The Chauvin Arnoux CA 1730 is a laser distance meter designed for precise measurement of distances up to 60 metres. The device is suitable for applications in the construction and renovation sector, as well as for interior and exterior fittings and the service sector, where quick and accurate room dimensions are required. It enables not only direct distance measurement but also the calculation of areas, volumes, heights, and the addition and subtraction of measurement values. Operation is via an intuitive button interface, and the device is compact and ergonomically designed to ensure safe handling.

Applications

The CA 1730 is used in areas where precise dimensions of rooms, walls, ceilings, or floor surfaces are required. This includes construction projects, renovation work, furnishing, architectural planning, and technical installations. The ability to directly calculate areas and volumes makes the device particularly useful for planning heating, ventilation, and air conditioning systems, as well as for determining material quantities. The offset measurement function, activated via a slider on the rear, allows obstacles such as pipes or columns to be bypassed without interrupting the measurement.

Functions and Equipment in Detail

The device features a four-line display with backlighting, which remains clearly readable even in poor lighting conditions. The display shows multiple measurement values simultaneously, increasing work efficiency. Measurement values can be displayed in various units: metres (m), inches (in), feet (ft), and feet-inches combination (ft+in), enabling adaptation to different regional or industry-specific requirements. An acoustic signal confirms the measurement process, allowing operation without visual monitoring. The memory function stores the last 20 measurements, which can be retrieved or evaluated later.

Technology Explained Simply

The CA 1730 uses a Class II laser with a wavelength of 630 nm to 670 nm and a power below 1 mW, which is safe for use according to the IEC 60825-1 standard. Measurement accuracy is ± 2 mm plus 5 x 10⁻⁵ of the measured distance, ensuring high precision even over longer distances. The range extends from 0.2 metres to 60 metres, with reliable performance even at short distances. The laser automatically shuts off after 30 seconds of inactivity, and the device after 180 seconds, to extend battery life.

Compatibility and Accessories

The device is powered by two AAA batteries (1.5 V), included in the delivery. Battery life is approximately 5,000 measurements. The delivery also includes a transport case, a five-language operating manual, and a calibration certificate. The transport case protects the device during storage and transport. Conformity with standards includes IEC/EN 61326-1, IEC/EN 61010-1, and the laser safety standard IEC 60825-1. The warranty is 2 years.

Mounting and Installation

The device is operated directly by hand and requires no mounting or installation. Operation is via buttons on the front and a slider on the rear for offset measurements. Handling is simple and requires no special preparation. The IP54 protection rating means the device is protected against dust and splashing water, making it suitable for outdoor use or in damp indoor environments. The operating temperature range is from 0 °C to +40 °C without condensation, and storage is possible between -10 °C and +60 °C.

Operational Advantages

The CA 1730 offers high measurement accuracy, long battery life, and intuitive operation. The various calculation functions, such as area and volume measurement, addition, and subtraction, increase work efficiency. The display backlight ensures good readability under different lighting conditions. Automatic shut-off extends battery life, and the IP54 protection rating allows use in various environments. The device is immediately ready for use, as it is delivered with batteries and a protective case.

Protection Rating IP54

The IP54 protection rating means the device is protected against dust and splashing water. This makes it suitable for outdoor use and in indoor environments with increased humidity, such as bathrooms or kitchens. The protection class is sufficient for use in many construction site and service applications.

Battery Operation

The device is powered by two AAA batteries (1.5 V), included in the delivery. Battery life is approximately 5,000 measurements, enabling high usage without frequent battery changes. Automatic shut-off after 30 seconds (laser) and 180 seconds (device) ensures efficient energy use.

Measurement Accuracy

Measurement accuracy is ± 2 mm plus 5 x 10⁻⁵ of the measured distance. This means the deviation for a 10-metre measurement is at most ± 2 mm + 0.5 mm, ensuring high precision even over longer distances. The accuracy is sufficient for professional applications in the construction and service sectors.

Unit Display

The display supports multiple units: metres (m), inches (in), feet (ft), and feet-inches combination (ft+in). This allows adaptation to regional or industry-specific requirements, especially in countries where the metric system is not standardised.

Memory Function

The device stores the last 20 measurements, which can be retrieved at any time. This is useful for documenting measurement values or checking them during later work.

Automatic Shut-Off

The laser automatically shuts off after 30 seconds of inactivity, and the device after 180 seconds. This extends battery life and prevents accidental energy loss.

Operating and Storage Conditions

Operation is possible at temperatures from 0 °C to +40 °C without condensation. Storage is possible at temperatures from -10 °C to +60 °C. The devices are suitable for indoor and outdoor use, provided the operating conditions are met.

Standards Compliance

The device complies with standards IEC/EN 61326-1, IEC/EN 61010-1, and the laser safety standard IEC 60825-1. Compliance ensures safety and reliability during use.

Warranty

The warranty is 2 years, highlighting the reliability and quality of the product.

Delivery Contents

The device is delivered with two AAA batteries, a transport case, a five-language operating manual, and a calibration certificate. It is therefore immediately ready for use.

Dimensions and Weight

Dimensions are 115 x 52 x 32 mm, and weight is 118 g. The device is compact and lightweight, facilitating easy handling.
