1. What it is used for

The MRS120 scale measures the weight of refrigerant and controls its flow during charging and recovery. You set the refrigerant quantity, minimum 50 g, on the wireless Bluetooth remote control, and the built-in solenoid valve shuts off the flow once the scale has measured the set weight.

The platform has a capacity of 120 kg and a resolution of 8 g, and the supplied valve, which screws into the M10 thread on the platform, lets you charge the system from an inverted cylinder. With A3 refrigerants, such as R290 and R600a, the scale operates in manual mode and gives an audible signal when the set weight is reached.

The platform is powered by 3 rechargeable 18650 batteries charged via the USB-C port, and the remote control by 2 AAA batteries. The rechargeable batteries and charger are not included due to shipping restrictions.

Remote control up to 5 m from the platform. The remote control lets you set the refrigerant quantity and start the process from up to 5 m away from the platform, and runs for up to 30 h on 2 AAA batteries.
Recovery stopped at 80% of cylinder capacity. Once you enter the full cylinder weight, the solenoid valve shuts off the flow during recovery when 80% of this value is reached and triggers an alarm.
Repeat a setting with the REPEAT key. The REPEAT key recalls the last charging or recovery setting, so you do not have to re-enter the values for the next identical quantity.
Calibration without returning to service. The scale is factory calibrated and, if required, can be calibrated on site using a reference weight from 1 to 120 kg.
