The UWBT Series of Bluetooth transmitters from Omega Engineering combine the accuracy of an industrial sensor/transmitter with the convenience of a smartphone or tablet, according to the company. The transmitters measure sensor inputs including thermocouple, RTD, relative humidity and pH and transmit the data via wireless Bluetooth communication from a free UWBT app. The app can be configured in nine different languages and paired with multiple transmitters simultaneously. It also monitors and logs sensor data and displays it in digital, graph or gauge format. The UWBT logs up to 10 samples per second and logs data with date/time stamping to the handheld transmitter or directly to a mobile device or computer.
