求大侠解释下温控表的英文邮件，谢谢！

我问客人的邮件 Dear Denis, Thanks for your quick reply. In order to let you use the PID Temperature Controller conveniently and rightly, I want to ask you several questions: 1）what is the input tpye of Temperature Controller ? 2) what is the control output of Temperature Controller ? 3) Our voltage range is 90-250VAC . 4) The dimension of MT900-2 is 96mm*96mm. If you feel the dimension is large , we can give you other dimesion , the other dimension is smaller than 96*96mm. So, what is your opinon? the dimension we he : 48*48, 72*72,48*96,96*48,96*96cm. Which dimension do you want? 5) Do you want to one alarm or two alarm? 客人回复我如下， Dear SIRS， 1)Input: Thermocouple K-type. 2) Output: SSR-DA 25 Solid State Relay For PID Temperature Controller, including a 600 watt heater. 3) My voltage is 220VAC. 4) Size doesn't matter. 5) I want two alarm. I'm making jewelry. This controller in any case fits me This Temperature Controller how much the temperature measures? TKS! best wishes, Denis. 客人回我的邮件的，第2点麻烦解释下。
