Voltcraft PL-135HAN Hot-Wire Anemometer with Temperature Measurement and USB Interface

The Voltcraft PL-135HAN is a professional hot-wire anemometer engineered for high-precision airflow velocity measurements. This device is capable of detecting air speeds ranging from 0.1 to 25 m/s, making it a reliable tool for both low-flow and high-flow environments. It features an integrated temperature sensor that allows for simultaneous monitoring of air temperature alongside velocity, providing comprehensive data for environmental analysis. The inclusion of a telescopic probe ensures that users can easily reach ventilation shafts, ducts, and other confined spaces, while the built-in USB interface facilitates seamless data transfer to a computer for further processing and documentation.

Advantages

This anemometer stands out due to its hot-wire sensor technology, which offers superior sensitivity and accuracy compared to traditional vane-type devices, especially at low air speeds. The telescopic design of the probe significantly enhances versatility, allowing for measurements in difficult-to-access locations without compromising the stability of the reading. Furthermore, the ability to record temperature and airflow simultaneously saves time during inspections. The USB connectivity ensures that data management is efficient, supporting professional reporting and long-term monitoring tasks in various technical environments.

Suitable for

• HVAC system testing and maintenance
• Ventilation and air conditioning analysis
• Environmental monitoring in laboratories
• Industrial airflow diagnostics
• Checking air quality and flow in cleanrooms

This device may not be suitable for environments with extremely high temperatures or corrosive gases that could damage the sensitive hot-wire element. It is also not intended for use in explosive atmospheres or for measuring liquids.

Key specifications

• Air velocity measurement range: 0.1 to 25 m/s
• Temperature measurement range: 0 to 50 °C
• Sensor type: Hot-wire
• Connectivity: USB interface
• Probe type: Telescopic

To use the device, extend the telescopic probe to the desired length and position the sensor head directly into the airflow, ensuring the sensor is oriented according to the markings for optimal accuracy. Power on the unit and select the desired measurement units. Allow the sensor a brief moment to stabilize before recording the readings. If using the USB interface, connect the device to a computer using the appropriate cable and software to log data in real-time.

What to consider before purchase

• Ensure the measurement range meets your specific application requirements
• Verify that the probe length is sufficient for your ventilation ducts
• Check compatibility with your computer operating system for data transfer
• Consider the need for periodic calibration to maintain measurement accuracy

For the most accurate results, ensure the hot-wire sensor is kept clean and free from dust or debris. Always allow the device to acclimate to the ambient temperature of the measurement environment before taking readings.
