A:bear earthquake double the metals thermometer is a kind of to suit to measure medium, the spot of the low temperature examination appearance, can use come direct diagraph liquefaction,air of temperature.With the comparison of the local and the same kind product:The gauge accuracy grade attains 1.0 classes, the hull adoption antisepsis material on the gauge, its hot-resistant can be up to 200 ℃s, lowest is-40 ℃s.The method type structure, double the layer seal completely the gum turn, past antisepsis, waterproof function good.Protect the tube welds to adopt the full-automatic argon gas protection tube,to sew firm,the  decay small.The mark degree the dish is an aluminum to oxidize the printing dish, surface clear style beauty.Point needle for inside adjustable type.
Two:main technique index sign
1:the usage scope:;
-50-50 ℃s;-20-80 ℃s;0-50 ℃s;0-100 ℃s;0-120 ℃s;0-150 ℃℃s;0-200 ℃s;;0-300 ℃s;0-400;0-500 ℃s is special and can make to order.

2:install tooth(movable tooth with fix the tooth all can make to order)
27 ×s 2 mms;3/4;1/2;1/4

3:the dial diameter is:100 mms, path to install a type.

Three,the usage and maintenance
1,double the metals thermometer should avoid collision pay to accept a tube in the preservation, the usage and the gearing, making to pay to accept a tube flection to transform and using the case of watch wrench absolutely not to.
2,each kind of metalses thermometers should not used for measure to open container inside lie the quality temperature, take electricity the point of contact thermometer, disallow Be vibrating severely under the work, in order to prevent influence the point of contact credibility.
3,at the pressure is big in the 1.5 MPas, should choose to use the JX series protection tube.
Four,order beard to know
1,order the beard write the model number of the clear product,measure scope,connect way with specification and put deeply,outer shell diameter,accuracy grade,pay to accept to take care of outside path etc..
2,there is special request, the beard concretely notes.
