You can find more Questions and Answers from our Website Support section, here are some extracts:

What is the difference between Remote Reader and Computer Log version Reader?
A: Both reader consist of two USB devices, one is gas reader and transmitter, another function as data receiver. 
Both can collect data simultaneously and remotely!  Remote reader can pick up data outside gas room with 
another USB powered display so no computer needed on site (suitable for field work). Computer Log Reader 
can Read and Record data on Computer, you can save it in Excel format and use the data for later analysis or demonstration purpose.

How to read the figure on USB Gas Reader?
A: Firstly reader decimal point positions various depends on sensor detection range. For 0-100ppm reader, as its maximum range 
is 100ppm, resolution is 0.1ppm, so when it displays 009.3, it means 9.3ppm. If it displays 0.251, gas concentration is 
25.1ppm. (Easiest way is just read last 3 digits and ignore first digit). For 0-10ppm reader, if reader displays 8.400, it means
gas concentration is 8.4ppm. (Easiest way is read first 2 digits and ignores last 2). 

Do you have All in One reader which can read different gas and display in one device?
A: Yes we have, and we can design and produce a device that can read various gases and display all data in one device. Please contact us with 
your request and gas type; we will quote you within 24 hours.

How far is Bluetooth Allowed Remote Distance?
A: Technically 10 meters. But this varies depends on the quality of wall / house and whether there is disruptions. Reading 
between one wall should be no problem. We soldered Bluetooth modules on both USB devices so please face two modules with 
each other and minimize anything in between to get better signal. 
Our Bluetooth module connects automatically so no manual setting needed.

Can you provide invoice?
A: Yes we can provide commercial invoice and Pro-forma upon request.
