Q: Are you a factory/manufacturer?
Q: What's the common power supply and signal output?
A: Common power supply and signal output is DC12-24V, RS485. But we can customize for you as demands.
Q: How can I collect data?
A: If you have your own data logger, you only need to buy our sensor and meanwhile we send you communication protocol.
Q: What's the lifetime of this air quality monitoring equipment?
A: At least 5 years long. Every sensor has its own calibration certificate or testing report.
Q:What's the delivery time?
A: Usually, we dispatch goods in 3-5 working days after receiving your payment. But it depends on your quantity.
Q: May I know your warranty?
A: Yes, usually it's 1 year. We can send you detailed warranty document if needed.
