NH-300G fully-adjustable frame heater with continuous temperature dial and cold/hot air switching — the precision variant of the NH-300 for fine-step temperature control.
Clinical overview
The OpticsMED NH-300G upgrades the NH-300's 4-step temperature to a fully continuous adjustable dial — lets the dispenser dial in any temperature within the operating range instead of choosing between 4 discrete steps. The cold/hot air switching capability and 5-minute auto-off safety stay the same.

Boutique opticians and premium dispensing benches handling diverse frame materials where the precision of continuous temperature adjustment matters more than the simplicity of 4 stepped options.
