Series I2-1 Immersion Temperature Probe

Brand: Dwyer Instruments, LLC

The Series I2-1 Immersion Temperature Probes are designed to monitor the hot and chilled water lines throughout a building's water distribution loop.

The multiple temperature sensor outputs allow these sensors to connect to virtually any digital building controller. 

The Series IW2 stainless steel thermowells allow the temperature sensors to be replaced without draining the water line.

The temperature sensors are available in 4" and 6" insertion lengths.

Note: A Series IW2 Thermowell must be used on pressurized air and water lines to prevent leakage around the probe.
