Multichannel USB Temperature Logger![]()
UPTEMP USB Temperature Logger with Two Sensor Connectors and a USB Type-A to Mini-B Cable Application Idea upTEMP™ temperature loggers can be easily stacked using the connection guides included on the housing. ![]() Please Wait ![]() Click to Enlarge The connection channels guide the upper module onto the lower module, creating a stable stack. ![]() Click to Enlarge Connection channels at the corners of the upTEMP housing are included for easy stacking of modules. Features
Thorlabs' upTEMP™ Multichannel Temperature Logger is a compact, USB-powered device designed for monitoring and saving temperature data in both laboratory and factory environments. The upTEMP logger can read up to eight negative temperature coefficient (NTC) thermistors or four resistive temperature detector (RTD) sensors. The sensor output is read with ±0.5 °C accuracy at 25 °C and ±1 °C accuracy over the -10 °C to 70 °C temperature range; these values do not account for sensor accuracy. This temperature logger, designed for use with a PC, is powered using a USB and can be controlled using the included upSERIES software. Several modules can be used in parallel for applications that require more than the eight sensor connections provided by one device, making these an ideal option for OEM applications. To retain the compact footprint (86.7 mm x 52.5 mm) of a single unit while using multiple devices, the upTEMP housing has been designed with connection channels at the corners, which help create a stable assembly of devices. ![]() Click to Enlarge The main upSERIES software GUI displays temperature measurements from a data set, and it is possible to zoom into different regions of interest. Temperature values and time stamps for each data point can be read out. Sensor Compatibility Each upTEMP module ships with two push-in spring connectors to connect the temperature sensors; additional connectors can be purchased by contacting Tech Support. Please see the Pin Diagram tab for more information on the pin assignments for each sensor type. Back Panel Features A status LED indicator is included on the back panel to easily identify the operation status of the device. When the upTEMP is in measurement mode (outputting data but not saving to internal memory), the LED appears a steady green; the LED blinks yellow if the device is logging data (saving to internal memory). The LED can also appear additional colors for special states; see the device manual for more details. A start/stop logging button is included on the upTEMP temperature logger to run measurements without the upSERIES software or a PC connection. In this case, the device must have available internal memory and power supplied via the USB port; we recommend using the Thorlabs DS5 power supply with a USB type-A port. Note that the software must be used to set the measurement configurations and to view or export the data. PC Control
Front PanelThorlabs' upTEMP™ USB temperature logger features sixteen pins, which can connect up to eight negative thermal coefficient (NTC) thermistors or four resistive temperature detector (RTD) sensors using the two included sensor connectors. RTDs with two-, three-, and four-wire configurations can be used. Shown below are the pin assignments for connecting NTCs (left) or RTDs (right). Note: In the case that a two-wire RTD is used, connections should be made to the two inner pins. See the upTEMP manual for more details.

SoftwareVersion 1.0 The upSERIES software includes a GUI for control of Thorlabs' upTEMP USB Temperature Data Logger. To download, click the button below. upSERIES™ Software for the upTEMP™ USB Temperature Data LoggerThe upSERIES software package is designed for remote operation of the upTEMP temperature logger. The temperature measurements detected by negative temperature coefficient (NTC) thermistors or resistive temperature detector (RTD) sensors can be monitored, saved, and evaluated using the intuitive, easy-to-use graphical interface. Ideal for complex systems, this software can be used to measure signals from multiple upTEMP modules, and each module can handle up to eight NTC thermistors or four RTD sensors. Data can be saved to the internal memory of the upTEMP device or to the PC. The GUI features a configuration section, which allows the user to edit measurement parameters, including sensor type, temperature offset, and measurement delay. For real-time temperature monitoring, there is an option to display temperature measurements graphically in a time trace. Data analysis options, such as displaying single temperature values, are also included. Data saved to the PC will be saved as a .csv file with the following information: time and date; sensor type and number (according to list in the software); temperature scale; and calculated and displayed temperature values. ![]() Click to Enlarge The upSERIES software automatically recognizes a connected upTEMP temperature logger. The connected upTEMP device is listed in the left panel and configuration options are on the right. The center panel shows the temperature readings for each connected temperature sensor. ![]() Click to Enlarge The category, which is based on the resistance at 0 °C (labelled as PTxxx), and the calibration curve can be set for connected RTD sensors. ![]() Click to Enlarge For connected NTC thermistors, the temperature coefficents and operating temperature ranges can be set. The Thermistor Model Manager also allows new NTC thermistors to be added, and they can be configured using the Steinhart-Hart equation or beta function. ![]() Click to Enlarge Measurement parameters can be configured in the right panel of the main GUI screen. Measurement delay, which is the update rate of the measured data on the screen, can be set, as well as the data set name. Also, options for saving the data can be set in this panel. ![]() Click to Enlarge The live data can be displayed in the main GUI window. Also available are basic data analysis tools, including the capability to zoom into data sets and read the temperature for single data points. Time references for each data point can also be read out.
