content of food on the freshness of food, hard and soft, fluidity, flavour, preservation, processing and many other aspects have a very important relationship. The following look at the use of trace moisture tester precautions:
First of all, in the use of micro-moisture tester must be connected to the time part of the fast, otherwise it will be easy to reagent leakage events, which will lead to the end of the titration will be delayed, which will have a direct impact on the results of the entire experiment. There is also in the sampling time must be as short as possible to shorten the opening time of the reaction cell, and the stirring speed in the reaction cell should be fast and accurate. Only in this way can we reach the end point at a fast speed, so as not to affect the measurement results of the whole experiment.
Secondly, the trace moisture detector in the titration speed must be fast, so that the titration speed faster, in order to make it at the end of the reaction speed slower, which can greatly improve the accuracy of measurement, so in the process of measurement should be first fast and then slow.
The last thing to say is that after the test is completed, the relevant vessels must be cleaned, and the test things can not be arbitrarily thrown aside. Online moisture meter can continuously detect the moisture of the measured material in operation, and is equipped with the measured material moisture pre-set alarm system, when the measured material moisture reaches or exceeds the pre-set moisture sound and light alarm. Suitable for all kinds of factories in the production process in the continuous determination of moisture, can output 0-5V, 4-20mA measurement signal or RS485 interface to connect to the computer.
