Main product models and technical parameters

Oxygen analyzer (EasyLine O ₂)

Measurement principle: Based on oxygen paramagnetism, using magneto mechanical principle, with short response time.

Measurement range: The minimum measurement range is O ₂ 0-2 Vol. -%, supporting a suppression measurement range with a minimum span of 2 Vol. -% O ₂.

Stability: Linear deviation ≤ 0.5% of span, repeatability ≤ 0.5% of span, zero drift ≤ 0.03 Vol. -% O ₂/week, sensitivity drift ≤ 0.1 Vol. -% O ₂/week or ≤ 1% measurement value/week (whichever is smaller, not cumulative).

Dynamic response: T ₉₀ time ≤ 5 seconds.

Installation environment: ambient temperature+5...+50 ° C.

Equipment specifications: Adopting a 1/2 19 inch casing, supporting desktop and rack installation, with dimensions of approximately 215 x 167 x 347 mm (width x height x depth) and a weight of approximately 8 kg.

Interface and connection: 1 channel 4-20 mA analog output (maximum 750 Ω), 2 channels of alarm value signal and 1 channel of collective status signal digital output, supporting RS-485 or RS-232 interface (configurable).

Gas connection: The inlet and outlet ports are equipped with DN 4/6 hoses.

Power supply: Input voltage 85-250 VAC, 48-63 Hz, maximum power consumption 90 VA.

Infrared gas analyzer (EasyLine IR)

Measurement principle: Infrared photometer can measure 1 or 2 components. If used in conjunction with an electrochemical oxygen sensor, it can only measure 1 infrared gas component.

Measurement range: The measurable gases and minimum measurement range include CO 0... 500 ppm, CO ₂ 0... 500 ppm, SO ₂ 0... 500 ppm, CH ₄ 0... 500 ppm, NO 0... 1000 ppm. It can also be combined with O ₂ (0... 5 vol. -%) for measurement (specific combinations are shown in the document table).

Stability: Linear deviation ≤ 1% of span, repeatability ≤ 0.5% of span, zero drift ≤ 1% of span/week, sensitivity drift ≤ 1% of measured value/week.

Dynamic response: T ₉₀ time ≤ 2 seconds (O ₂ sensor ≤ 30 seconds).

Installation environment: ambient temperature+5 to+45 ° C (+5 to+40 ° C with O ₂ sensor).

Equipment specifications: Same as oxygen analyzer, 1/2 19 inch casing, size approximately 215 x 167 x 347 mm, weight approximately 8 kg.

Interface and Connection: Each sample component has 1 analog output and 2 digital outputs of alarm value signals, supporting RS-485 or RS-232 interfaces (configurable).

Gas connection: The inlet and outlet ports are equipped with DN 4/6 hoses.

Power supply: Input voltage 85-250 VAC, 48-63 Hz, maximum power consumption of 40 VA.

Thermal conductivity gas analyzer (EasyLine TC)

Measurement principle: Based on the difference in thermal conductivity of different gases, micro mechanical thermal conductivity analysis technology is used, which has a short response time and is less affected by temperature.

Measurement range: It can measure various gas combinations and the minimum measurement range, such as CO ₂ in N ₂ 0... 10 Vol. -%, CH ₄ in N ₂ 0... 6 Vol. -%, etc. (see document table for details), supporting suppression of measurement range.

Stability: Linear deviation ≤ 2% of span, repeatability ≤ 1% of span, zero drift ≤ 2% of minimum given measurement range/week, sensitivity drift ≤ 0.5% of minimum given measurement range/week.

Dynamic response: T ₉₀ time ≤ 2 seconds.

Installation environment: ambient temperature+5...+50 ° C.

Equipment specifications: Same as the two analyzers mentioned above, with a 1/2 19 inch casing, dimensions of approximately 215 x 167 x 347 mm, and a weight of approximately 8 kg.

Interface and connection: 1 channel 4-20 mA analog output (maximum 750 Ω), 2 channels of alarm value signal and 1 channel of collective status signal digital output, supporting RS-485 or RS-232 interface (configurable).
