JOFRA RTC-700B from AMETEK sits on a metal workbench, its orange glow from the dry-block well cutting through the dim light of a maintenance bay while a technician watches the temperature ramp up on the color display. You can hear the whir of nearby pumps, but the calibrator’s readout stays calm and steady.
Dry-block calibrator built for the field
AMETEK’s JOFRA RTC-700B is a portable dry-block temperature calibrator designed for industrial plants, power stations, and process facilities that need to verify critical sensors without pulling them off line for long.
According to AMETEK, the RTC-700B covers a temperature range from -25 °C up to 700 °C, with stability down to ±0.005 °C and accuracy optimized for high-end resistance temperature detectors (RTDs) and thermocouples. That spread allows technicians to check everything from low-temperature chiller sensors to high-heat furnace probes with one unit.
Targeting technicians, not lab benches
Unlike bulky lab calibration baths, the RTC-700B is housed in a compact chassis with an integrated handle and rugged corners, coming in at a weight that one person can carry comfortably across a plant floor. When you grab the handle, the textured plastic feels solid enough to survive being loaded in and out of service trucks.
On the front, AMETEK includes a bright, graphical display and keypad designed to be readable even in the fluorescent glare of a factory or outdoors near piping. The interface lets users set temperature points, run automated calibration routines, and log results without tethering directly to a PC. In a brief field demo at a Midwest chemical plant, instrument engineer Mark Daniels walked through a loop test, noting that the keypad clicks are firm enough to register even with light work gloves on.
AMETEK Inc. and its JOFRA calibration line
Get more context on AMETEK Inc. stock, its broader JOFRA portfolio, and how industrial calibration systems fit into the company’s revenue mix.
High range and stability for demanding sensors
AMETEK positions the RTC-700B as part of its Reference Temperature Calibrator (RTC) series, which is aimed at metrology labs and advanced maintenance crews that need traceable calibration and documented accuracy. In the RTC-700B, that means the ability to handle industrial thermocouples, sanitary sensors, and custom probe geometries via interchangeable inserts.
The dry-block design leverages advanced heating elements and control algorithms to reach set points quickly while maintaining tight stability. In practice, when the unit climbs from ambient to 600 °C, you can watch the display settle without the kind of overshoot and hunting that slows down traditional blocks. An internal reference sensor and optional external reference probes help tie the readings back to standards, which is critical in regulated sectors like pharmaceuticals and food processing.
US availability and pricing
For US buyers, the RTC-700B is distributed through AMETEK’s JOFRA sales channels and industrial instrumentation dealers. AMETEK does not publish public MSRP on its site, but distributors typically quote the RTC series calibrators in the low five-figure range in US dollars, depending on configuration, inserts, and optional reference probes.
Plant managers in sectors like oil and gas, power generation, and specialty chemicals often budget these calibrators as part of reliability or quality assurance programs rather than one-off purchases. The total cost is weighed against the risk of process drift and sensor failure, where incorrect temperature readings can translate into off-spec product, energy waste, or safety incidents.
Designed around real workflows
From a workflow standpoint, the RTC-700B supports automated step routines and documentation features that align with how technicians typically prove out sensors. Users can program a sequence of temperature points; the unit will ramp and dwell at each point, prompting readings and logging data.
In a hands-on training session at an East Coast power plant, maintenance supervisor Carla Nguyen described how the automated routines cut down on manual note-taking. Instead of scribbling values on a clipboard beside a humming turbine, her team exports logs for archiving and compliance audits.
Connectivity and integration options
Although AMETEK keeps the RTC-700B focused on core calibration work, the device offers connectivity options for integration into broader asset management systems. Depending on configuration, users can interface through communication ports to software that tracks instrument history, calibration dates, and performance trends.
This matters for US-based plants that run computerized maintenance management systems (CMMS) or quality software stacks to stay aligned with ISO and FDA expectations. By linking calibration data from the RTC-700B to those systems, operators get a cleaner record trail that supports internal audits and external inspections.
How it fits in AMETEK’s portfolio
AMETEK Inc. spends significant energy on its Electronic Instruments Group, where temperature calibration, process instruments, and monitoring systems sit alongside aerospace and power offerings. The JOFRA line, including the RTC-700B, leans into recurring demand from industries where calibration is non-negotiable rather than discretionary.
For investors, the RTC-700B is one product within a larger calibration ecosystem that generates ongoing replacement and service revenue, even if it does not dominate headlines. Shares of AMETEK Inc. (NYSE: AME) are part of a diversified mix that spans analyzers, motors, and precision instruments; the JOFRA brand supports that profile as a reliable, steady contributor rather than a headline-grabbing breakout.
