SERVICE & CALIBRATION
24/7 Global Customer Care and Calibration Service
Reliable service and calibration support around the globe.
Main locations in Germany (Heitersheim) and China (Shenzhen), plus subsidiaries in several other countries, keep response times short on every continent. Our most important support begins after the sale.
What We Calibrate
Three accredited calibration disciplines, each with its own reference standards. If your instrument is not listed, contact us and we will confirm what is possible for that model.
Flow Calibration
Thermal mass flow meters and flow sensors in compressed air and technical gas lines.
- Accuracy
- < 0.5% o. RDG
- Range
- 0 – 260 m/s (20 °C, 1000 mbar)
- Pressure
- 0 – 0.7 MPa
- Pipe sizes
- DN8 – DN100
- Medium
- Compressed air and technical gases
- References
- Sonic nozzles, laminar flow elements, turbine meter, Coriolis meter
Dew Point Calibration
Dew point and frost point sensors used to verify dryer performance and air quality.
- Accuracy, frost/dew point
- ≤ ± 0.1 °C
- Accuracy, temperature
- ≤ ± 0.07 °C
- Calibration range
- −70 – +20 °C Td
- Reference
- MBW 373 dew point hygrometer / dew point mirror
Oil Vapour Calibration
Oil vapour sensors monitoring residual oil content in compressed air systems.
- Accuracy
- > 0.5 ppm at ±1.8% uncertainty; < 0.5 ppm at ±2.5% uncertainty
- Gas
- Isobutylene in synthetic air
- Reference
- Traceable and certified gas
- Range
- 0.000 – 10.000 mg/m³
- Zero point
- Multiple activated carbon filtration for accurate zero-point calibration
Two Ways to Keep Your Instruments Calibrated
Both routes end with a traceable certificate. The difference is whether your measuring point has to pause while the work is done.
- Option 1
Send Your Sensor In
You ship the instrument to your nearest laboratory. It is cleaned, inspected, calibrated and returned with a certificate.
- DowntimeMeasuring point is offline while the sensor is away
- You ReceiveYour own instrument back, recalibrated
- Best ForPlanned shutdowns, or where a spare is available
- To StartComplete an RMA form and ship the unit
- Option 2
Exchange Calibration
A calibrated replacement arrives first, already carrying your sensor settings. Swap it on site and return the original within four weeks.
- DowntimeNone — you swap at a time that suits you
- You ReceiveA calibrated unit with a fresh certificate
- Best ForMeasuring points that cannot go offline
- To StartSend us the model and serial number
Applies to dew point meters and air quality instruments.
Sending in a Sensor for Calibration
Four steps get your instrument into the queue without follow-up questions. The RMA form is the only paperwork required.
- 1
Complete an RMA FormEmail us a copy and enclose a printed copy inside the package with the sensors.
- 2
Add the Sensor DetailsModel number, serial number and any other identifying information.
- 3
Describe the Work NeededCalibration, repair, output exchange, or a combination.
- 4
Pack It SecurelyUse the original transport case where possible so the sensors arrive undamaged.
What Happens in Our Laboratory
Calibration at SUTO iTEC is a complete process, from cleaning the sensor, through precise testing of every component, to restoring its original accuracy.
- 1
Customer Sends SensorYou ship the instrument with its RMA form.
- 2
Arrival and Check-inThe unit is logged, identified and queued.
- 3.1
Calibration Station — As FoundPerformance is recorded exactly as received, before any work.
- 3.2
Calibration Station — As LeftPerformance is recorded again after cleaning and adjustment.
- 4
Final TestA full functional check confirms the instrument is within specification.
- 5
Packing and ShippingThe sensor is packed with its certificate and returned to you.
More than Recalibration
Every calibration includes professional cleaning and a thorough inspection of all components, not just the measurement itself. Instruments come back working as well as they read.
State-of-the-art Calibration Laboratories
SUTO iTEC operates advanced calibration laboratories in Germany, Hong Kong and China. Each is equipped with traceable reference standards for dew point sensors, flow meters, leak detectors and other measurement instruments, so certified work is never far from your site.

Frequently Asked Questions
Which instruments can SUTO iTEC calibrate?
Flow meters and flow sensors for compressed air and technical gases, dew point and frost point sensors, and oil vapour sensors. Each discipline has its own reference standards, listed further up this page. If your instrument is not covered there, contact us and we will confirm what is possible for that model.
How long will my instrument be away?
Lead time depends on the instrument type, the work required and current laboratory workload, so we confirm a date when your RMA is received. If a measuring point cannot go offline at all, the exchange calibration service avoids the wait entirely: a calibrated replacement arrives before you return your own unit.
What is included besides the calibration itself?
Professional cleaning, a thorough inspection of all components, and a final functional test before the instrument is packed. The certificate documents the measurement, but the service restores the instrument as a whole.
What do as found and as left results mean?
As found records how the instrument performed exactly as it arrived, before any cleaning or adjustment. As left records performance after service. Together they show whether the instrument had drifted, which is what allows your quality team to assess any risk to earlier measurements.
Can I avoid downtime while my sensor is calibrated?
Yes. With the exchange calibration service a pre-calibrated sensor carrying your existing settings is delivered first. You swap it on site and return the original within four weeks, so the measuring point is never unmonitored.
What has to be included in the shipment?
A printed RMA form inside the package, plus the model and serial number of every instrument and a description of the work required. Pack the sensors in their transport case where possible so they arrive undamaged.
