Product Features
ㆍThe front of the analysis system is covered with a piece of toughened glass, which is not only beautiful,but also has good protective effect,making the LCD screen not easy to be damaged,and prolonging the service life of
ㆍ The latest touch button technology is easy to operate and has a long service life.
ㆍMenu lock switch:to prevent misoperation to change the parameters of the analysis system to affect its normal operation;
ㆍ Data storage function:recording test data regularly and querying stored data quickly;
ㆍ Alarm function:When the humidity deviates from the alarm value or runs incorrectly,the alarm value can beset arbitrarily within the full range.
