Product Description

24-hours tracing, recording and printing system[Optional]

The imported temperature recording and printing system. There are four precise temperature sensors (two sensors for some systems) inside the box and two temperature indicators outside the box, which are to display the temperature of upper and lower point, for users to supervise the temperature at each operating states in the box. The display precision--resolution is 0.1º C.
The distinguished power-off memory function can hold and store huge temperature data and information permanently.
The temperature printing has password protection function, which can prevent illegally printing of the temperature fluctuation information.
5-ways alarm system; The alarm devices with 12V power supply and220V power supply can trigger alarm simultaneously, which ensures super complementary supervision.
The remote signal alarm system (Optional)

Single channel / dual channel / multi-channel temperature data sheet management software
Communicate with PC through RS-232 interface to examine the temperature curve diagnosis diagram of one or more refrigerators and display the data sheet. The data and images can be stored, inquired and printed[Optional].

Safe control system
Keyboard lock and password protection function against missing-adjustment of the operating parameter;
Free setting of the alarm temperature range; 7 system failure alarms (high temperature alarm, low temperature alarm, sensors failure alarm, door-opening alarm, electricity failure alarm, low back-up battery alarm, low voltage alarm), code display of the failure position (some machines have all these seven alarms);
Three alarm ways (buzzer alarm, flashing alarm, remote signal alarm)
The starting delay function due to self-checking and the interval protection function between temporary stop and start can ensure the reliable operation;
Quick freezing function;
The system can record the condition of the maximum and the minimum temperature inside the box automatically without recording paper.
With the specially designed function, the system can operate under the state of sensor failure or the state of numerical disturbance safely and automatically.
The operating parameter display function can ensure that the system is under supervision by operator and with security and stability.
Special power-off memory function;
Equipped with remote alarm interface;
The distinguished operating parameter of the temperature control system can separate the operator menu from the supervisor menu, which can locate the respective responsibility of the operating parameter and the article storage.
The inbuilt lithium accumulator can keep displaying the temperature inside the box and can keep the light and sound alarm available for 72 hours after electricity failure.
