A polymer optical fiber is attached to the Sensor Stick and connects it to a pH meter. This way continuous, non-invasive pH measurements can be performed. The pH Sensor Stick can easily be integrated in customer specific flow-through cells or experimental set-ups via Luer connectors. The SST-HP5-US is independent of flow velocity or electromagnetic fields and due to its small size it can be implemented in many set-ups where other pH measurement equipment simply does not fit.<\/p>\n<table class=\"contenttable\">\n<tbody>\n<tr>\n<td>Measurement range<\/td>\n<td>pH 5.5 &#8211; 8.5<\/td>\n<\/tr>\n<tr>\n<td>Resolution<\/td>\n<td>at pH = 7: \u00b1 0.02 pH<\/td>\n<\/tr>\n<tr>\n<td>Accuracy**<\/td>\n<td>at pH = 7: \u00b1 0.05 pH<\/td>\n<\/tr>\n<tr>\n<td>Drift<\/td>\n<td>at pH = 7: &lt; 0.005 pH per day (sampling interval of 1 min.)<\/td>\n<\/tr>\n<tr>\n<td>Measurement temperature range<\/td>\n<td>From + 5 \u00b0C to + 50 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Response time (t<sub>90<\/sub>)***<\/td>\n<td>&lt; 120 sec.<\/td>\n<\/tr>\n<tr class=\"row-highlight\">\n<td colspan=\"2\" rowspan=\"1\">Properties<\/td>\n<\/tr>\n<tr>\n<td>Compatibility<\/td>\n<td>Aqueous solutions, ethanol (max. 10 % v\/v), methanol (max. 10 % v\/v), pH 2 &#8211; 10<\/td>\n<\/tr>\n<tr>\n<td>Cross sensitivity<\/td>\n<td>Reduced to ionic strength (salinity); a high concentration of small fluorescent molecules in the visible range can interfere<\/td>\n<\/tr>\n<tr>\n<td>Sterilization procedures****<\/td>\n<td>Irradiation, Ethylene oxide (EtO)<\/td>\n<\/tr>\n<tr>\n<td>Calibration<\/td>\n<td>SSTs are pre-calibrated; single-point adjustment is recommended<\/td>\n<\/tr>\n<tr>\n<td>Storage stability<\/td>\n<td>18 months provided the sensor is stored in the dark<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>*provided the pH Sensor Stick is used without further handling in physiological solution<br \/>\n**after single-point calibration at pH = 7<br \/>\n***equilibrated Sensor Stick with physiological solution and sufficient flow rate (min. 15 mL\/min) at 37 \u00b0C)<br \/>\n****recalibration may be required<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"VIiyi\" lang=\"en\"><span class=\"JLqJ4b ChMk0b\" data-language-for-alternatives=\"en\" data-language-to-translate-into=\"fr\" data-phrase-index=\"0\">Non-invasive pH measurement 5.5\u00a0 to 8.5<\/span><\/span><\/p>\n","protected":false},"featured_media":22517,"template":"","meta":{"_crdt_document":""},"product_brand":[],"product_cat":[179,239],"product_tag":[],"class_list":{"0":"post-22515","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-measurement","7":"product_cat-ph-en","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>pH sensor with Luer Lock SST-HP5-US - Sysmatec<\/title>\n<meta name=\"description\" content=\"Fiber optic pH sensor and Luer Lock connector.
