Which type of blood analyzer to choose for temperature measurement? ​

Tongzida Technology PT1000 precise temperature control ± 0.03 ℃, suitable for medical testing needs

In medical testing, the temperature accuracy of blood analyzers directly affects the accuracy of detection results, and traditional sensors often face problems such as accuracy drift and weak anti-interference. As the only domestic enterprise to mass produce PT1000, Tongzida's medical PT1000 temperature sensor is specially customized for in vitro diagnostic equipment, becoming the core temperature measurement solution for blood analyzers.

H2: Core requirements for temperature sensors in medical testing (why is PT1000 the preferred choice?)? ）​

Blood analyzers, biochemical detectors, and other equipment need to be incubated in a constant temperature environment of 0-50 ℃. The sensors are required to have measurement accuracy within ± 0.1 ℃, long-term stability (1000h drift ≤ 0.04%), and electromagnetic interference resistance (suitable for complex laboratory environments). Compared to PT100, the initial resistance of PT1000 temperature sensor for medical use is 1000 Ω, and the influence of wire resistance can be ignored. The long-distance transmission error is smaller, perfectly matching the strict requirements of medical equipment. ​

Precision drift problem: Using 99.999% high-purity platinum material and wet etching process, the PT1000 temperature sensor for medical use has an accuracy of ± (0.03+0.0005 | t |), far exceeding the industry standard of ± 0.1 ℃, ensuring that the detection data has no deviation; ​

Disinfection environment tolerance: Supports 121 ℃ high-pressure steam sterilization, IP68 protection level, uses medical grade materials for insulation layer, and maintains insulation impedance>100M Ω after repeated disinfection

Low power adaptation: The working current is only 0.01-0.03mA, with a self heating coefficient of 0.4 ℃/mW, to avoid sensor heating affecting sample temperature and extend device life. ​

H2: Feedback from Medical Customers: Transition from Misdiagnosis Risk to Zero Malfunctions

A certain tertiary hospital once used ordinary sensors, but due to accuracy drift, there was a 3% deviation in the detection results. After replacing the PT1000 temperature sensor used by Tongzida Medical, it operated without any faults for 6 consecutive months, and the consistency of the detection data improved to 99.9%. As the person in charge of equipment procurement said, "The stability of sensors directly reduces the risk of medical disputes, which is the core reason why we chose Tongzida
