HONGKE Solution] Accurate and Compliant: HONGKE ELPRO Temperature Recorder in Refrigerator Certification

Maintaining accurate temperatures is not only critical to the quality of pharmaceuticals and food, but is also a core element of many other products and industrial processes.
Therefore, it is important to make sure that the products used in refrigerators, freezers, ultra-low-temperature freezers, cryogenic containers, or incubators are not used for any other purpose.Temperature Data Loggers and SensorsBeing in good condition and calibrated is essential to the daily work of the laboratory when handling, analyzing or storing.
Monitor the temperature of refrigerators, freezers, etc. with a temperature logger that can provideReliable temperature monitoring dataup toProof of ComplianceThe

During the operation of refrigerating or freezing equipment such as refrigerators, the temperatures at various locations inside the equipment may differ, even significantly, due to the way the refrigeration operation is carried out and the way the samples are placed.
Therefore, throughTemperature Distribution VerificationThis ensures that the temperature at all points inside the device is within the specified range, safeguarding the safety and quality of stored items.

How to choose the right temperature recorder for verification?

  • Select ECORDER type: Internal sensor, external sensor, wireless recorder, recorder with display, etc.
  • Select ECORDER parametersMeasurement Accuracy, Temperature Range, Storage Capacity, Battery Life and Data Transmission Methods

According to GB/T 34399-2017 It is required that the temperature recorder should be periodicallyCalibration or Verification::

  • Measurement range 0 ℃ ~ 40 ℃, maximum tolerance ±0.5 ℃.
  • Measurement range -25 ℃ ~ 0 ℃, maximum tolerance ±1.0 ℃.

To enhance ease of use, companies often choose toHigher storage capacity,Longer battery lifeThe recorder is a recording device that is used to record the number of times that a person has been in contact with the computer.

  • Data analysis capability: Ensure that the recorder is compliant, that no data is lost, and that it produces complete data suitable for analysis.

[Hongke Case Study] ELPRO LIBERO Series Temperature Loggers—Ensuring the Safety of High-Value Biopharmaceuticals

High-value novel biopharmaceuticals have extremely stringent cold chain temperature control requirements; even the slightest temperature deviation can result in losses of tens of millions of yuan and pose compliance risks. Using the example of a major domestic pharmaceutical group’s implementation of Hongke’s ELPRO LIBERO series temperature loggers, this article provides an in-depth analysis of how the system achieves zero-incident temperature control throughout the entire process (2°C to 8°C) and dual compliance with GSP and international standards through the automatic generation of tamper-proof PDF reports, SmartStart batch configuration, and standardized SOP services.
