ServersCheck's In-House Calibration lab Regardless of the vendor, sensors do drift over time due to several phyiscal factors.

When used indoor it is recommended to check the accuracy of your sensors at least once a year.
For outdoor use, it is recommended to check them every 6 months.

Our in-house lab is fully equipped to test the accuracy of your temperature & humidity, infrared spot or thermal image sensors with measurements traceable to NIST.

Order Calibration

Calibration & testing of IP-based sensors.
That's our lab's expertise.
Get calibration certificates for your sensors.
All tests are performed against NIST traceable measurements and as per ISO 17025 standards.
Temperature: 3 reference points at 0°C, 20°C & 25°C.
Humidity: 3 points at 35, 50 & 70 %rH at 35°C.
Optional Hot Swap: we ship you calibrated sensors first; you then return your sensors.

NIST Traceable.
We perform all of its measurements against calibrated NIST traceable reference meters.

Certificates contain all required information and reference to the unbroken chain of measurements as per ISO standards.

All accuracy testing & calibration certification work is done as per ISO 17025 standards. However our lab is currently not ISO 17025 accreditated.

Calibration Certificate.
Certificate icon
Our in-house lab issues a unique calibration certificate per sensor it tests. We do strictly follow the ISO 17025 standards when testing your sensors.

We verify if your sensors are within tolerance for the different test points. Certificates include the calibration equipment used with serial numbers. The calculated uncertainty, calibration date and due date.

Temperature Calibration.
Sensors do drift over time and will retaining precision, there are no longer accurate. That's why annual calibration is recommended. This applies to sensors of most vendors, including us.

Our lab tests temperature sensors against 3 temperature reference points. 0°C, 20°C and 25°C. Test are done in an environmental chamber. Measurements are compared against a calibrated NIST traceable temperature sensor.

Humidity Calibration.
Humidity icon
Like temperature sensors, annual calibration is recommended due to sensor drifting. When used in a dirty environment (air pollulants) or outdoors, then the frequency should be every 6 months for a calibration. With our hot swap option, we ship you a calibrated sensor before your return yours.

We check your sensor against 3 humidity points (35%, 50% and 70%). Tests are performed using one or more calibrated and NIST traceable reference humidity sensors.
