1, WSS series bimetallic thermometer in custody, installation, use and transport process, should try to avoid collision protection tube, do not make sure. When installing, it is strictly prohibited to twist the instrument case.

2, the instrument should be in -30 DEG C to 80 DEG C ambient temperature normal work.

3, the temperature of the instrument often work best in the range of 1/2 ~ 3/4.

4, double metal thermometer protective tube immersed in the measured medium length must be greater than the length of the temperature sensing element, the general immersion length is greater than 100mm, 0-50 centigrade range of immersion length is greater than 150mm, in order to ensure the accuracy of the measurement.

5, all kinds of bimetal thermometer should not be used to measure the temperature of the opening of the medium inside the container, the temperature of the thermometer should not be used in the work of the larger vibration of the control loop.

6, bimetal thermometer in the custody, use, installation and transportation, should avoid collision protection tube, do not make the protective tube bending deformation and the table when the wrench.

7, the thermometer should be regularly tested in normal use. Generally suitable every six months. The electric contact thermometer is not allowed to work under strong vibration, so as not to affect the reliability of the contact.
