Specifications
SKU: DATATEST DT-300BT485 485 Communication Standard Platinum Resistance Thermometer
Brief introduction:
The sensor of the 485 communication standard platinum resistance thermometer adopts platinum resistance design technology. To ensure excellent temperature accuracy, the sensor is designed in a stainless steel probe and connected to a high-precision temperature measuring device. The sensor and measuring circuit are sealed in a stainless steel housing. This integrated design is less susceptible to external mechanical shocks compared to ordinary standard thermometers, making it more suitable for field measurement environments and providing an overall accuracy of 0.05℃.

I. Overview:
The sensor of the 485 communication standard platinum resistance thermometer adopts standard platinum resistance design technology. To ensure excellent temperature accuracy, the sensor is designed in a stainless steel probe and connected to a high-precision temperature measuring device. The sensor and measuring circuit are sealed in a stainless steel housing. This integrated design is less susceptible to external mechanical shocks compared to ordinary standard thermometers, making it more suitable for field measurement environments and providing an overall accuracy of 0.05℃.
The highly reliable design, combined with an integrated temperature probe platinum resistance sensor, provides high-precision temperature measurement. The customizable probe length (4mm diameter) offers faster temperature response and a temperature measurement range of -100℃ to +200℃ (optional -200℃ to +350℃) .
This standard thermometer features an industrial RS485 digital interface for outputting temperature values. Multiple sensors can be networked together. It has a wide power supply range of 8-30V DC and strong anti-interference capabilities, ensuring long-term stability and reliability. The housing is made of 304 stainless steel, compatible with various liquids, and meets IP66 standards for waterproofing. Higher waterproof ratings can be customized.
II. Features:
n Standard thermometer with RS485 interface (various temperature probes optional)
n Integrated temperature sensor, 0.05℃ accuracy
