A, the difference
1, ammonia sensor: ammonia sensor includes three principles of electrochemical ammonia sensor, infrared ammonia sensor, semiconductor ammonia sensor. It is just a major component of the ammonia detector. Now the most used on the market is the electrochemical, are the British CT's do the best. Of course, the good stuff is expensive, there are other manufacturers. Such as the British E2V, the U.S. Huarui and so on.
2, ammonia detector: ammonia detector is the detection of ammonia gas concentration of a series of products in general. Including: handheld ammonia detector, fixed ammonia detector, ammonia alarm, ammonia analyzer, wall-mounted ammonia detector, ammonia transmitter, ammonia probe, etc.
3, ammonia transmitter: said above, the ammonia transmitter is a branch of the ammonia detector. Can also be called fixed ammonia detector. With display and without display points. Many laymen call the transmitter as a sensor. In fact, it is wrong. Here will not say more.
4, ammonia alarm: ammonia alarm is based on the ammonia transmitter plus a sound and light alarm. More than one alarm function. The other functions are pretty much the same. It is also a branch of the ammonia detector.
Two, recommended some of the basic parameters of the ammonia detector and the use of the environment:
1, fixed ammonia detector (ammonia transmitter, ammonia alarm)
Fixed ammonia detector with a large LCD display with ultra-bright backlight easy to read, infrared wireless remote control is convenient and safe to operate, a variety of signal output, with temperature detection and temperature compensation. Ammonia detector is now used in the most environment is the farms and chemical plants.
