USB TEMPERATURE AND RELATIVE HUMIDITY SENSOR The TRH200 is specifically designed for environmental temperature and humidity acquisition. Its exposed sensor allows a more precise temperature measurement of hard surfaces. With its factory calibrated, linearized and temperature-compensated digital sensor ◌ Surface temperature measurement ◌ Server rooms ◌ Manufacturing ◌ Pre-certification chip, it is field interchangeable. Thanks to its precision electronics, extremely small variations in temperature and humidity can be detected using a standard USB port. This product has a typical accuracy at 25°C of ±0.3°C and ±2 %RH. ◌ 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 Parameter Temperature Probe operating range[1] Accuracy Accuracy Resolution Repeatability Response time Factory calibrated Long term drift Relative humidity Probe operating range[3] DATA INTEGRATION Command-line tools utilities for direct data access and integration Accuracy Resolution Temperature coefficient ○ Virtual COM Port (VCP) communication protocol ○ 3-point user calibration mechanism Temperature coefficient Repeatability Hysteresis Factory calibrated Long term drift Non-condensing Typ., 25°C, 20 to 80 %RH Max., 25°C, 0 to 100 %RH Typ. 10°C to 60°C, 50 %RH 10°C to 60°C, 90 %RH – – Individually[2] Normal condition Traceability certificates ALSO AVAILABLE Dracal Technologies Inc.

Each sensor is individually conditioned by the manufacturer of the semi-conductor sensor chips, in the best stable condition and their correction coefficients are recorded in each of them. [3] If water condensation or splashing is possible, it is recommended to install the probe pointing down to reduce the risk of water build-up in the sensor. If water splashing is possible, protect the sensor and cable converter using extra precautions. E

USB-TRH200 Typical temperature and humidity tolerances PRODUCT DIMENSIONS RH%: %RH maximal tolerance T°C: typical tolerance CAUTION: Keep in mind that electromagnetic interferences (EMI) may adversely reduce the precision of the sensor. Avoid using this unit close to EMI sources such as or, transformers, high voltage and fluorescent light. NOTE: This product is not waterproof and must be protected if contact with water is possible. If the probe is inadvertently splashed or submerged in water for a few seconds, unplug the unit, shake it up and let it dry. TIP: Avoid installing the sensor in a...
