Instruction Manual for EW- T205
Firstly, thanks for you using our instruments. Combined with
extensive refrigerating techniques, operated simply,control-
led temperature accurately, and with strong interference
resisting ability, the product is a fully-automatic intelligent
control system applicable for various refrigerating and
warming equipment. The product is ultra-thin, waterproof,
high-pressure, external, more reliable and safer.Our sensors
are processed and encapsulated precisely, moistureproof,
with more stable and reliable performance.
