Features of the extractive ZrO2 analyser

Specifications of the extractive ZrO2 analyser

Redefined precision

The exceptional repeatability of this analyser gas meter is impressive, with a tolerance of ± 0.5% of full scale. Linearity, a crucial feature for accurate measurement, is maintained at ± 1% of full scale.

Operational stability

Zero drift is limited to ± 1% of full scale per week, ensuring continuous operational stability. In addition, scale drift is maintained at ± 2% of full scale per week.

Instant reactivity

With a response time of around 20 seconds to reach 90% of response, this analyser ensures instantaneous responsiveness, optimizing the performance of industrial processes.

Optimal Sampling Rate

The precise sampling rate of 0.5 ± 0.25 L/min enables meticulous measurement, ensuring effective control.

Versatile design

The analysers ZrO2 gas meters feature Rc% or NPT% inlet/outlet connections for extensive compatibility with various systems. The steel housing, suitable for indoor use, guarantees robust protection.

Food Management

With a voltage range of 100 to 115 Vac or 200 to 240 Vac and a frequency of 50 Hz/60 Hz, the analyser offers flexible power management. Maximum power rating is 215 VA at start-up and 65 VA during normal operation.

Intuitive display

The user interface is simplified with LED indication, ensuring easy monitoring.

Integrated alarm output

The alarm output, with a contact capacity of 220 Vac, 1 A (resistive load) on contact A, reinforces the safety function.

Compact and lightweight

With external dimensions of 141 (W) x 170 (H) x 190 (D) mm and a weight of around 3 kg, these analysers offer a compact solution without compromising on performance.
