o Refrigerants in ppm range

Differently from other sensors in the market, IRNET-P sensors feature a microprocessor for internal

signal processing, offering an engineerized output, already linearized and temperature compensated.

IRNET-P sensors are suited for instrument manufactures also without any specific knowledge in IR

technology.

NDIR Sensors

All NDIR sensor manufactured by N.E.T. share these features:

o Patented optical path

o Internal high performance microprocessor

o Extended calbration and testing for each sensor

o 20 or 32 mm industrial standard size and pinout

o Extended temperature range

o Fast T90 response time

o ModBus or P2P communication protocol

o Solid, rugged construction with stainless steel enclosure

o Water Filter

o Voltage output and optional bridge output

o Low power consumption version for portable applications
