Taylor 9878E Dual Input Digital Thermometer 500F

Product Description

The TAYLOR 9878E is a dual input digital thermometer designed for professionals who need accurate temperature readings across two measurement points simultaneously. It features an LCD display for clear readout and supports a maximum temperature of 500 degrees F, making it suitable for HVAC diagnostics, refrigeration work, and other trade applications where monitoring supply and return temperatures or comparing two zones is part of the workflow. The unit is compact and handheld, powered by a 1.5-volt battery, and is intended for use by HVAC technicians, plumbers, and facilities maintenance personnel.

This thermometer is well suited for residential and light commercial service work. Common applications include measuring supply and return air temperatures across a heat exchanger, verifying delta-T across a coil, checking radiant floor zones, or monitoring dual-zone process temperatures. Its dual input capability allows a technician to read two probe channels at once, reducing the need to swap probes during a service call.
