The PCE-ERS 100 refrigerant scale is a professional instrument designed for precise control of refrigerant quantities during filling, emptying, recovery and maintenance operations on refrigeration systems, air conditioners, heat pumps and HVAC installations. It allows the technician to weigh cylinders accurately, checking the amount of gas added to or removed from the system and reducing the risk of incorrect charging, waste or non-compliant service work.

The maximum weighing range is 100 kg, with 0.01 kg resolution and ±0.01 kg accuracy. These features make the PCE-ERS 100 suitable for both small air conditioning units and larger refrigeration systems where the refrigerant mass must be carefully controlled. A stable and accurate reading helps the technician dose the gas correctly and follow the quantities specified by the system data or operating procedures.

The weighing platform measures 230 x 230 x 45 mm and is equipped with a non-slip rubber surface. This platform allows cylinders to be positioned more safely during charging or recovery operations, limiting accidental movement and improving stability during measurement. The compact structure allows use in workshops, on job sites, in technical rooms, refrigeration plants, HVAC areas and customer service applications.

The external control unit is connected to the platform by a 1.3 m cable. This configuration allows the weight value to be read from a convenient position, even when the cylinder is placed close to the system or in a confined space. The 2.8" backlit LCD makes reading easier in technical rooms with limited lighting, plant compartments, maintenance areas or situations where visibility is not ideal.

The PCE-ERS 100 allows several measurement units to be selected, including kg, g, lb, oz and lb/oz. This flexibility is useful for technicians working with international documentation, cylinders marked in different units or maintenance procedures requiring quick conversions. The tare function allows the weight of the cylinder, container or accessories to be zeroed, so that only the actual refrigerant variation during transfer is measured.

The control function with acoustic alarm allows a reference weight to be set, at which the device alerts the operator. This function is particularly useful when filling a refrigeration circuit, because it helps monitor the quantity being added and allows the technician to act promptly when the desired value is reached. The acoustic alarm supports the technician when attention is divided between the scale, pressure gauges, hoses and the system.

The instrument can be powered by a 9 V battery or by a 6 V DC 200 mA power supply. The operating time is approximately 60 hours, while automatic switch-off after 15 minutes helps extend battery life when the instrument is not in use. This dual power option makes the scale suitable for both mobile service work and continuous use in workshops or technical laboratories.

The scale includes a USB interface, useful for connection and data handling according to the functions provided by the device. The IP40 protection class makes it suitable for controlled technical environments, workshops, plant rooms and maintenance departments. Operating conditions are 0 - 40 °C with 0 - 90% RH, while storage conditions are 0 - 40 °C with 0 - 90% RH.

The instrument weighs approximately 2061 g and the display unit measures 160 x 85 x 38 mm. The supplied carrying case makes transport easier and protects the scale when moving between workshop, service vehicle, job site and technical rooms. This is important for refrigeration and HVAC technicians who need to use the instrument at several locations while keeping the device organised and protected.

The PCE-ERS 100 is suitable for refrigerant charging, gas recovery, checking remaining quantities in cylinders, monitoring weight during maintenance operations and supporting technical service procedures. In refrigeration systems, air conditioning and heat pumps, the correct refrigerant quantity is essential to ensure performance, energy efficiency, operating stability and reduced risk of faults.

For correct use, the platform should be placed on a stable and level surface, vibrations should be avoided during measurement, the tare function should be used before transfer and the cylinder should be properly positioned on the non-slip surface. During filling or emptying, the weight variation should be monitored progressively and the alarm should be set when a defined quantity must be reached.

The PCE-ERS 100 refrigerant scale is therefore a practical and professional solution for technicians who need to dose and control refrigerants accurately in HVAC and refrigeration systems. The combination of 100 kg measuring range, 0.01 kg resolution, non-slip platform, backlit display, tare function, acoustic alarm, dual power supply and carrying case makes it suitable for everyday maintenance, installation and service work.
