    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: How can Correctly Use a Temperature and Humidity Recorder to Better Control Errors?

    To properly use a temperature and humidity recorder, hang it in a central location, away from heat sources and walls. Calibrate it before use and every 6-12 months. Wear gloves when handling it and avoid touching the probe. Allow it to sit for 30 minutes before recording. Clean the probe after exposure to high humidity. Store it in a dry place when not in use for extended periods. Keep usage records for traceability.

    A portable temperature and humidity data logger with clear reports.
    We've been using this portable temperature and humidity data logger in our dairy processing workshop for two months and are very satisfied with its performance. Its high accuracy allows for real-time monitoring of subtle changes in temperature and humidity, which is crucial for dairy production. The device is compact and lightweight, allowing for flexible placement at various workstations. Its excellent data storage capabilities allow for long-term recording of large amounts of data. We've set it to record every 15 minutes, which easily meets our daily needs. Data can be exported directly to a computer via USB and saved in a variety of formats, making it convenient for preparing quality inspection reports and conducting data analysis.
