Temperature and Humidity Monitor with WiFi Function Required for Medical Cold Storages

According to the relevant regulations of the "Good Manufacturing Practice for Pharmaceuticals" (GMP) and the "Good Supply Practice for Pharmaceuticals" (GSP), drugs that are prone to deterioration in high-temperature environments must be stored in a low-temperature environment of 8°C to 20°C to ensure their stability. Research shows that for every 10°C increase in ambient temperature, the chemical reaction rates of various components in drugs will accelerate by 3 to 4 times. At the same time, both strong light and high temperature will significantly increase the risk of drug deterioration.

The following are the temperature standards for various medical cold storages:

Pharmaceutical cool storage: The temperature range is 8°C - 20°C, mainly used for the storage of conventional drugs; the relative humidity requirement is 45% - 75%.

Vaccine cold storage: The temperature range is 0°C - 8°C, suitable for the storage of vaccines and some pharmaceutical preparations.

Blood cold storage: The temperature range is -5°C - 1°C, which can be used for the storage of blood and some biological products.

Plasma cold storage: The temperature range is -20°C - -30°C, suitable for the storage of plasma, biological materials and some vaccines.

According to the requirements of the national "Good Supply Practice for Pharmaceuticals", any enterprise engaged in the operation of refrigerated and frozen drugs must be equipped with professional medical cold storage equipment with functions of automatic temperature monitoring, display, recording, regulation and alarm to ensure the quality and safety of drugs during storage.

The editor recommends installing the FT-WSD6 type Temperature And Humidity Monitor, an instrument with ultra-high and low temperature functions and Wi-Fi capabilities specially designed for hospital cold storages.

It is equipped with an LCD screen that can clearly display temperature and humidity data, device power and the current network connection status in real time, allowing users to have a clear view of the device status.

This recorder uses Wi-Fi wireless transmission technology, which can easily connect to the network and upload data through the on-site network. It can also be optionally equipped with a built-in battery for power supply, which is convenient and flexible.

Its core temperature and humidity measurement unit adopts high-quality products imported from Switzerland. The probe can be extended, and the longest probe wire can reach 30 meters to ensure accurate measurement in different environments.

In terms of data transmission, it uploads through Wi-Fi. It not only supports communication within the local area network but also can achieve wide area network communication across gateways. It also supports secondary development to meet the customized needs of different users and supports dynamic domain name system (DNS). The device parameters are configured via 485, which is simple and convenient to operate.

The temperature and humidity collection frequency is 2S/time, and the data upload frequency can be flexibly set between 1S - 10000S/time. The default data upload time is 20S/time. It also has a built-in alarm function, allowing the setting of upper and lower alarm limits and the hysteresis value. It has 2 normally open contacts and can be arbitrarily associated with alarm events for output (optional). It has a built-in buzzer and can also extend an audible and visual alarm (optional) to timely notify relevant personnel when the temperature and humidity are abnormal.

This recorder can be connected to a free local monitoring software platform, an environmental monitoring cloud platform (www.0531yun.cn or iot.0531yun.cn) and a YY version cloud platform (yy.0531yun.cn), which is convenient for data storage and remote viewing. The internal storage record cycle can be set from 1 minute to 24 hours, and the record capacity is as high as 65,000 groups, which can well meet the long-term recording and management requirements of temperature and humidity data in hospital cold storages.
