wireless data loggers temperature

Kingmach designs its wireless temperature data loggers to operate in a wide range of environments—from -200 °C cryogenic storage to 200 °C sterilization processes. The sensor input accepts standard Pt100 RTDs, thermocouple types J, K, T, and NTC thermistors, with a typical accuracy of ±0.2 °C for RTD and ±0.5 °C for thermocouples after calibration. Recording resolution goes down to 0.01 °C, and users can set logging intervals from 1 second to 24 hours. Each channel stores up to 100,000 timestamped readings in non-volatile memory, so data won't be lost if the battery dies. Communication-wise, the loggers can operate in a 2.4 GHz mesh network covering a building site, or use Wi-Fi and Ethernet gateways for cloud integration. For remote locations, optional LoRa or NB-IoT modules provide kilometers of range with minimal power draw. All models are compatible with Kingmach's PC software and can output CSV files for Excel, as well as feed JSON data to third-party systems via REST API. Battery life extends to two years with standard AA lithium cells, and external power or solar is possible for permanent installations. The housing is available in IP65 or IP68 versions, and ATEX-certified enclosures are an option for hazardous areas. Customization doesn't stop at the probe; Kingmach can adjust logging firmware, add custom alarm logic, and even screen-print your logo on the enclosure. Our global support team helps with network planning, commissioning, and calibration services so you're not left to figure things out alone.
