Hand Held Instruments For HVAC/R Installation And Maintenence.
Fieldpiece Instruments – HVAC-R Maintenence
Fieldpiece is the creator of the modular digital multimeter. The “stick” style digital multimeter (DMM) combined with accessory heads make it easy to make electrical readings in the field and enables the technician to easily test a wide range of other parameters.
Highlights of Types of Stick Meters
Below is the HS36 – True RMS with Backlight.It includes the ranges you use everyday for HVACR field service plus includes a bright blue backlight and True RMS. Like the rest of the HS30 series, the HS36 comes equipped with a magnetic hanger,
Loud beeper and bright LED indicate the NCV tab is near AC voltages down to 24VAC.
