UA54-H2S

Product catalog summary

Overview: The UA54-H2S is an electrochemical Hydrogen Sulfide (H2S) density transmitter that provides real-time data transmission via USB. It is recognized as a serial port on operating systems and can be accessed using AT commands. The device supports multi-channel sensor configurations and does not store data internally, requiring external recording on PCs or Android devices.

Operating Conditions: Temperature: -40 to 50°C, Humidity: 15-90% R.H (non-condensing).
Power Consumption: 5V, Max. 100mW.

Hardware and Software:

USB Port: USB 2.0 Type A Plug.
Output Signal: USB digital, CDC Device (AT Command).
LED Indicators: Various statuses including warming-up and connection failures.
Software Support: Tapaculo Lite for PC and Tapaculo Mobile for Android, available for download.

Calibration: The device includes an individual calibration certificate and supports two-point calibration with 49 ppm H2S calibration gas mixtures.

Accessories: Optional converters for USB to LAN (RN171) and USB to WIFI (RN172) are available, supporting cloud monitoring and MODBUS TCP/HTTP data transmission.

Applications: Suitable for industrial safety monitoring, bio-labs, sewage treatment plants, and animal farms.

Cautions: Avoid volatile organic compounds, long-term exposure to high concentrations, sudden humidity changes, and static electricity to maintain sensor performance.

Catalog excerpts

Electrochemical H2S Density Transmitter via USB UA54-H2S • Real-time H2S density, Temperature transmitter • Electrochemical H2S gas sensor embedded • Individual Certificate included • Recording/Monitoring Software on Win/Mac/Linux • Android Recording App. The UA54-H2S device has an electrochemical Hydrogen Sulfide(H2S) sensor inside. It transmits the measured H2S density and temperature information in real-time via the USB connector. The UA Series is automatically recognized as a serial port on the operating system and accessed using the AT command. Multiple USB connections of the UA device could compose the multi-channel sensor. The sensor data is not stored in the UA, but recording in PC and Android device. 128CH real time monitoring software on pc, Tapaculo Lite is downloadable on our website(www.radionode365.com). And android real time recording application is also available from google play store. The optional RN17X model helps UA series for you to setup remote web monitoring system. • Volatile organic compounds (VOCs) should be 2. Screw Hole avoided in applications where electrochemical sensors are used because they either dissolve in the electrolyte or adsorb onto the sensor’s housing. • Long term exposures and high concentrations may affect the performance characteristics Contact Information • Sudden changes in humidity cause short-term transient signals • Avoid contact with conductors. • Static electricity can cause distorted values.
