Overview
The LABTOP OBC358EB open bath thermostatic circulator is an economical temperature control device, available in transparent carbonic acid or stainless steel baths, with a volume of 58L and a maximum Operating temperature of 100 ° C. Room temperature control is achieved by chilling down the coil and external circulating water, supporting the sample to be placed directly in the tank for thermostatic testing, optional external circulation adapter and PT100 Sensor for external temperature control and recycling applications. Suitable for sample temperature control, material testing, quality control and chemical analysis, the use of environmentally friendly natural refrigerant, with liquid level protection and over-temperature protection functions, in accordance with DIN 12876 standard Safety level III, allowing the use of flammability liquids.
Features
1. Low liquid level protection to prevent dry burning
2. Hardware over-temperature protection, the user can set the protection temperature with the knob, and it can still be protected when the equipment program fails. It meets the DIN12876 standard level III and can use flammability bath liquid.
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 time settings, the maximum time of each period is 999 hours
5. Equipped with external temperature sensor interface, optional movable external temperature sensor, with PIDTAC control, Cascade cascade control and bath temperature difference lock control technology, precise control of 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 and 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. Optional set of 5V external input switch signals for external smart devices to control the start and stop of the instrument
16. Optional 0-10V or 4-20mA analog signal input for external smart devices to control instrument start and stop
Principle
The device achieves precise temperature regulation through intelligent PID control technology and Pt100 temperature sensor, combined with chill down coil and external circulating water system, to control the temperature within the set range. The pressure/suction pump automatically adapts to the external load to ensure stable Flow rate and pressure, optional external Sensor and cascade control technology to achieve precise temperature management of external materials in the bath.
Applications
Sample temperature control, material testing, quality control, chemical analysis
Steps
1. Connect the power supply to ensure that the Ambient Temperature is 5~ 32 ° C and the relative humidity does not exceed 80%
2. Select the operation mode (Mode 1, Mode 2 or Mode 3) as needed
3. Set temperature parameters, optional single point, two point or multi point calibrated
4. Start the equipment, monitor temperature fluctuations and pump operation status
5. Optional External Sensors or Accessories for Extended Application
6. Turn off the equipment after use, clean and maintain it
Notice
• Make sure the liquid level is normal and avoid dry burning
• Set the hardware overtemperature protection temperature to prevent equipment failure
• Safety standards must be met when using flammability liquids
• Ambient Temperature 5~ 32 ℃, relative humidity not more than 80%
• Power supply voltage is 200~ 230VAC/50Hz to ensure matching
Check Pump and Sensor Status Regularly
• Optional accessories need to be installed and used correctly
