Sauna bathing members will benefit from the more reliable and repeatable sauna bath experience.

Handsomely engineered with progressive beveling and integral air slots, and solidly constructed of 18 gauge stainless steel, the RB 321 is designed protect the sauna heater thermostat sensor while inducing air movement and helping to keep unwanted water out.

Behind its sleek, low-profile exterior, the RB 321 employs an ABS plastic sensor mount designed to secure and isolate the sensor from contact with the stainless steel guard and wall materials while suspending it within the air-stream for more precise sauna room temperature readings. This isolation allows for enhanced sensor sensitivity, shorter sauna cycle times and a more consistent heat for bathers!

Measuring 5-1/8” wide and 2-3/8” tall, the RB 321 securely guards most any sauna room temperature sensor and ships complete with stainless steel fasteners and mounting template for a simple, near-permanent installation.

Consider the RB 311 Sauna Room Temperature Sensor Guard for applications where a smaller scale guard may be required.
