When your diesel motor requires dependable emanation checking, NOx Sensors deliver the accuracy Qintai need to meet strict natural benchmarks. As specialized components in present day SCR (Particular Catalytic Diminishment) frameworks, these sensors ceaselessly screen nitrogen oxide levels in your debilitate stream. They offer assistance guarantee your vehicle complies with Euro VI and EPA directions whereas keeping up ideal motor execution. Your outflow control framework depends on exact NOx estimation to work viably and ensure our environment.
Xi'an Qintai Car Outflow Innovation brings over 20 a long time of ability to each sensor we make. Our progressed outflow control arrangements serve major diesel motor producers over China and globally.
Lightning-Fast Response
Your motor needs moment criticism for ideal execution.Qintai sensors provide reaction times beneath 1400ms, guaranteeing your SCR framework responds rapidly to changing debilitate conditions.
Extended Service Life
Built to final up to 6000 hours, our sensors surpass industry measures. This implies less substitutions and lower upkeep costs for your fleet.
Quick Startup Technology
Qintai light-off time is essentially shorter than the industry standard of 165 seconds. Your emanation control framework gets to be dynamic quicker, decreasing cold-start emissions.
Advanced Poisoning Resistance
Diesel debilitate contains destructive contaminants. Qintai sensors stand up to lead and sulfide harming superior than ordinary options, keeping up exactness longer.

Your SCR aftertreatment framework depends on exact NOx estimation to work appropriately. Here's how our sensors bolster your emanation control:
Precise Dosing Control
The upstream sensor measures approaching NOx levels. Your motor control unit employments this information to calculate the correct sum of urea (AdBlue) required for ideal conversion.
Efficiency Monitoring
The downstream sensor confirms that your catalytic converter is working successfully. This guarantees most extreme NOx diminishment and anticipates catalyst harm from over-dosing.
Real-Time Diagnostics
Qintai NOx Sensors persistently screen framework execution. They distinguish flaws early and offer assistance anticipate exorbitant breakdowns.
Every application has one of a kind necessities. We offer adaptable customization to coordinate your particular needs:
