Boiler Conductivity Sensors

Custom Manufactured, Proven Performance.
Lakewood Instruments boiler conductivity sensor

It’s more than an oversized spark plug. Boiler conductivity sensors do the dirty work, day and night in hot, high-pressure conditions! This is where over 45 years of manufacturing reliable cost-effective boiler sensors comes in.

Lakewood’s sensor design is clean, crisp, and works right every time. We have just the right boiler conductivity sensors for your boiler.

  • SR Sensor, no temperature compensation needed, 500-10,000 micro siemens, rated to 600 psi at 486F.
    • 1167162 – sensor only
    • 1168374 – sensor, conduit elbow, 20′ cable
  • HD SR Sensors, just like the SR but for harsh duty environments, typically higher levels of amines:
    • 1229841 – HD sensor only
    • 1229843 – HD sensor, conduit elbow, 20′ cable
  • SR4, 4 electrode sensor for use with a sample cooler.
    • 1168375 – SR4, 20′ cable

The SR and HD sensors work great with the full line of Lakewood Controllers, including the new Model 3175, which is awesome for tracking boiler conductivity over time. Need a signal transmitter, electronic node, or related fixtures? We’ve got those too, just give us a call.
