MALCOM RCX-O device This is an optional module for measuring oxygen concentration. Measurement range: 50 ~ 5,000 ppm or 1,000 ~ 10,000 ppm.
It is added to the main RCX-1 (or RCM-S) system. Therefore, the RCX-O itself is not a standalone system, and its accessories are integrated with the main system.
Accessories and components related to the use of the RCX-O module include:
Base Unit: An RCM-S or RCX-1 base unit is required for power supply and data storage.
O₂ Sensor: This is the main component of the RCX-O module for measuring oxygen concentration.
Heat-resistant case: Necessary to protect the entire system (main unit and RCX-O module) when passing through the reflow oven at high temperatures.
Ni-MH rechargeable batteries or AAA batteries: Provide power to the system while it's operating inside the oven.
USB cable: Used to transfer data from memory to the computer (if Bluetooth is not used).
Specialized analysis software (TMR-1 Software): Used on a computer to simultaneously display and analyze temperature, oxygen concentration, and other parameters on a single screen.
Thermocouples and mini-connectors: Although used for temperature measurement, they are essential accessories of the main system (RCM-S/RCX-1) and are often used concurrently when measuring O₂.




MALCOM RCX-O Check the oxygen concentration from the entrance to the exit of the reflow oven!
Accurately measure the oxygen concentration on the board! Visualize the entire furnace interior.
Measure the oxygen concentration in real time at the board placement position.
Compare with the oxygen concentration meter attached to the reflow equipment, allowing for more accurate status confirmation.
● Profiles changes in oxygen concentration from the entrance to the exit of the reflow oven.
● Supports measurements during production (heating), enabling efficient work.
● Select from two measurement ranges depending on the control width (50 to 5,000 ppm, 1,000 to 10,000 ppm).
