Hand Held Instruments For HVAC/R Installation And Maintenence. Fieldpiece is the creator of the modular digital multimeters called Stick Meters.
Fieldpiece Instruments – HVAC-R Maintenence
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.
Get the true voltage and amperage when testing variable speed fans or other non-sine wave applications.
- Microamps – For flame rectifier diode tests.
- Capacitance – For motor-run and motor-start capacitors.
- Frequency – For variable frequency drives.
- Temperature – Thermocouple plugs in directly
Rugged rubberized case with magnetic hanger. Hi-voltage indicators you can’t miss–both LED and beeper. Continuity indicated by LED and beeper.
