KSCH4 Methane sensor manual
Introduction
KSCH4 is a based on NDIR non-dispersed infrared absorption principle of gas detection module, adopt the dispersive air inlet. KSCH4 using porous inner light tube and casing outside the card slot, not only ensure the characteristics of air convection diffusion speed, and strong and durable, easy to install.
KSCH4 uses an imported light source and a dual-channel detector. Has the very good selectivity, no oxygen dependence, long life characteristics.
KSCH4 with UART, IIC digital output and analog output voltage (or the PWM frequency output mode), facilitating the clients to choose application; KSCH4 provide zero calibration, calibration and sensitivity of clean air relative zero calibration command, and to provide customers a manual clean air relative zero calibration MCDL pin, convenient to customers in the use of the free flow of clean outdoor air relative zero calibration of sensor module.

Precautions
Question 1
How can I get the proper product?
Answer,
It's better if you can supply us the parameters, such as the power supply you request, the measure range you need.
the output signal you need,
also if you are not familiar with the parameters above ,you can supply us the application field information.
what kind product you used before.
Question 2
What about the warranty?
Answer,
The normal warranty is 12 months.
Question 3
We want samples first, do you support?
Answer,
Yes, we support samples. It's better for both sides.
