Honeywell 00888A3 Digital Indoor Outdoor Thermometer

Product Description

The HONEYWELL 00888A3 is a dual-display digital thermometer designed to monitor both indoor and outdoor temperatures from a single unit. The device reads temperatures across a wide dual range of -58 degrees F to 158 degrees F (-50 degrees C to 66 degrees C), making it suitable for a broad range of service environments. A 10-foot submersible weatherproof probe handles the outdoor or remote sensor duties, while the backlit digital display shows current readings along with minimum and maximum memory values. The compact housing measures 2.75 inches wide by 3.125 inches high by 0.375 inches deep and is constructed from plastic. Batteries are included. HVAC technicians, plumbers, and facility maintenance professionals use this type of instrument for temperature verification during system commissioning, service calls, and equipment diagnostics.

The 00888A3 is suited for residential and light commercial applications where a quick, reliable temperature reference is needed at the job site or in a mechanical room. The folding table stand allows the unit to be placed on a surface for hands-free monitoring, while the wall-mount option provides a fixed installation point. The submersible weatherproof probe can be routed to an outdoor location, an equipment compartment, or a fluid environment to capture remote temperature readings without exposing the main display unit to harsh conditions.

Installation Notes

No special tools or trade licensing are required to deploy this thermometer. Route the 10-foot weatherproof probe to the desired sensing location before securing the display unit to a wall or setting it on a flat surface. When mounting on a wall, ensure fasteners are appropriate for the surface material. Keep the main display unit away from direct moisture exposure even though the probe is rated submersible.
