T-VAL Remote Head Calibrator

Experience unmatched precision in the field with the EDL TVAL Remote Head Drywell Calibrator—the ultimate solution for calibrating immersion and insertion sensors in the most challenging environments. Designed with portability and ruggedness at its core, the T-VAL enables technicians to perform in situ calibrations quickly and efficiently, eliminating the need to remove or disconnect sensor cables and harnesses. Its compact design, coupled with a generous 20-foot remote cable, makes it an indispensable tool for calibrating deeply embedded or hard-to-access sensors—an essential for fire departments, training centers, power plants, and utility facilities.

Engineered initially for in situ testing of helicopter engine sensors at extreme temperatures, the T-VAL has become a favorite in the Fire Industry, streamlining the calibration of sensors within smokestacks, overhead piping, burn buildings, and live fire training centers. The system’s advanced features include independently grounded and isolated heating elements for even thermal distribution, internal shielding to protect against excessive line noise and ground loops, and an automatic power shut off for immediate safety in the event of an internal sensor fault.

With a temperature range from ambient to 700°C (1292°F), the T-VAL is ideal for both routine checks and demanding calibration scenarios. Its robustness ensures reliable operation in the field, while its American craftsmanship guarantees quality and longevity. By enabling electrical loop validation during sensor testing, the T-VAL greatly simplifies troubleshooting, saving time, reducing downtime, and enhancing safety.

When lives are on the line, trust EDL’s commitment to excellence. Firefighters and industry professionals rely on the T-VAL to ensure their sensors perform without fail in critical situations. Proudly made in America, the TVAL Remote Head Drywell Calibrator stands as a testament to our dedication to protecting those who protect us.
