The truly unique aspect of the STs Series is that every part, including the cable, is easily replaceable in the event of wear\/damage. This considerably extends their lifespan to save your company money. It also keeps waste out of landfills to support sustainable business practices.\u003c\/p\u003e\n\u003ch3\u003eGround Loop Elimination\u003c\/h3\u003e\n\u003cp\u003eIf you ever have a pH sensor sending erratic measurements and can’t figure out why, then there may be a “ground loop”. A ground loop occurs when the electrical circuit has multiple paths to ground that cause interference. This issue can be very difficult to detect and fix. The best way to avoid ground loops is with input\/output electrical isolation, which is built into every pHionics sensor.\u003c\/p\u003e\n\u003ch3\u003eLow Maintenance\u003c\/h3\u003e\n\u003cp\u003eVery little is required to keep these sensors up. Just perform periodic calibrations and replace the electrode every few years. Electrode replacement is a 60-second procedure that is easily performed in the field without any tools.\u003c\/p\u003e","brand":"pHionics","offers":[{"title":"Default Title","offer_id":54234934739291,"sku":"SSPH-Sensor","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0976\/0302\/7291\/files\/phionics_sts_series_ph_water_quality_sensor.jpg?v=1790932828","url":"https:\/\/www.tempcon.co.uk\/products\/sts-series-ph-sensor","provider":"Tempcon Instrumentation","version":"1.0","type":"link"}
