Overview
The LABTOP OBC213EA open bath thermostatic circulator is a device using a transparent polycarbonic acid ester water bath with a maximum Operating temperature of + 100 ° C and a volume of 13L. The device is controlled at room temperature by means of an external circulating water through a chill down coil, 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 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.
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 still over-temperature protection 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 achieve multi-stage program control, such as regular heating, cooling, thermostatic, slope and each period of time, the longest time 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 available, and accidental power failure can be automatically restored
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 device achieves precise temperature control through intelligent PID control technology and Pt100 temperature sensor, combined with chilled down coil and external circulating water system, to adjust the temperature to room temperature range. Optional external temperature sensor and circulating adapter are available to expand external temperature control and cycling applications to ensure sample stability testing in thermostatic environments.
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, optional multi-stage program control
4. Start the device and monitor the running status
5. Optional External Sensors or Accessories for Extended Application
6. Turn off the equipment after use, clean and maintain it
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 to avoid dry burning
• Set the hardware overtemperature protection temperature to prevent equipment damage when the program fails
• When optional flammability bath, it must meet the Safety level III standard
Regularly calibrate temperature sensor to ensure accuracy
• Avoid use in an unstable power environment, the device supports automatic recovery from accidental power failure
• When external control functions are optional, correctly connect the interface and signal lines
• Keep equipment clean to prevent liquid leakage
