USB Transmitter System<\/h1>\n\n\n\n
\n
\"\"<\/figure>\n\n\n\n

Our USB sensors are divided into the following three product categories: pure temperature sensors, humidity-temperature sensors and humidity-temperature sensors plus (for measuring very high temperatures).\u00a0 The sensors measure temperature and humidity with a very high degree of precision and are operated directly via a PC’s USB port, making them particularly suitable for applications where a PC is immediately available (e.g. laboratory research\/laboratory experiments, climate chambers\/air conditioning systems, server room monitoring, greenhouses, food industry, plant engineering, and much more). In conjunction with the free SENTAX software<\/a> for data acquisition, these form a convenient measuring system with limit value monitoring and an integrated data logger.<\/p>\n<\/div>\n\n\n\n

The OT60 and OT150 measure temperature with very high precision and are operated directly from a PC’s USB port. These temperature sensors are highly reliable and accurate. Our temperature sensors are available in both A and B versions. Please refer to our data sheet for the respective sensor for accuracy information.<\/p>\n\n\n\n
