This manual covers the NEMOTO NAP-100A series hot-wire type gas sensor for light industrial applications, including usage instructions and specifications.
The NEMOTO NAP-100A series is a hot-wire type gas sensor designed for light industrial applications, specifically for monitoring combustible gases. The series includes three models: NAP-100AD (sintered metal cap), NAP-100AM (mesh cap), and NAP-100AC (brass cap). These sensors offer excellent output linearity, superior reproducibility, and durability against corrosion gases. This manual is written in Japanese.
| Objective gases | Combustible gases |
|---|---|
| Measuring range | 1 ~ 100 %LEL |
| Supply voltage | 2.6 +/ - 0.13 V |
| Current consumption | 170 ~ 180 mA |
| Operational Temp. & Humidity (NAP-100AD) | -30 ~ +250oC, Less than 95 %RH |

They are used for gas leakage detectors in plants and industrial areas, distinguishing gasoline from diesel oil at gas stands, and as gas detectors in gas cylinder refilling facilities.
Preparatory aging for at least 10 minutes is required before zero point adjustment.
The mount base for the NAP-100AD model is made of Alumina.
