Overview
The OBC220EB is an open bath thermostatic circulator of the LABTOP brand. It uses a stainless steel sink with a maximum Operating temperature of 200 ° C and a volume of 20L. The device achieves room temperature control by chilling down the coil and external circulating water. It provides 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 temperature control, material testing, quality control, analysis of samples, etc., using environmentally friendly natural refrigeration, with liquid level protection and over-temperature protection functions. It meets Safety level III/FL, can use flammability liquids, and complies with DIN 12876 standard.
Features
1. Low liquid level protection to prevent dry burning
2. Hardware over-temperature protection, users can set the protection temperature through the knob, dry burning can still be avoided when the equipment program fails, 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 steam 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 equipment automatically runs after power failure, setting value can be changed), Mode 3 (power-on equipment automatically runs 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
The OBC220EB achieves temperature control by chilling down the coil with external circulating water, up to room temperature, providing a thermostatic environment for the sample to be placed directly in the water bath. The device uses intelligent PID temperature Control mode, combined with Pt100 temperature sensor and optional external temperature sensor, combined with PIDTAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology to precisely adjust and maintain temperature. The pressure/suction pump automatically adapts to the external load to ensure stable circulation.
Applications
Sample temperature control, material testing, quality control, analysis
Steps
1. Connect the power supply (200~ 230VAC/50Hz)
2. Set temperature and Miscellaneous parameters as required
3. Optional external circulation adapter or temperature sensor for external application
4. Start the device and monitor the running status
5. Turn off the power after use
Notice
• Permissible Ambient Temperature 5~ 32 ℃, relative humidity 80%
• The equipment is fixed by Benchtop to ensure stable placement
• Allow 100% continuous operation to avoid overload
• Safety level III/FL requirements when using flammability liquids
• Regularly check the liquid level and temperature protection function to prevent dry burning and overheating
