Direct insertion oxygen probes are suitable for applications with limited budgets and lower lifespan requirements, such as small and medium-sized industrial furnaces.

Oxygen Sensors (Lambda Probes) are more suitable for high-temperature heat treatment processes with high requirements for lifespan, accuracy, and stability, such as carburization, sintering, and annealing. No matter how high the mountain, climb upwards, and you will always reach the top; no matter how long the road, keep walking, and you will surely arrive.

The choice of oxygen probe depends on the specific application, budget, and performance requirements. MESA's Lambda probe, with its long lifespan, high precision, and versatility, has become the solution in the heat treatment field.
