Endura pH – TBX587 “T” handle & Pressure Rating Tough made easySM “T” Handle allows for easier insertion and retraction by the operator Faster removal and insertion Easier maintenance Safer operation The TBX587 Sensor has a 150 PSIG (10 BAR) pressure rating Longer lasting More applications © ABB Group April 23, 2017 | Slide 9

Endura pH – TBX587 Vario Pin Quick Disconnect Tough made easySM “Vario Pin” provides a quick, easy, way to change out sensors. Vario Pin is IP68 Water tight No junction box required Saves time and money! (Traditional wire leads also available) © ABB Group April 23, 2017 | Slide 10

Endura pH – TBX587 Simple Ordering Tough made easySM Flexible ordering options “Specials” such as Titanium, Hastelloy, or Kalrez incorporated into model number Simplified cable lengths Less reference options © ABB Group April 23, 2017 | Slide 11

Endura pH – TBX587 Petroleum Refining Applications Tough made easySM Crude Distillation Water Water condensed from steam in distillation will have organics and be acidic – TBX587 resistance to plugging ideal for this application Scrubbers Sour gas must be treated which is high in sulfides – TBX587 resistance to chemical poisoning ideal for this application Waste Water Residual oils and organics must be treated throughout the plant – TBX587 resistance to plugging & poisoning ideal for these applications © ABB Group April 23, 2017 | Slide 12

Endura pH – TBX587 Power Generation Scrubber Applications Tough made easySM TBX587 with wood reference and flat glass electrode resists abrasive gypsum slurry from absorber. Tee handle allows for easy insertion and retraction if process build-up is problematic. Flushing ports can be used in extreme slurry applications to purge the sensor prior to insertion and extraction. Babcock & Wilcox FGD Scrubber Shown © ABB Group April 23, 2017 | Slide 13

Endura pH – TBX587 Pulp & Paper Mill - Pulping and Bleach Applications Tough made easySM Direct replacement for other products that use a 1” NPT (25mm) process connection. Teflon Next Step Reference provides extremely long life when exposed to pulping and bleaching chemicals. Sensor lifespan normally 2x to 3x that of conventional gel filled sensors.
