Usage:
The low-temperature circulation trough is high-accuracy thermostat which takes refrigeration and heat by itself. It can be carried on the thermostatical test in the machine water trough and it is suitable for the fields, such as petroleum, chemical industry, medicine, life sciences, measuring, light work and scientific research,etc.

Structure characteristic:
1) Circulation trough utilizes the water in the case,which is heated or refrigerated by the electricity, rising or reducing the temperature in the trough indirectly. Rising or reducing change of temperature is slower than the other direct type,then it can play a better thermostatical role. Circulate pump make water circulation flow, homogeneity kind to so as to ensure temperature inwards at the same time.
2) Interior gallbladder and case body adopt capillary to be high-efficient to gather ammonia fat foam material insulating against heat while being adiabatic,which is better heat insulation performance.
3) The low-temperature circulation trough furnishes with the appearance of intelligent high accuracy and control the temperature, adopting the microcomputer to control, and owns dealing with and timing function.It can coordinate case body temperature degree and instrument showing temperature, has guaranteed the precision of controlling the temperature automatically.
