Fieldpiece Instruments makes a high quality HVAC test equipment. Fieldpiece hand held testing instruments have been designed to be functional and useful testers for all HVAC technicians.
In my last installment I wrote about the Fieldpiece HS36 Stick Meter. 
This meter accepts the accessory heads that Fieldpiece makes to expand its meters to fit its customer’s specific needs. The ACM3 CO Detector Head (pictured at right) is a snap-on Accessory that adds the capability of measuring CO to your Fieldpiece Stick Meter.
When we last left off, I gave a small introduction to Fieldpiece and
their philosophy regarding Multimeters in the HVAC world. Today we are going to discuss their HS36 TRMS Stick Meter. The Fieldpiece HS36 TRMS Stick Multimeter represents the top of the line Stick meter that Fieldpiece currently offers. For those unfamiliar with Stick style meters, this post should be a great introduction.
Fieldpiece Instruments is a California based manufacturer
that produces professional-grade testing equipment with a specialty in the HVAC/R market. While most Multimeters are designed for laboratory work or for use by electricians, Fieldpiece wanted to create a meter that was specifically designed with HVAC technicians in mind. What they came up with was the Stick Digital Multimeter.
The Fieldpiece SMAN3 model has been discontinued.
