USB PRECISION TEMPERATURE SENSOR The TMP125 is a USB temperature sensor based on a precision temperature chip. It can measure temperatures as low as –55 °C ◌ OEM ◌ Greenhouse ◌ Server rooms ◌ Manufacturing with a resolution of 0.5 °C. Its sensing probe has dust, moisture and splash-proof envelope. This high level of protection makes it possible to use the TMP125 in harsh environments. ◌ Pre-certification ◌ LIMS integration ◌ Humidity control ◌ Scientific research ◌ Building automation ◌ Engineering and R&D ◌ Environmental chamber INSTALLATION TIME Less than 10 minutes UNIQUE SERIAL NUMBER Each unit is assigned a unique serial number allowing for traceability and certification FREE DAQ SOFTWARE Real-time data visualization and logging DATA INTEGRATION Command-line tools for direct data access and integration SPECIFICATIONS Parameter Temperature Probe operating range[1] Accuracy Accuracy Accuracy Resolution Repeatability Response time Samples rate Factory calibrated Probe only IP rating Warm-up time Probe IP rating SPECIFICATIONS Value Power supply – -55 to 75 °C Typ., 25 °C ±0.5 °C -10 °C to 75 °C ±1 °C -55 to 75 °C ±2 °C – 0.5 °C Typ. 0.06 °C t63% (75°C) 8 sec – 240 ms Individually[2] Yes – – 64 – At 25°C, minimum, 5 min following power-up – 65 – ○ Virtual COM Port (VCP) communication protocol ○ 3-point user calibration mechanism Current consumption 12 mA Mechanical Colour – Cyan – Weight Without USB cable 76 g Housing and USB cable Temperature operating – 0 to 70 °C range Humidity operating range Non-condensing 10 to 90 %RH Material – ABS – IP rating[3] – 51 – System galvanic isolation – None – USB cable length – 1 (3) m (ft) Miscellaneous ADC resolution – 12 bits Long-term stability – Yes – Temperature By the manufacturer Yes – compensated Lifetime – 5 years [1] [2] ALSO AVAILABLE Traceability certificates Powered through a USB port At 5V Only if cable is not moved/flexed while the temperature is below 0°C. Each sensor is individually conditioned by the manufacturer of the semiconductor sensor chips, in the best stable conditions and their correction coefficients are recorded in each of them. If water condensation or splashing is possible, protect the USB cable and the cable converter using extra precautions. Extra housing may be required depending on the application.
