General PT300M Dual Input Digital Thermometer 302F

Product Description

The GENERAL PT300M is a dual-input digital thermometer designed for field measurement of temperature across HVAC, refrigeration, and mechanical systems. It accepts stainless steel probe sensors and displays readings on a built-in LCD screen. The unit spans a measurement range from -50 degrees C to 302 degrees F, covering both low-temperature refrigeration work and high-temperature HVAC applications. Battery-powered operation makes it suitable for portable field use. The plastic and stainless steel construction keeps the unit lightweight at 0.28 pounds. Licensed technicians and service professionals use this meter for system diagnostics, commissioning, and preventive maintenance checks.

The PT300M is suited for residential and light commercial applications where quick, accurate temperature readings are needed at multiple points. Typical scenarios include checking supply and return air temperatures, monitoring refrigerant line temperatures, verifying heat exchanger performance, and inspecting hydronic system temperatures. With dual input capability, a technician can read two probe locations simultaneously, reducing measurement time during system checks and troubleshooting calls.

Key Features

• Dual sensor inputs allow simultaneous temperature reading at two points
• LCD display provides clear readout in the field without backlight dependency
• Stainless steel probe sensor withstands repeated use in harsh mechanical environments
• Wide measurement range: -50 degrees C minimum to 302 degrees F maximum
• Battery-powered operation for fully portable, cord-free field use
• Lightweight at 0.28 pounds for easy carry in a tool pouch or bag

Compatibility

Designed as a portable diagnostic instrument compatible with standard stainless steel probe sensors for general HVAC, refrigeration, and mechanical temperature measurement applications.

Installation Notes

HVAC technicians and refrigeration mechanics typically deploy this thermometer during system commissioning, diagnostics, and maintenance. Before inserting probes into pressurized or energized systems, power down relevant equipment per standard lockout/tagout procedures. Ensure probe sensors are fully seated and secure before recording readings. Replace batteries as indicated to maintain measurement accuracy.
