FAQ
Q: How do I choose the right probe?
A: The default probe works for most environments. For dusty conditions, select a waterproof probe. For high-temperature conditions, use a high-temperature probe. For specialized needs, dust-resistant or corrosion-proof probes are available.
Q: What signal transmission options are supported?
A: The device supports RS485, 4-20mA, 0-5V, and 0-10V. It can also be upgraded to WiFi, 4G, or Ethernet for real-time monitoring. Data can be connected to a computer via an RS485-to-USB module or uploaded directly to the cloud.
Q: Can the device support multi-point monitoring?
A: Yes. With data loggers, the system can collect up to 32 parameters simultaneously. The data can then be uploaded to the cloud for centralized management and remote monitoring.
Q: What display options are available?
A: You can choose from high-brightness LED digital displays, low-power LCD displays, or vivid OLED displays for clear and intuitive data visualization.
