Portable Gas Detectors

1000 Series

Pumped Combustible Gas Monitors %LEL / % VOL / PPM Ranges

The 1000 Series allows users to directly read up to 25 combustible gases. Including Hydrogen as-well-as Argon and Helium. There are 3 versions for %LEL, %vol and ppm ranges. The NP-1000 for %vol can measure Hydrogen in an inert atmosphere such as Nitrogen or CO2, making it ideal for purging applications.

Product Features

Three single gas portable models for ppm, %LEL, and %VOL for Hydrogen and other combustible gases. The NC-1000 has a range of 0-10000 ppm, the GP-1000 has a range of 0-100% LEL, and the NP-1000 has a range of 0-100% Volume.

The 1000 Series have several attractive features allowing users to directly read up to 25 target gases (5 for NP-1000). There is a large intuitive display as well as a strong backlight. Datalogging in addition to a pump boost mode for long sampling lines, are also included.

Single Combustible gas calibration

1000 series comes calibrated to either Methane or Iso-Butane. Users can then select any one of 25 target gases by a simple button operation. Optional filters can be used with the standard gas sampling probe to remove Hydrogen sulphide (H2S) or Silicone contaminants. These gases normally damage this type of catalytic sensor.

The instruments have ingress proof rating of IP67 and are Intrinsically safe in addition to having ATEX approval. A safety rating of Ex ia ⅡC T4 allows users to detect a gas at hazardous area Zone 0, areas where an explosion risk always exists.

Customers find the 1000 series is ideal for checking gas leaks or monitoring gas in oil refineries, petrochemical plants. In addition, the Hydrogen calibrated version is ideal for use in power stations as well as fuel cell leak checking.

NP-1000 Hydrogen Detector

The NP-1000-H2 is a version calibrated specifically for Hydrogen in the range of 0-10% Volume or 0-100% Volume. The NP-1000 is ideal for use in Fuel Cell environments, Power station Generator purging, in addition to many other Hydrogen Economy applications.

The 1000 series are small, light, and compact in addition to being very easy for users to operate. They operate with 4 x Alkaline batteries allowing continuous operation of up to 20 hours. The 1000 series has a strong on-board pump with pump boost which allows use with long sampling lines up to 30 meters.

Accessories

Users benefit from standard accessories which include a 0.75m hose as well as a probe. Users can specify optional accessories which include data logging software, carry case in addition to H2S filters and sampling hoses. In addition, see links to the complimentary instruments below.
