Product details

The Pentair SL1DW is an in-line thermometer with a 30 to 130 degree range. It plumbs into the circulation line so the reading comes from the water actually moving through the system.

Why in-line

A floating thermometer tells you what the surface of the pool is doing. A line mounted gauge tells you what the equipment is seeing, which matters when you are setting a heater, checking temperature rise, or trying to work out whether the pool is really as warm as the controller claims.

Details

The manufacturer part number is SL1DW. Beyond the range and the in-line mounting, the listing carries no further specifications.

Questions and answers

What people ask about this product, answered by our pool techs.

Where does this thermometer install?
In the plumbing line. It is an in-line thermometer, so it reads the circulating water at the equipment rather than sitting in the pool.
What range does it read?
It is listed as a 30/130 degree in-line thermometer.
Is it a genuine Pentair part?
Yes. The manufacturer part number is SL1DW.
Why use one of these instead of a floating thermometer?
A line mounted gauge stays put and reads the water moving through the equipment, which is what you want when you are checking how much a heater is actually adding.
