The HNT50 Infrared Temperature Controller is an integrated, highly precise non-contact thermal monitoring instrument. By capturing the passive infrared radiation energy emitted by target objects within the 8–14μm spectral range, the device calculates the exact surface temperature in real-time without any physical contact.
Features
Durable 304 stainless steel housing withstands shocks, vibration, and corrosive industrial environments.
Standard M18×1 threaded barrel ensures fast and stable installation in industrial systems.
Air purge jacket prevents dust, smoke, and steam from affecting the optical lens.
A laser pointer provides precise and easy target alignment.
150ms fast response captures rapid temperature changes in real time.
Wide 0–1200℃ measurement range supports multiple industrial applications.
High accuracy of ±1% or ±1.5℃ ensures reliable temperature readings.
Flexible output supports 4–20mA and RS485 ModBus integration.
IP54 protection ensures stable operation in harsh environments.
