JK9000L uses a high-brightness color 10.1-inch TFT LCD screen. A single machine can achieve up to 60 channels of data acquisition and testing. It can display the maximum, minimum and average values of temperature in real time, and an external lithium battery can supply power. It can be connected to the  computer in real time through the USB port to complete the computer real-time data collection, and the temperature and humidity curves can be directly viewed on the screen. It is suitable for the validity detection of temperature deviation, temperature uniformity, temperature passivity, relative humidity deviation, relative humidity uniformity, and relative humidity fluctuation of environmental test equipment. The temperature and humidity recorder is mainly used for the detection of equipment including muffle furnace, constant temperature and humidity drying box, constant temperature and humidity box (room), high and low temperature humidity test box, incubator, cold storage, box resistance furnace and other equipment.
