Supply DATA TRACE wireless temperature (humidity, pressure) verification system, wireless temperature, pressure and humidity recorder

¥ Electricity Model: DATA TRACE wireless temperature verifier workstation Updated on: June 3, 2024 Product Catalog

Product advantages of datatrace wireless temperature recorder system 1. Small size, portable and practical datatrace is the smallest wireless temperature recorder in the world at present. Small size is suitable for load control manufacturing process, which requires accurate monitors, especially when one container needs to be placed in another during pharmaceutical and food processing. The datatrace temperature, pressure and humidity data recorder is small in size, even one circle smaller than the ordinary one yuan coin. It can be easily put into the mouth of the mineral water bottle, and can easily meet various harsh testing environments. 2. The datatrace temperature, pressure and humidity data recorder uses ordinary button batteries, which can be easily replaced by turning off the tracer base. Most batteries used in traditional temperature detection equipment are original special batteries, which cannot be replaced by users themselves, and the replacement time and cost are quite high. 3. Optical signal data transmission The datatrace temperature, pressure, humidity data recorder and data exchange box adopt infrared transmission mode. When reading data, just put the probe into the small hole of the base, and the probe and the base have no contact friction. This design can ensure that the probe does not reduce the sensitivity and
