Product introduction

Model name: a4h254-8f8t p0973jp Ethernet switch

High precision wireless communication temperature meter with low power consumption, high reliability rf radio frequency communication module, and large capacity, high performance lithium battery. With the production data acquisition terminal, the upper computer can read the real-time temperature data of the field wireless instrument through the usb interface or modbus interface. No external power supply is required, thus eliminating the need for on-site wiring of the instrument, greatly reducing labor and construction costs.
