Our Goal

Heating is colloquially considered a luxury, and more in a country like Mexico, where the heat is taken as a daily. But when it comes to specialized industrial processes or performance and production in greenhouses, heating is not a luxury, it is an absolute necessity.

And as part of an industrial process, not a question that can be left to chance, is a matter of vital importance that may mean increasing the profit margin of a company, or total loss of investment in it.

Understanding this fundamental need, in Van Triest Engineering Group works to give the customer not only products of the best brands with proven quality, but also the necessary technical support for users who decide not see your confidence in your investment risk.

The mission of Van Triest Engineering is to provide the best product, best support and better care.

The combination-probe KS1D-HT is qualified for measuring at places or spots, which are marked by infiltrated air, as well as in multi-burner applications, for which a sole O2 measuring cannot give any statements for atmosphere or combustion process respectively a fast response is needed. It is used in applications controlling oven atmosphere at measureing gas temperatures up to 1400 °C.

It is applied to gas combustions of all types, wood- and carbon-dust combustions as well as garbage combustion plants, glow- and melting ovens and crematoriums.

Technical Data

Range of measuring O2:

0...21% O2
COe: 0...1.000 ppm COe, 0...10.000 ppm COe on request

Preciseness of measuring:

O2: +-5% of measuring value – not better than +- 0,3 Vol.%
COe: +-25% of measuring value – not better than +- 20 ppm
after prior alignment of application conditions with a CO reference measuring in a range of measuring 0...100 ppm: <= 10 ppm

Response time t60:
(60% of final value)

O2 <= 3 seconds
COe <= 9 seconds (unfiltered < 3 s)

Failure impact:

Change of temperature of measuring gas in dependency of preciseness of temperature control of ZrO2 measuring cell

Cross-sensitivity:

O2: to CO2 (15 vol. %) < 0.1 vol. % O2: to CO (874 ppm) < 0.1 vol. % O2: to CH4 (76 ppm) < 0.1 vol. % O2: to SO2 (76 ppm) < 0.1 vol. % O2: to NO (245 ppm) < 0.1 vol. % COe: to CO2 (15 vol. %) < 26 ppm COe: to O2 (1 vol. %) < 38 ppm
