Ⅰ、product description
The quantitative leak to infrared sensor at the core, high-precision
sampling AD, speed ARMCPU, making the sample data is more real, more
reliable. The instrument uses a color LCD touch-screen display, user-friendly
appearance, easy to operate.
At present, some service providers are still using electricity
electrochemical sensor principle of sulfur hexafluoride, SF6 sensors but this
can not meet the test of the power industry SF6 low range, such 0-50PPM,
there 0-3000PPM, but the infrared SF6 sensor principle can customize these
ranges
1the principle of infrared absorption (NDIR)
2dual-wavelength, with temperature compensation
3high reliability, with no cross-reactivity to other gases.
4compared with electrochemical sensors, sulfur hexafluoride sensor
infrared sensor up to 10 years of life
5cost-effective, affordable discounted prices.
6compared with electrochemical sensors, sensor eliminates sulfur
hexafluoride and maintenance costs
7no radiation, no harm
8micro structure, low power consumption
9the digital and analog outputs.

Ⅳ、Appearance introduction
The meter uses 4.3" TFT touch screen, which is easy and convenient to
use with more beautiful appearance. The meter adopts 32-bit ARM MCU,
which provides higher response speed and better measuring precision.
Ⅴ、Features
1. Boot interface
The system guidance interface is as shown in the following picture:

- 5 -
After the meter is powered on, a welcome interface will show on the meter.
You can touch any place on the touch screen to enter the “sensor calibration
interface”, or wait for 10 seconds and the system will automatically enter the
“sensor calibration interface”.
2. Sensor calibration interface
The sensor calibration interface is as shown in the following picture：
After entering the “sensor calibration interface”, you’ll see such touch
buttons as [curve], [history], [save], [system] and [print].
After several minutes, the system will automatically enter the
“measurement interface”.
3. Measurement interface

- 6 -
After entering the “measurement interface”, you’ll see such touch buttons
as [curve], [history], [save], [system] and [print]. Press the corresponding
buttons to enter “measurement curve”, “history data”, “save data”, “system
setting” and “print data”. Meanwhile,
The curve interface is shown as follows:
After entering the “measurement interface”, press [measure] to enter the
curve interface. You’ll see the sample curves corresponding to SF6 content
and current time. At the time, press [measure] to enter the measurement data
interface.
4. historical data
