Q1. Can it applied to other gases?
A: KQ500D series can detect a wide range of gases, but one device is designed for one gas.
Q2. What is your minium order?
A: Sample order of 1 set for checking quality is welcome
Q3. What about the lead time?
A: We usually deliver the goods in 2-5 working days after the order confirmed.
Q4. How is the calibration been done?
A: To keep the high sensitivity, please calibrate it at least once a year .
Q5. Is it OK to print my logo on the gas detector?
A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.
