How to break through the pain points of vaccine cold chain temperature measurement? Tongzida ultra-low temperature PT1000 stable monitoring -200 ℃

In the cold chain transportation of vaccines and biological samples, temperature fluctuations exceeding ± 0.5 ℃ may lead to drug failure. Traditional sensors are prone to problems such as decreased insulation impedance and delayed response in environments below -80 ℃. The Tongzida Ultra Low Temperature Medical PT1000 sensor is specially developed for cold chain scenarios, with precise temperature measurement throughout the entire process from -200 ℃ ultra-low temperature storage to room temperature transportation, becoming a safety guarantee for medical cold chain.

H2: Extreme requirements for temperature sensors in medical cold chain

The storage and transportation of biological samples, vaccines, and other materials should cover temperatures ranging from -200 ℃ (liquid nitrogen storage) to+25 ℃ (normal temperature transportation). Sensors are required to have wide temperature adaptability, fast response (≤ 0.5s), moisture and vibration resistance (suitable for logistics environment), and accurate data transmission. The ultra-low temperature medical PT1000 sensor, with its initial resistance advantage of 1000 Ω, has far superior anti-interference ability compared to PT100, and can achieve long-distance transmission without compensating wires.

Ultra low temperature stability: Using silver palladium (AP) leads and vacuum packaging technology, the ultra-low temperature medical PT1000 sensor has an insulation impedance>100M Ω at -200 ℃ and a resistance drift of ≤ 0.04% after 1000h, far exceeding industry standards;

Quick response capability: With a thermal response time as low as 0.5s, real-time temperature fluctuations are captured to avoid drug loss caused by cold chain breakage;

Endurance to harsh environments: Anti vibration acceleration ≥ 40g, anti impact ≥ 100g, suitable for bumpy scenarios during cold chain vehicle transportation, with a protection level of IP67.

H2: Typical application case: Temperature measurement upgrade for vaccine cold chain logistics

A biopharmaceutical enterprise once caused a batch of COVID-19 vaccines to be scrapped due to the failure of its sensor at low temperature, resulting in a loss of more than one million yuan. After replacing the Tongzida ultra-low temperature medical PT1000 sensor, zero loss of vaccine transportation can be achieved through full temperature monitoring (accuracy ± 0.05 ℃). The stability of sensors directly determines the safety of the cold chain, and Tongzida's products give us complete peace of mind, "said the logistics manager of the enterprise
