temp data logger wireless

That depends on the radio and the surrounding metal. A standard Bluetooth unit usually holds a connection up to about 30 metres indoors if there are no thick walls. LoRa‑based loggers can go much farther—often 500 metres or more in open space, and still reliable through a few concrete walls. If the signal path has heavy shelving, a repeater or gateway helps, and many installations use a mesh of loggers that relay data.

All Kingmach loggers have onboard memory, so they keep recording at the set interval even without a live connection. When the link comes back, the stored data is automatically offloaded to the server or phone app. The memory size varies by model, but it’s typically enough for several days of readings at one‑minute intervals. Some units also have a local display that shows current values during an outage.

Yes, as long as the connector and type match. The standard input accepts mini‑plug thermocouples types K, J, T, and E, and there are also models with terminal blocks for bare‑wire RTDs. The logger automatically detects the sensor type on power‑up, so you don’t need to set anything in software. If you need a non‑standard curve, Kingmach can pre‑load a custom calibration table at the factory.

Most setups use the web dashboard or a local PC application to export CSV files that can be imported anywhere. For direct machine‑to‑machine integration, some models support Modbus TCP or MQTT, which lets SCADA or building management systems poll real‑time values. The protocol is documented, so your IT team can handle the integration without extra licensing.

Battery life varies with transmission power and sleep mode design, but a typical unit set to report every 10 minutes over Bluetooth will run about 12 to 18 months on a pair of AA lithium cells. Models that use sub‑GHz radios for long range tend to last 2 years or more with the same interval. All units give a low‑battery warning through the software well before the cells die, so you have time to swap them during a routine check.
