AIR GAS CONCENTRATION METER WINTACT WT8811 - AIR COMPOSITION MEASUREMENT

Multifunctional gas content meter. The device employs high-quality sensors characterized by precise measurements, reliability, and stability. The meter features excellent sensitivity and repeatability, is easy to operate and maintain, and meets security monitoring requirements in industrial facilities. The casing is made from durable materials and rubberized remnants, offering effective protection against dust and drops, as well as reducing the risk of self-ignition in cases of high concentrations of flammable gases.

APPLICATION: The meter is widely used in the oil industry, chemical industry, environmental protection, metallurgy, refining, gas transportation and distribution, biochemical medicine, agricultural research, and more.

KEY FEATURES AND FUNCTIONS OF THE DEVICE:

• Color display and user-friendly interface.
• Measurement of content and concentration for: oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO), flammable gases (LEL).
• Three alarm types: audible, visual, and vibration.
• Data logging and review, continuously up to 120,000 records.
• Device battery charging function.

• Operating voltage: DC 3.7V (lithium battery with a capacity of 1800 mAh).
• Charging time: 6~8h.
• Battery operation time: approximately 8 hours of continuous operation (depending on conditions and usage).
• Dimensions: 71 x 153 x 49 mm.
• Weight: 218.7 g (including battery).

The device meets the following calibration procedures and standards: GB3836.1—2010, GB3836.4—2010, GB15322.3—2003, JJG693—2011, JJG 365 — 2008, JJG695-2003, JJG915-2008, which pertain to safety specifications for the use of portable devices in atmospheres with high concentrations of flammable gases.

MENU PROCEDURE: From the main menu, one can start individual or multiple simultaneous measurement functions, access data review, enter alarm limit settings, activate settings, and enter calibration mode (for advanced users only).

MULTIPLE MEASUREMENT PROCEDURE: The interface displays real-time values of four elements simultaneously. When a value exceeds the range, the number will start to blink. If the alarm is activated, an alarm will be triggered.

SINGLE MEASUREMENT PROCEDURE: The interface for this function presents a selected value. On the left, the displayed values are: maximum, minimum, and average, with the latter including the average readings from the last 4 minutes.
