COMPLETE LIST OF AVAILABLE REFRIGERANT SENSORS

NET offers the most complete range of Non-Dispersive (NDIR) sensors on the market today for refrigerant gas detection: 44 common gases, plus two more currently under development. Those gases are available across 3 different platforms (IRNET PRO, IREF PRO, IREF LITE) and the available ranges vary according to the specific gas. For example, non-flammable refrigerants may be available only in...

DETECTING AMMONIA WITH NET IREF PRO NDIR SENSORS

Ammonia is a among the most common gases found in the industry. Vastly used in wastewater treatment, leather, rubber, paper, food and beverage industries, it is also making a strong comeback in cold storage applications and refrigeration systems due to its environmental friendliness. Ammonia toxicity is well known. The pungent smell of ammonia in the air is detectable at concentrations...

SENSOR INSTALLATION GUIDELINES

NET manufactures and sells a complete range of gas sensing devices on an OEM basis for industrial and commercial applications used by instrument manufacturers worldwide. NET does not manufacture complete instruments or detectors and let alone complete gas detection systems. Nonetheless, oftentimes users ask us for sensor installation guidelines in terms of number and location of sensors. This is a...

THE IRNET PRO CROSS REFERENCE FACTOR MANUAL

In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Different Hydrocarbons have different number of atoms and molecular structure, but in most cases, they can be detected in a common area of the Infrared Spectrum, between 3.0 and 3.5 microns. In other words, a certain degree of cross-sensitivity exists between different hydrocarbon gases as...

ELECTROCHEMICAL CELLS: CELL LIFE / STORAGE LIFE / WARRANTY

NET offers a strong range of electrochemical cells for the detection of the most common toxic gases, including CO, H2S, CL2, SO2, NH3… in different safety applications. This very cost-effective technology has been used in the industry since the 1960s. Users often ask us clarification about 3 important parameters and the differences among them: cell life, storage life and...

THE IREF PRO CROSS REFERENCE FACTOR MANUAL

Over the years, NET has determined cross factors allowing specific IREF PRO sensors - notably, R-125, R-134a, R-32, R-507, R-1234yf and R-1234ze sensors - to be used when detecting multiple other refrigerant gases, including some gases for which a dedicated sensor is not available yet from NET. This feature is extremely useful for user who wants to rationalize their P/Ns...
