NEW LOW COST ELECTROCHEMICAL SENSORS FOR DISPOSABLE PORTABLES

The NT-XX-6D Range

NT-CO-6D (Carbon Monoxide)

NT-H2S-6D (Hydrogen Sulphide)

The NT-XX-6D range of Electrochemical Gas Sensors are  a new generation of gas sensors designed specifically for use in the latest disposable industrial "clip"  type gas alarms. Configured for a lifetime of 6 months, The NT-XX-6D range combines cost effectiveness and high performance in a design conscious package at very low cost. Available for both Hydrogen Sulphide and Carbon monoxide (with other gases pending).

Nemoto's porous electrode technology enables accurate gas detection with high sensitivity. The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage. The sensors are available either with solder pins (which may be soldered directly) or complete with pcb sockets, to facilitate ease of manucture for our customers. We believe these new sensors from Nemoto represent the automatic choice of sensor for any manufacturer designing a 6-month disposable instrument.
