The BT-280 is the best smart companion for keeping an eye on the quality of your water. It can track pH, ORP, and temperature all at once, without any extra work. It’s a must-have in power plants, municipal wastewater facilities, water supply systems, pharmaceuticals, chemicals, food processing, and more since it fits directly into your workflow.
It maintains an eye on the pH and ORP levels of the solution all the while, so you can be sure that your processes stay stable and meet all the rules.

Innovative Application Scenarios
“Process Guardian” for Critical Production Lines
- Food and drinks: Check the pH levels of the syrup producing, bottle washing water, and cleaning processes to make sure they meet food safety requirements. If the pH number is odd, we will quickly tell you to avoid waste.
- Pharmaceutical: Track pH levels in drug formulas and sterile water systems – comply with GMP standards, with reliable data for audit tracking.
- Chemical reaction: Monitor pH/ORP during the reaction process – trigger automatic doses through a relay to keep the reaction on track and reduce human involvement.
Compliance Navigator for Wastewater and Water Supply
- Urban wastewater: Automatically record pH/ORP data to meet discharge requirements, without the need for manual recording of values, saving time.
- Urban water supply: Monitor the pH value of reservoirs and water distribution, detect abnormal acidity and alkalinity as early as possible, prevent pipeline corrosion, and ensure the safety of drinking water.
- Industrial wastewater: Through continuous monitoring, ensure that the wastewater meets local discharge limits and avoids punishment.
Space saving solution for compact settings
- Small Factory: A small control cabinet suitable for craft breweries, specialty food factories, or laboratory testing lines, providing industrial grade performance without occupying additional space.
- Renovation project: Easy to install in old workshops with limited space – the size of 91 × 91mm is suitable for standard old cabinets.
- Mobile testing: When used in conjunction with a portable power source, it can be used for temporary monitoring (such as emergency wastewater treatment, construction site runoff) – flexible and fast deployment.
The fundamental driver behind remote maintenance
- Check the pH level of village wells or small reservoirs to make sure they have enough water. BT280 works well even in tough situations and doesn’t need a lot of care.
- Aquaculture: Make sure the water quality on fish farms is good, and utilize relays to vary the quantity of medicine to keep the fish healthy and lower the death rate.
- Cooling tower: By regularly watching the pH level of the water that flows through it, you can stop scaling and corrosion, make your equipment last longer, and save money on maintenance.
Multi dimensional comparison between A-series controller and BT-280
Core positioning
| Dimension | BT-280 | A Series (A10PR/A20PR/A30PR) |
|---|---|---|
| Core positioning | Basic industrial grade, focusing on “essential monitoring” | Full scene coverage, divided into “universal/advanced/compact” models |
| Target users | Small and medium-sized enterprises, single monitoring demand scenario | Large factories, complex working conditions, and limited space scenarios |
| Core advantages | High cost-effectiveness, simple operation, stable and durable | Comprehensive functionality, flexible adaptation, and scene segmentation |
BT-280 is “sufficient, easy to use, and affordable” for most industries’ basic monitoring needs. The A series has different models for different uses, such as A10PR for general use, A20PR for complicated work environments, and A30PR for small spaces, so it can meet a wider range of industrial needs.
Operation and Calibration
| Function | BT-280 | A Series (A10PR/A20PR/A30PR) |
|---|---|---|
| Shortcut key design | Support “one click calibration” and “3-second factory recovery” | Supporting similar shortcut operations, A20PR adds an additional “alarm information shortcut key” |
| Menu logic | Four primary menus | The menu structure is consistent, but the A20PR sub menu is richer |
| Data Preview | Support secondary menu parameter preview | Consistent functionality, A20PR can display more real-time data |
Both focus on “low threshold operation”, but the A series (especially A20PR) is more detailed in the subdivision of professional functions, suitable for scenarios that require “precise debugging”.
| Calibration method | BT-280 | A Series (A10PR/A20PR/A30PR) |
|---|---|---|
| Calibration mode | Two point/three-point calibration (compatible with standard solutions such as 4.00/6.86) | Consistent functionality, A20PR supports free setting of calibration points (more flexible matching of special standard fluids) |
| Warm supplementation | Support manual/automatic temperature compensation | A20PR/A10PR supports custom temperature compensation coefficient (adapted to the temperature characteristics of special solutions) |
BT-280 calibration logic is “fixed”, beginners do not need to adjust parameters; The A-series allows professionals to customize calibration points and temperature compensation coefficients, suitable for scenarios such as pharmaceuticals and semiconductors that require extremely high precision.
