5207 Replacement Tip 316 SS |
5205 Replacement Tip CPVC |
Lakewood Instruments uses the latest technology in pH electrode construction. Lakewood’s differential electrode design prevents ground loop problems and excessive dependence on the reference electrode connection to the process stream for stable readings. With two different body materials, three mounting options and three different glass electrodes, Lakewood Instruments can supply pH sensors to fit your needs.

-STD is the STANDARD glass bulb type electrode for use in systems with low fouling potential and minimal abrasives. pH range is 0-12, Max Temperature† is 230°F (110°C)† For replacement tips specify electrode type and total length in inches |
|
|
-HS is the HIGH SODIUM glass bulb type electrode for use in systems with a high pH and high concentration of sodium ions. This sensor compensates for sodium ion errors. pH range is 0-14, Max Temperature† is 212°F (100°C)† For replacement tips specify electrode type and total length in inches |
|
|
-DG is the extra strength DOME glass bulb type electrode for use in systems with slightly fouling or slightly abrasive water. pH range is 0-12, Max Temperature† is 212°F (100°C)† For replacement tips specify electrode type and total length in inches |
TEMPERATURE COMPENSATOR: 10K PTC
† Temperature rating of sensors depends on the combination of the body and glass electrode. Use the lower temperature of the sensor’s body or glass electrode to determine sensors temperature specification.
* The maximum pressure rating for the 5I, 5R, 7I and 7R options with the teflon ferrules is 70 psi.
