Overview
The OBC213A is an open bath thermostatic circulator of the LABTOP brand, using a transparent polycarbonic acid ester water bath with a maximum Operating temperature of + 100 ° C and a volume of 13L. The device is room temperature controlled by chilling down the coil and external circulating water, 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 are available for external temperature control and recycling applications, suitable for sample temperature control, material testing, quality control, analysis and other fields. Using environmentally friendly natural refrigeration, with liquid level protection and over-temperature protection, according to Safety level III/FL can use flammability liquids, according to DIN 12876.

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 in the case of equipment program failure 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, users can realize 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, 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, including 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
OBC213A open bath thermostatic circulator achieves temperature control by chilling down the coil with the help of external circulating water, up to room temperature. The device adopts intelligent PID Temperature Control mode, combined with Pt100 temperature sensor for accurate temperature measurement. Optional external circulation adapter and external temperature sensor PT100 are available to expand external temperature control and circulation applications. Automatic adaptation to external loads through pressure/suction pumps ensures stable Flow rate and pressure.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
1. Connect the power supply to ensure that the Ambient Temperature is within the range of 5~ 32 ℃
2. Select the operation mode (Mode 1, Mode 2 or Mode 3) as needed
3. Set temperature parameters and calibrate with Pt100 Sensor
4. Optional external accessories, such as loop adapters or temperature sensors, for external applications
5. Start the equipment, monitor the operating status, and use the liquid level and over-temperature protection functions to ensure safety
6. Optional remote control via RS485 or RS232 interface
7. After use, turn off the device according to the specifications
Notice
• Ensure that the Ambient Temperature is within the range of 5~ 32 ° C, and the relative humidity does not exceed 80%
• Check the liquid level before use, avoid dry burning, and use the low liquid level protection function
• Set the hardware overtemperature protection temperature to prevent program failure from causing accidents
• Use only flammability bath solutions that meet Class III safety standards
Regular Pump and Sensor Maintenance to Ensure Automatic Adaptation to External Loads
• Operate the device according to the setting mode after an unexpected power failure
• When controlling remotely, ensure that the interface connection is stable
• Power supply voltage: 200~ 230VAC/50Hz
