Fieldpiece HS36 Expandable Autoranging True RMS Stick Multimeter

Fieldpiece makes tools and test equipment specifically designed for HVAC technician. The Fieldpiece manufactured HS36 is a True RMS Stick Meter.  The HS 36 is a digital multimeter that has several features specific to the HVAC technician to make his job easier faster safer and better.Multimeter HVAC


Fieldpiece incorporates a number of safety features, both those you can and can’t see, into our meters. In addition, the HS series accepts modular test instrument accessory heads.

  • Three LEDs

o High voltage LED that will beep and light up when you are testing high voltage.

o Non-contact voltage LED that will beep and light up when you are using the       non-contact voltage feature.

o Continuity LED that will beep and light up when you are testing for continuity.

  • Three Buttons on the meter.

o     The bright blue blue backlight that lights up the screen so you can see in dark spots.

o     The non-contact voltage button that you press, hold, and put the tip next to something that you suspect is hot to see if it is hot or not.

o     The maximum button that will hold the max and min reading of whatever you are measuring.

  • The Dial

o     Continuity so we test continuity.

o     Volts/ DC. This is an auto-ranging meter so we’ll select the range for you and it is true RMS.

o     Microfarad’s for testing start run capacitors.

o     Temperature Sensor. The nice thing about the temperature is it’s with the k-type thermocouple it plugs in right into the front and it’s a very fast reacting sensor so when you are going from a hot roof down to a cold room it does not take very long to stabilize.

o     Micro amps DC pour when you are  testing fling diodes

o     Ohms for testing resistance

o     Hertz for testing frequency and we have your

o     Volts AC

  • The length of the leads is designed so they can be wrapped and stored right on your meter to better organize your meter when you are not using them.
