Replaceable vs. Non-Replaceable Probe Guide
This page explains how to decide whether a probe or sensor can be replaced. It does not claim that a sensor is user-replaceable unless the exact product document or Rovynel Support confirms it.
Current verified status
The current public listings identify complete products and measurement channels, but they do not provide confirmed user-replaceable element part numbers or cross-model probe interchangeability. Treat replacement status as model- and hardware-revision-specific.
Decision checklist
- Identify whether you own a complete monitor, a standalone RS485 probe, or an environmental air monitor.
- Record the product title, SKU, hardware revision, connector, cable length and labels.
- Confirm whether the service part is a complete probe assembly, an individual sensing element, a cable, or the display.
- Confirm power, polarity, connector pinout, communication protocol, address, register map and scaling where applicable.
- Confirm calibration or verification requirements after replacement.
- Do not energize or immerse a proposed replacement until compatibility is confirmed in writing.
Six-product status table
| Product | Known structure | Replacement action |
|---|---|---|
| RVN-WQ8-LORA | Floating probe plus LoRa-connected display | Confirm the exact paired probe or display revision with support |
| RVN-WQ7-RS485 | Matching wired probe and WiFi display | Do not substitute a generic RS485 probe without protocol confirmation |
| RVN-WQ7-WIFI | Long-range wireless sensor and WiFi display | Confirm the paired radio and hardware revision |
| Standalone RS485 probe | Complete integration probe | Replace as an exact probe assembly unless the supplied document identifies serviceable elements |
| RVN-HYDRO-6IN1 | Air and nutrient-water sensing channels | Identify the exact failed air or water sensor before ordering |
| TH-WIFI | Remote SHT40 air probe and display | Confirm connector, cable and hardware revision |
After replacement
- Inspect installation and leak or moisture exposure.
- Restore the exact configuration and communication settings.
- Complete required calibration or comparison checks.
- Record the service date, part identity and baseline readings.
- Keep manual backup testing until performance is stable.
Request compatibility confirmation before ordering a service part.
