Commonly used refrigerated truck temperature recorders are generally divided into three types: paperless temperature recorders, thermometer recorders with printing functions, and wireless GPRS/GPS temperature recorders. All three temperature recorders are equipped with a temperature probe installed in the compartment of the refrigerated truck, and another part showing the temperature is installed in the cab to facilitate the real-time viewing of the current temperature inside the compartment for real-time temperature adjustment. The functions of these three types of refrigerator temperature recorders are described in detail below to facilitate the user's selection according to his own needs. Paperless refrigerated car temperature recorder The paperless temperature recorder can display the internal temperature of the refrigerator in real time, and can adjust the recording interval at any time, such as 3 minutes recording or 5 minutes recording. After driving to the target location, the temperature record can be removed. USB interface or serial port connected to the computer to download the recorded temperature data, can be directly downloaded into a word or excel file, but also through the excel file data processing into a curve for easy viewing, the recorder built-in replaceable battery, no external power supply, Small size, small power consumption, high precision, and can work continuously for more than 1-3 years. Refrigerated vehicle temperature recorder with printing function In addition to all the functions of the paperless recorder, this kind of printer with printing function adds printing function, can freely set the interval between printing, real-time measurement of the environmental temperature and humidity and paper tracking records, use of thermal paper, General to the computer city can buy. Wireless GPRS/GPS temperature recorder Wireless GPRS/GPS temperature recorder adds GSM-GPRS module and GPS function. You can insert a SIM card in the GSM-GPRS module to directly send the data to the IP address or mobile phone set on the recorder. Through the mobile network connection to the Internet, the GPRS communication traffic is minimal, and the monthly traffic is less than 20M. The refrigerated truck can automatically transmit real-time temperature data and historical data to the department requiring temperature monitoring during the running process. * High Efficiency: The unique vibratory pod design along with 50 mm thick drum provides superior compaction performance
