Spectrophotometers are precision instruments and should be properly maintained and carefully maintained to ensure long-term use of the spectrophotometer, long-term stability and reliability, and high measurement accuracy. In the course of many years of production and application, Yuanxuan Company has obtained a set of experience in maintaining spectrophotometer under a certain environment, as follows: 1, the ambient temperature under conditions permitting, as far as possible to maintain between 15-30 degrees Celsius, so that can maintain the stability of electrical devices, not easy to aging, so that the spectrophotometer is not easy to damage, the lamp life is extended. If conditions do not allow, in the case of high temperatures, shorten the boot time, efficient use of spectrophotometer, so that the electrical components do not maintain long-term high temperature. At a low temperature, the warm-up time is longer than the warm-up time at room temperature, so that the test can be performed with the instrument stable. 2. The ambient humidity should be kept below 60% if conditions permit. This can ensure that the optical components and electrical components inside the photometer are not susceptible to moisture, corrosion, and mildew. If the conditions are not allowed, keep ventilation at high humidity and low humidity as much as possible. 3. The environment should be kept as clean as conditions permit. When cleaning the environment, the movement should not be too large. Do not raise dust. Before cleaning, use a dust cover to cover the spectrophotometer and do not allow the dust to enter the interior of the spectrophotometer. The above only describes the external environment used by the instrument for the user's reference.
