Overview
The OBC206A is an open bath thermostatic circulator of the LABTOP brand. It uses a transparent polycarbonic acid ester water bath with a maximum Operating temperature of + 100 ° C and a volume of 6L. With the help of a chill down coil and external circulating water, the temperature can reach room temperature, providing an economical solution for the sample to be placed directly in the water bath for thermostatic testing. Optional external circulation adapter and external temperature sensor PT100 support external temperature control and recycling applications, suitable for sample temperature control, material testing, quality control, analysis and other fields. It uses environmentally friendly natural refrigeration with level protection and over-temperature protection, meets Safety level III/FL, can use flammability liquids, and meets DIN 12876.
Features
1. Low liquid level protection to prevent dry burning
2. Hardware over-temperature protection, the user can set the protection temperature through the knob, and can still over-temperature protection when the equipment program fails to avoid dry burning, in line with DIN12876 standard level III, flammability bath liquid can be used
3. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load
4. Optional multi-stage programmable controller, supports multi-stage program control, such as regular heating, cooling, thermostatic, slope and each period of time, each program can set the running time, up to 999 hours
5. Equipped with external temperature sensor interface, optional movable external temperature sensor, with PIDTAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, precise control of bath external material temperature
6. Pt100 temperature sensor, support single point, two point and multi point temperature calibrating
7. Liquid or vapor contact parts are made of high-performance stainless steel and high-performance plastics
8. Optional related accessories to form different internal and external applications
9. The buzzer can be set to silent or audible
10. Multiple operation modes are optional, and accidental power failure can be automatically restored: Mode 1 (power-on equipment stops after power failure, setting value can be changed), Mode 2 (power-on automatic operation after power failure, setting value can be changed), Mode 3 (power-on automatic operation after power failure, setting value cannot be changed)
11. The device serial number can be queried through the software
12. Optional intelligent control functions: a variety of interfaces (RS485, RS232), to achieve remote communication, control equipment start and stop
13. Optional normally open and normally closed 2 external contact points, can be connected to external alarms
14. Optional set of 12V switch Output signal for controlling external solenoid valve
15. An optional set of 5V external input switch signals can be used for external smart devices to control the start and stop of the instrument
16. Optional 0-10V or 4-20mA analog signal input, can be used for external smart devices to control instrument start and stop
Principle
OBC206A open bath thermostatic circulator monitors temperature with Pt100 temperature sensor through intelligent PID Control mode, combines chill down coil and external circulating water to achieve temperature regulation, up to room temperature. Optional external temperature sensor and circulation adapter to support external temperature control and circulation applications. The device adopts pressure/suction pump, pump pressure and Flow rate automatically adapt to external load, ensuring stable operation of thermostatic cycle.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
1. Connect the power supply and ensure that the Ambient Temperature is within the range of 5~ 32 ℃
2. Set temperature parameters as required, optional multi-stage program control
3. Start the equipment, monitor temperature fluctuations and operating status
4. Optional External Sensor or Circulation Adapter for External Temperature Control
5. The device supports automatic recovery from unexpected power failure, and operates according to the setting mode
6. Turn off the device and disconnect the power after use
Notice
- Ensure Ambient Temperature in the range of 5~ 32 ℃, relative humidity does not exceed 80%
- Check the liquid level before use to avoid dry burning. The equipment has a low liquid level protection function
- Set the hardware overtemperature protection temperature to prevent overheating due to program failure
- When optional external alarm and solenoid valve, correctly connect the external contact point
When controlling remotely, ensure that the interface (e.g. RS485, RS232) is connected stably
Equipment allows 100% continuous operation, but requires regular maintenance of the pump and Sensor
- Safety level III/FL must be met when using flammability liquids
- Avoid operating equipment outside the Temperature range (RT + 10~ 100 ° C)
