Cyclic Self-Cleaning, Utility Model Patent M617481
AquaPack
Sensor probes
that clean themselves.
The probes are cleaned automatically after every measurement, so there's no wading in every few days to wipe them.
Solar powered, it runs on the water or along the bank.
AquaPack is a solar-powered water quality sensing system developed in-house by YenProtek, featuring patented cyclic self-cleaning for stable, long-term monitoring of aquaculture water quality.

Patented Cyclic Self-Cleaning
Dirty probes,
unreliable data.
Biofilm on the sensor probes doesn't just skew the readings; it also makes the sensors age faster. AquaPack keeps fouling down from before each measurement to after it.
Patented self-cleaning removes particles & biofilm!
-
Before Measurement
The water sample is treated first, reducing suspended solids and microbial attachment.
-
After Measurement
A cleaning cycle starts automatically, removing microbes attached to the sensor probes and reducing biofilm growth.
-
Less Wading, Steadier Data
Manual cleaning is needed far less often, data stays stable over the long term, and the probes are less prone to aging from fouling.
Granted a utility model patent (No. M617481). Sensor probes still need regular calibration, and dissolved oxygen membrane caps need regular replacement. See the sensor specifications and instructions for details.
No Plumbing or Wiring
Set it on the bank.
It starts measuring.
Solar powered, with no plumbing or electrical work and no separate host unit to set up. It runs on the water or along the bank, with no changes to your existing pond layout.
Installation
Afloat on the water,
sampling up close.
With a flotation device fitted, AquaPack floats on the surface and draws water samples right where it sits. Choose a platform to suit your water, or place it on the bank.

Unstable Network, No Lost Data
Data is stored on the device first, so it isn't lost to failed uploads when the signal is weak.
-
Scheduled Measurement
It samples and measures automatically on the schedule you set and uploads the data to the cloud, with no manual logging or sorting.

Frequently Asked Questions
How does self-cleaning work?
Water samples are pretreated before measurement to reduce suspended solids and microbial attachment. After measurement, a cleaning cycle starts automatically to remove microorganisms attached to the sensor probes and reduce biofilm growth. This cyclic self-cleaning technology has been granted a utility model patent (No. M617481).
With self-cleaning, is maintenance still needed?
Self-cleaning greatly reduces how often manual cleaning is needed, but sensor probes are consumables and still require regular calibration. Dissolved oxygen membrane caps need regular replacement, and a damaged pH glass bulb cannot be repaired. For calibration and replacement procedures, please refer to the sensor specifications and usage instructions.
There's no power next to my fish pond. Can it still be installed?
Yes. AquaPack runs on solar power, with no plumbing or electrical work required and no separate host unit to set up. It works whether placed on the water or along the bank.
Can it be used for offshore cage aquaculture?
Yes. AquaPack is suitable for both land-based fish ponds and offshore cage aquaculture, and special industrial-grade acid- and alkali-resistant probes are also available.
Can it automatically turn on paddlewheel aerators when dissolved oxygen is too low?
Yes. With the Smart Control Box, aerators, paddlewheels, and other equipment can start automatically when dissolved oxygen falls below the set value.
What if it breaks?
It comes with a one-year warranty, and an extended warranty is available. If the product fails during the warranty period, there's no need to send it in and wait for repairs: we ship you a replacement right away so your water quality monitoring is back up and running as quickly as possible. After the warranty expires, units can be returned to our factory for repair. Actual warranty terms are subject to your quotation.
Is the App available in my language?
The App and cloud platform offer a multilingual interface, so users everywhere can work in a language they know.
How is pricing calculated?
Pricing is based on the combination of sensors, connectivity, and power options you choose, so you only buy the modules you need. Tell us about your water body and the species you farm, and we'll recommend a configuration and provide a quote.
