    FAQs

    Q1: What is a temperature data logger?
    A1: A temperature data logger is one of the types of temperature measuring instruments. With the popularization and wide application of computers, temperature data recorders have been produced. And because of its more accurate data recording, more convenient data storage, and more convenient data analysis functions, it has been widely used. Paperless temp data logger with USB interface also greatly facilitates the downloading and saving of data.

    Q2: What are the functions of temperature data loggers?
    A2: Measurement: Built-in temperature sensor or connectable external temperature sensor to measure temperature.
    Record Storage: Automatically record and store measured temperature values.
    Data transfer: transfer or download the saved measurement data to the computer through the USB interface.
    Programming: such as setting sampling rate, data transmission method and interval, selecting temperature sensor type, alarm setting, etc.
    Analysis: Perform the necessary analysis on the temperature data through the built-in software.

    Q3: What are the advantages of temperature data loggers?
    A3: The portable temperature and humidity data logger can regularly collect and record temperature and humidity parameters according to the configured time interval, and can transmit the collected and recorded data to the computer for processing and drawing charts. It is widely used in environmental protection, health and epidemic prevention, warehousing and transportation, museums, greenhouses and other fields. This recorder is powered by high precision sensors and high-energy lithium batteries. It is designed with low-power technology and requires no external power supply. It is small in size, low in power consumption, and high in precision. It can work continuously for more than three years.

    Tips: Daily Use Precautions for the WIFI Temperature and Humidity Data Logger

    • The installation location should be carefully selected. Avoid placing the device directly on metal surfaces or near heat or cold sources. A distance of 10-20 cm from the wall is recommended. In cold storage, it can be mounted mid-level on a shelf to ensure the measurement environment closely matches actual storage conditions.
    • Prioritize a stable WIFI connection: During initial configuration, install the device as close to the router as possible. For multi-area deployments, use a signal amplifier to ensure uninterrupted cloud data synchronization.
    • Data management should be timely: Set up daily automatic backups, manually mark important milestones (such as batch changes), and regularly export and archive cloud reports for quality traceability.
