The CL900 Electrical Tester is an auto-ranging, true root mean square (TRMS) digital clamp meter. It measures AC/DC current via the clamp and measures AC/DC voltage, resistance, continuity, frequency, duty-cycle, capacitance, and tests diodes via test-leads. It features a Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages, and has a dedicated mode for capturing Inrush Current.

Klein Tools ET05 is a digital thermometer that takes ambient and direct-contact readings in both Fahrenheit (°F) and Celsius (°C) scales. The rugged, portable design makes it the choice of HVAC field service teams. The protective sheath cleverly serves as a handle to extend reach.

The ET110 CO Detector is an easy-to-use meter that detects and measures concentration levels of carbon monoxide (ppm) and temperature (Fahrenheit/Celsius), making it the perfect choice for HVAC professionals. Features backlit LCD screen, warning indicator light, audible and visual alarms and multiple function buttons. Includes carrying pouch and 4 x AAA batteries.
