Fieldpiece

Fieldpiece Instruments is a manufacturer of professional-grade test instruments and tools for HVACR technicians and service professionals. Founded in 1990 by Rey Harju, Fieldpiece built its reputation on the HS24 stick meter, the first modular diagnostic tool with swappable detachable heads that allowed a single meter to perform multiple test functions in the field. Fieldpiece has since expanded to a full line of more than 200 HVACR-specific products, including digital manifolds, vacuum pumps, recovery machines, leak detectors, combustion analyzers, clamp meters, and the wireless Job Link System. Fieldpiece instruments are designed exclusively for the HVACR trade and are developed in close collaboration with working technicians. Fieldpiece products support A2L refrigerant service where applicable, and the company operates training resources through Fieldpiece University for trade professionals.

Job Link System

The Job Link System is Fieldpiece's integrated wireless platform, connecting digital manifolds, probes, scales, and clamp meters to a central app interface for real-time system diagnostics. Job Link probes monitor temperature, pressure, humidity, and amperage simultaneously from a single display, reducing the number of individual instruments a technician needs to carry to complete a system checkout. Job Link System components communicate wirelessly, allowing the technician to position probes at multiple points in the system and read all data from a single device. The Job Link System is the platform that connects the SM382V and SM482V digital manifolds with temperature and humidity probes for automated superheat and subcooling calculations.

Digital Manifolds

Fieldpiece digital manifolds are available in three-port (SM382V) and four-port (SM482V) configurations and provide wireless connectivity for integration with the Job Link System. Digital manifolds from Fieldpiece display refrigerant pressure, temperature-compensated saturated temperature, superheat, and subcooling simultaneously, replacing the calculation steps required with analog gauge sets. The SM-series manifolds support a range of refrigerants including A2L-classified refrigerants where applicable. The three-port SM382V and four-port SM482V differ in connection configuration: the four-port model adds a utility port for simultaneous access to a vacuum pump and recovery machine, which can reduce the need to break connections between service steps.

Vacuum Pumps and Recovery Equipment

Fieldpiece vacuum pumps are engineered to reach the deep vacuum levels required for HVACR system evacuation before charging. Fieldpiece vacuum pumps are designed to work with the Job Link System, allowing vacuum level monitoring wirelessly through the platform. Fieldpiece recovery machines are designed specifically for HVACR refrigerant recovery, with models suited to residential, light commercial, and commercial service work. Where a standard vacuum pump requires the technician to manually monitor the micron gauge at the pump, the Fieldpiece wireless vacuum gauge and Job Link integration allow monitoring from anywhere in the work area.

Leak Detectors, Combustion Analyzers, and Diagnostic Instruments

Fieldpiece offers a complete line of electronic leak detectors, including the DRX3, DR82, and DR58 models, covering refrigerant leak detection for service and installation applications. Combustion analyzers from Fieldpiece measure flue gas composition, CO levels, and combustion efficiency for furnace and boiler service, with CO detectors for ambient monitoring also available. Additional Fieldpiece diagnostic instruments include digital manometers with pressure switch testing capability, anemometers and air flow meters for duct balancing, and psychrometers for temperature and humidity measurement. The full diagnostic instrument line is designed for trade professionals who service both refrigerant-based and combustion equipment.

Why Contractors Specify Fieldpiece

HVACR technicians specify Fieldpiece because the company designs and manufactures instruments exclusively for the HVACR trade, integrating feedback from working technicians into each product generation. The Job Link System wireless platform reduces instrument count and cable management in the field, allowing a single app interface to display data from multiple probes and manifolds simultaneously. Fieldpiece instruments support A2L refrigerant service where applicable, keeping technicians equipped for the current and near-term refrigerant transition. Founded in 1990, Fieldpiece has more than 35 years of HVACR instrument development experience, and the company offers structured training through Fieldpiece University. Fieldpiece instruments are sold through HVAC supply distributors including SupplyHouse across the full product range.

How to Choose a Fieldpiece Product

The primary selection variable for Fieldpiece instruments is the specific service function required. For refrigerant system diagnostics, the SM-series digital manifolds and Job Link System probes are the core platform. The three-port SM382V suits standard two-service-port systems; the four-port SM482V adds a utility port for simultaneous vacuum pump or recovery machine connection, reducing reconnection steps during a service call.

For system evacuation, select a Fieldpiece vacuum pump based on the system volume and the target micron level required by the equipment manufacturer. Residential and light commercial systems typically require pumps in the 6 to 8 CFM range; larger commercial systems may require higher-capacity models. For refrigerant recovery, match the Fieldpiece recovery machine to the refrigerant type in the system and the volume to be recovered.

For combustion equipment service, the Fieldpiece combustion analyzer is the appropriate instrument, providing flue gas analysis for furnace and boiler tune-up and efficiency verification. For duct balancing and airflow commissioning, the Fieldpiece anemometer and air flow meters provide the measurements needed. For refrigerant leak detection, match the Fieldpiece leak detector sensitivity to the refrigerant type in the system, as some refrigerants require higher-sensitivity detection than others.

FAQs

When was Fieldpiece Instruments founded and where is it based?

Fieldpiece Instruments was founded in 1990 by Rey Harju, who developed the company's first product, the HS24 stick meter with detachable heads, in his garage over three years of development. Fieldpiece operates in Southern California. The company has more than 35 years of HVACR instrument development experience.

What warranty does Fieldpiece offer on its instruments?

Fieldpiece warranty terms vary by product category. For specific warranty coverage on a Fieldpiece digital manifold, vacuum pump, or diagnostic instrument, consult the product documentation included with the instrument or the Fieldpiece website for the applicable warranty period and coverage terms.

What is the difference between the Fieldpiece SM382V and SM482V digital manifolds?

The difference between the Fieldpiece SM382V and SM482V digital manifolds is the number of service ports. The SM382V is a three-port manifold suited to standard two-service-port refrigerant systems. The SM482V is a four-port manifold that adds a utility port for simultaneous connection to a vacuum pump or recovery machine without breaking service connections between steps. Both models are wireless and compatible with the Fieldpiece Job Link System.

What size vacuum pump do I need for residential HVAC service?

For residential HVAC service, a Fieldpiece vacuum pump in the 6 to 8 CFM displacement range is typically appropriate for single-zone residential split systems. Larger commercial systems with greater refrigerant circuit volume may require higher-capacity pumps. Consult the equipment manufacturer's evacuation specification for the target micron level, and select a Fieldpiece pump capable of reaching that depth within a practical timeframe.

Are Fieldpiece instruments compatible with A2L refrigerants?

Fieldpiece instruments include models with A2L refrigerant compatibility where applicable. For specific A2L refrigerant support on a Fieldpiece digital manifold or vacuum pump, check the product specification sheet for the refrigerant list supported by that model. Fieldpiece actively updates product lines to support refrigerant transitions in the HVACR industry.

What is Fieldpiece University?

Fieldpiece University is Fieldpiece's structured training resource for HVACR technicians, offering instruction on how to use Fieldpiece instruments effectively in the field. Training is available through the Fieldpiece website. Fieldpiece University covers instrument operation, diagnostic techniques, and best practices for using the Job Link System and individual Fieldpiece tools in HVACR service work.
