CT-306 Adjustable Thread Thermometer
Flexible adjustment of fixed, threaded high-efficiency temperature monitoring.


The CT-306 movable threaded temperature sensor, combining a movable thread design with a flexible sleeve, is specifically designed for industrial applications requiring frequent disassembly or repositioning, such as heaters, molds, and equipment test modules. It offers advantages such as easy installation, high applicability, and flexible customization, making it an ideal choice for efficient on-site temperature measurement.
Description
The CT-306 features a movable probe design, allowing users to easily adjust the probe insertion depth or angle, making it suitable for scenarios requiring repeated position adjustments or frequent product cleaning and testing. Both the temperature sensing element and probe length can be customized to meet various industrial application conditions.
