Temperature Data Logger 

DL-30/DL-1/DL-32 is a series of Temperature Data Logger with high performance versus lower price ratio, which specializes in such features as simple operation, reliable capability, low power consumption, data reservation after electricity breaking and upstanding water-proof design. The LCD can display working status and temperature values. Besides, the Data Processing (DP) software has friendly interface and can be easily used.

The Data logger can be widely used in food, medicine, refrigeration chain transportation and the walks of life, which are accordant with HACCP. It also can be applied to the locals such as labs where need temperature supervision.

Main Functions:

DL-30/DL-1/DL-32 take on the function of user information setting: include user information, stand number, upper and lower limit alarming parameters, working status indication; single button operation, status indication light can indicate each working status, start recording, select to stop recording; in comply with HACCP requirements; fixed ways of temperature sensor: the Internal and the External. (external as default). Furthermore, it can set recording interval, upper and lower

Technical parameters:
