Recommendation for Incubator

For incubator, we recommend using our “universal controller" that is faster.  For the temperature sensor, K type thermocouple is not accurate enough for incubator application. You need a RTD sensor for better accuracy. You also need a solid state relay (SSR) to interface the heater. This is because incubator normally runs more than 20 days. Mechanical relay is not reliable enough for the job. If it fails in the middle of the process, the loss is too large compared with a $15 SSR.

Here is the list of products that is the minimum for a reliable and working system.
1) Controller.
SYL-1512A
If you want the set temperature also displayed, use this one.
SYL-2362
2) Temperature Sensor
PT100S
Some people like to use the smaller sensor for fast response time. This one can be used.
PT100MN
3) Solid state relay
25A SSR

Another option for you is to use a plug and play controller.
