Scalable Heating for Professional Research
Does your laboratory need pure, stable heat without the need for stirring? If so, the Xin Tester digital heating mantle is the perfect choice. Specifically, this DXY series delivers exceptional reliability for modern scientific research. Historically, labs bought entirely new machines for different flask sizes. However, we utilize an advanced modular design.
Advanced Modular System
Therefore, your initial investment can grow seamlessly with your laboratory experiments. This system is built entirely around modularity. Specifically, you can purchase a DXY control base (SA, MA, LA). Afterward, you simply attach various DRT heating jackets. Consequently, you support everything from 100ml to 5000ml flasks easily.
Safety and Precision
Safety is always our top priority. Therefore, high-purity glass fibers tightly wrap your glass vessels. This hemispherical design maximizes the heating contact surface. As a result, it provides a highly efficient, flameless heat source. Sensitive biological samples require strict thermostatic conditions. Fortunately, our advanced PID interface accurately tracks temperatures up to 380°C. Furthermore, the dual LED screen clearly displays both current and target temperatures simultaneously.
Every single base unit is heavily engineered for ultimate longevity. Specifically, the thick outer housing is treated with electrostatic spray-painting. Thus, the machine easily resists accidental chemical splashes and intense laboratory corrosion. Ultimately, having precise heat control prevents sample destruction. This powerful digital heating mantle is highly favored in universities, pharmaceutical plants, and environmental testing facilities. For precise calibration standards, refer to NIST Calibration Services. Please explore our complete catalog of Laboratory Heating Equipment today.

Product guides and documents
UT320D User Manual (PDF)FAQs
Q1: What is the main difference between the UT320D and UT320A models?
A: The UT320D is a dual-channel thermometer, meaning it can connect to two thermocouple probes simultaneously to compare temperatures (T1-T2). The UT320A is a single-channel model that connects to one probe at a time. Both share the same precision and wide temperature range.
Q2: Can this thermocouple thermometer measure the temperature of liquids and gases?
A: Yes. Unlike infrared thermometers that only measure surface temperatures, this contact thermometer utilizes K/J type probes that can be immersed safely to accurately measure the internal temperature of liquids, gases, and irregular objects.
Q3: How fast does the screen update the temperature reading?
A: The device features a rapid sampling rate of 4 times per second. This allows for highly responsive real-time temperature tracking, which is essential for dynamic environments like HVAC maintenance or industrial testing.
Q4: Will the thermometer save my settings when powered off?
A: Yes, the device has an intelligent memory function. Your selections for Auto Power-Off mode, K/J thermocouple type, and °C/°F temperature units are automatically saved upon shutdown, ensuring a hassle-free startup for your next use.
