Long-Term Climate Precision: Reliable Sensor Readings Down to a Tenth of a Degree

Long-Term Climate Precision:
Reliable Sensor Readings Down to a Tenth of a Degree

Sensirion Temperatur- und Feuchte Sensoren der SHT Familie

Whether in the pharmaceutical industry, cold chain monitoring, or high-end data loggers: when every tenth of a degree matters, stable measurement values are not a nice-to-have — they are essential.

After all, a measurement is only valuable if you can rely on it. Today, tomorrow, and for many years to come.

This is exactly where the SHT43 and SHT45 temperature and humidity sensors from SENSIRION demonstrate their strengths. They not only deliver exceptionally precise results, but also maintain outstanding stability and reliability over the long term:

More efficient calibration
Easier audits
Consistently reliable measurement data

SHT43 – When Documented Reliability Matters

The SHT43 stands for verified precision. Every single sensor undergoes an individual, accredited calibration in accordance with ISO/IEC 17025:2017. The temperature measurement is verified at three defined points: −30 °C, +5 °C, and +70 °C.

Each sensor comes with a unique serial number and an individual 3-point calibration certificate.

The calibration data can be accessed at any time via SENSIRION’s Libellus platform. This makes the SHT43 a strong choice for applications where traceability, documentation, and long-term stability are essential.

SHT43 – The Facts:

Temperature accuracy: ±0.48 °C
Humidity accuracy: ±1.8% RH
Long-term drift: less than 0.01 °C per year

This makes the SHT43 a strong choice for applications where traceability, documentation, and long-term stability are essential.

SHT45 – Maximum Accuracy, Ready to Use

Do you need maximum precision but can do without a separate calibration certificate?
Then the SHT45 is the right choice. Install it, read it out, and get reliable measurement values.

Each sensor is individually tested and calibrated. The calibration data is already stored in the sensor, so no additional adjustment by the user is required.

The Facts:

Temperature accuracy: ±0.1 °C
Humidity accuracy: ±1% RH
Typical long-term drift: less than 0.03 °C per year

The SHT45 combines maximum measurement accuracy with easy integration and an attractive price-performance ratio.

Greater Measurement Reliability with Integrated Sensor Heating

Humidity can put considerable strain on sensors. That is why the SHT43 and SHT45 feature a heater integrated directly into the CMOSens® chip.

It removes condensation, regenerates the sensor, and helps ensure reliable measurement values even under the most demanding conditions.
