The digital manometer C.A 850 from Chauvin Arnoux is a precise measuring instrument for determining overpressure and differential pressure. It is particularly used for monitoring and maintenance of systems requiring pressure values in the range of −6.89 to +6.89 bar, such as air conditioning systems, medical devices, or air pressure monitoring systems. The device features a large display area and intuitive operation, ensuring easy readability of measurement values even in poor lighting conditions. The backlighting further enhances the readability of the display. Its compact and lightweight design, with dimensions of 182 x 72 x 30 mm and a weight of 220 g, makes it suitable for mobile applications.

Applications

The manometer C.A 850 is used in various technical and medical application areas. These include tire pressure testing, air conditioning system maintenance, monitoring of air pressure systems, and use in medical devices where precise pressure measurements are required. The versatility of the device enables its use in different industries where reliable and accurate pressure measurement is necessary.

Functions and Equipment in Detail

The device features several useful functions that facilitate the measurement process. The Hold function allows a measured value to be held, enabling it to be read even if the pressure changes. The minimum and maximum value monitoring with timestamp allows documentation of extreme values during a measurement, which is helpful for analyzing pressure trends. Automatic power-off protects the battery and extends the device's operational life. The display supports various units of measurement, including psi, bar, mbar, inH2O, mmH2O, mmHg, ozin², kg/cm², kPa, ftH2O, inHg, and cmH2O, allowing adaptation to different requirements.

Technology Explained Simply

The measurement range of the device is between −6.89 and +6.89 bar, equivalent to a range of −100 to +100 psi. The precision is ± 0.5 % of full scale ± 1 pt, ensuring high accuracy in measurements. The resolution of 0.01 psi allows for fine representation of measurement values. The maximum pressure level that can be withstood for short periods is 10.33 bar (±150 psi), providing a certain degree of overload protection.

Compatibility and Accessories

The manometer C.A 850 is designed for use with various pressure systems, particularly in air conditioning systems, medical devices, and air pressure monitoring systems.

Mounting and Installation

The device is designed as a handheld measuring instrument and requires no mounting or installation. Operation is performed via buttons on the device, which control various functions such as HOLD, Min./Max., and power on/off.

Operational Advantages

The combination of high precision, compact design, and versatile functions makes the C.A 850 a reliable tool for technical and medical applications. The backlighting and large display improve readability, while automatic power-off extends battery life. Support for various units of measurement increases flexibility when used in different working environments.
