While the ZEUS™ pH Sensors are only available in the configurations as detailed above, all other IOTRON™ series pH sensors can be custom built-to-order specific to your exact application requirements. Please review our pH sensor overview webpage to select the customizable product line that is most suitable for your need if you prefer this option. All other IOTRON™ series pH sensors are not in stock since they are built-to-order to suit specific requirements. Lead times are normally relatively nominal since most all necessary components are well stocked for most combinations and the availability is only limited by actual manufacturing time, processing of the order and time in the production queue.
