Why calibrating measuring instruments is so important
Measurement accuracy. Standard safety. Operational guarantee.
For HVAC professionals, accurate heating water analysis is essential: VDI 2035, ÖNORM H 5195-1, and SWKI BT 102-01 set clear requirements for pH value, conductivity, and other parameters such as oxygen. But what good is the best measuring device if the measurement itself is faulty? This is where calibration comes in – and it is much more than just technical stuff. It is fraud protection, quality assurance, and energy efficiency all in one.
Small deviations – big consequences
Even a minimally inaccurate pH value can have serious consequences today: an incorrect assessment of aluminum components can promote corrosion, cause heat exchangers to fail, or jeopardize warranty claims. Similar risks arise from incorrect conductivity measurements—from sediment buildup to total failure of entire circuits due to clogged passages.
That’s why regular calibration is necessary – otherwise, you’re basically working blind. Fortunately, the WaterBoy app reminds you when calibration is due.
Calibration made easy – with WaterBoy & app
With the WaterBoy dual measuring device for pH value and conductivity, we at UWS focus on ease of use without compromising on quality:
- Simple 1- to 3-point calibration – guided step by step in the app menu
- Automatic reminder when calibration is overdue
- Calibration solutions (pH 4.01 / 7.01 / 10.01 and two conductivity ranges) are included in the measuring case.
- Documentation: The app creates PDF reports with timestamps, object references, and the name of the person responsible—suitable for handing over to customers or for operational evaluations. The measurement reports also indicate whether the measuring device was correctly calibrated.
Practical tip: Rinse the probe thoroughly with distilled water between calibration points – clean electrode = clean results.
WaterBoy measuring case
The UWS WaterBoy measuring case contains everything the HVAC specialist needs to measure data in accordance with the VDI 2035, ÖNORM H 5195-1 and SWKI BT 102-01 standards in two L-BOXXES.To the product
Why this is not just technical trinkets
Calibration is the foundation on which everything else rests:
- Measurement reliability: Only a correctly calibrated device provides accurate data.
- Warranty and liability protection: Available with documentation – if you can prove it, you’re on the safe side.
- Energy efficiency: Optimal heating water-based operation with the right parameters ensures precise control, lower flow temperatures, and longer service life for heat exchangers.
- Error prevention: It avoids costly rework due to incorrectly set replenishment or system errors.
In short: Without calibration, you are actively distorting your measurement image—and laying the foundation for future complaints, inefficient operation, or even damage.
WaterBoy calibration: How it works
Conclusion: Those who calibrate sell quality
Measuring devices without calibration are like a compass without north—you get numbers, but no direction. For HVAC companies, calibration is not only mandatory—it is visible proof of quality, makes work easier, and serves as a customer contract all in one.
With the WaterBoy measuring device, the intuitive app, and the calibration solutions, you are sending a clear message: for quality, compliance with standards, and safe use—whether during handover, maintenance, or commissioning.
