Product Overview
Thermal 14571 Dual Power Thermistor Vacuum Gauge – Used
Used analog vacuum gauge tested to power on using both 115 VAC input and two D-cell batteries. No calibration or full performance testing was performed. Includes Thermal 4510 thermistor vacuum sensor. Unit only, no additional accessories or documentation included. Typically ships same business day from Idaho warehouse. Delivery to lower 48 states usually 3-5 business days.
The Thermal model 14571 is an analog thermistor-based vacuum gauge designed to provide direct needle indication of vacuum levels in laboratory and industrial systems.
Product Condition
Used. Gauge is in nice cosmetic condition based on visual inspection. Powers on correctly using both AC line power and battery operation. Calibration and accuracy were not verified.
Product Overview
Thermal has long produced practical vacuum measurement instruments used in service labs, research environments, and equipment maintenance settings. The 14571 relies on thermistor sensing technology paired with an analog meter movement, offering immediate visual feedback without digital processing. Dual power capability allows the unit to operate from standard line voltage or batteries, supporting both fixed bench use and portable checks.

Frequently Asked Questions
What testing has been performed?
The gauge was tested to power on using both 115 VAC input and battery power. Calibration and full performance verification were not performed.
What sensor is included?
The listing includes a Thermal 4510 thermistor vacuum sensor.
Can the gauge operate without AC power?
Yes. It can run on two D-cell batteries for portable operation.
Is this suitable for modern vacuum systems?
It is best suited for systems designed for or compatible with thermistor-based vacuum measurement.
Does it require external electronics or software?
No. The 14571 is a self-contained analog instrument.
Built for benches where a needle and scale told the story, this Thermal gauge continues to offer steady, readable vacuum indication without reliance on menus or firmware.
