QUESTTEC QTLT-PR871-CRZG

Direct Replacement Electrode

The Questtec Solutions QTLT-PR871-CRZG is a copy of the Clark Reliance RZG020RK

The Clark Reliance RZG020RK probe is a zirconia insulator based probe used in their EL1800 water column. It uses gaskets and compression to form the seal between the metal and the zirconia. Drumline would never recommend this type of design for reliability reasons. The stated maximum rating is 1800 psi (124 bar) @ 438 degrees C (821 F).

Drumline recommend the use of it's DLRZG020RK as an upgrade for the Clark Reliance Probe. The DLRZG020RK is a brazed Zirconia probe that uses a spiral wound stainless steel and graphite gasket, instead of the cheaper gaskets used by Clark Reliance.

The DLRZG020RK is a direct upgrade for both the Clark Reliance RZG020RK and the RZ020BRZRK. Clark Reliance probes are extremely expensive at nearly $800 each and $25 for gaskets. Drumline can offer a better product at a much more realistic price.
