Chauvin Arnoux P01156402 Salt cartridge 33% r.f. content_copy

This product is a reference salt in the form of a cartridge, developed as an accessory for thermo-hygrometers, particularly for the C.A 1246 model by Chauvin Arnoux. It is used for calibration and verification of measurement accuracy when recording relative humidity. The cartridge is calibrated to a constant relative humidity of 33 %, making it a reliable standard for field testing. By using this reference salt, users can check the accuracy of their measuring devices under real operating conditions and calibrate them if necessary, ensuring consistent and reliable measurement results.

Accessory for thermo-hygrometers
This accessory is specifically designed for thermo-hygrometers used in industrial measurement technology, facility management, or quality control. It is particularly suitable for the C.A 1246 model, which is used for measuring temperature and relative humidity. The cartridge enables a simple and reproducible testing of device functions without requiring additional laboratory conditions.

Functions and equipment in detail
The salt cartridge generates a defined, stable relative humidity of 33 %, ensured by the physical properties of the salt used. This humidity level is independent of external environmental conditions such as temperature or air circulation, as long as the cartridge is placed in a closed space. Testing is performed by placing the thermo-hygrometer in close proximity to the cartridge, with the device displaying the measured humidity. Deviations from the target value of 33 % indicate a deviation in device accuracy.

Technology explained simply
The technology used is based on the ability of certain salts to generate a constant relative humidity in the surrounding environment by absorbing or releasing water from the air until equilibrium is reached. This equilibrium is at 33 % relative humidity for the salt used. The cartridge is placed in a closed container or suitable chamber to create a stable measurement environment. Measurement is performed directly on the device, without requiring additional equipment or external calibration sources.

Compatibility and accessories
The accessory is primarily intended for the thermo-hygrometer model C.A 1246. However, it is also generally suitable for other devices that allow calibration at a defined humidity point of 33 %. Use requires no additional tools; no special mounting or installation is necessary. The cartridge is simply placed near the device to be tested, ensuring sufficient air circulation to enable even humidity distribution.

Advantages in operation
Regular use of the salt cartridge enables quick and cost-efficient verification of measurement accuracy. It reduces the need for expensive laboratory tests and allows calibration directly at the site of use. The simple handling and stable humidity generation ensure reproducible results, suitable for quality control, maintenance work, or validation of measurement results in various industries. The cartridge is designed for multiple uses, as long as the salt surface is not damaged or contaminated.
