NP-1000 Portable Combustible Gas Detector (0-100 vol%)
The NP-1000 portable combustible gas detector has attractive features, including: direct reading of 5 target gases, data logging, pump boost, ingress proof rating IP67, Intrinsically safe with ATEX approval for hazardous areas. Ideal for checking gas leaks or monitoring the presence of gas in hazardous areas typically found in oil refineries and petrochemical plants.
The Riken Keiki NP-1000 portable combustible gas detector supersedes and builds on the previous model GP-88A, using latest technology and advanced features. A safety rating of ExiaⅡCT4 allows users to detect a gas at hazardous area Zone 0 where an explosion hazard always exists. Calibration is to one gas only ( methane or ISO-butane ), then select from any of the 3 base gases (air, N2, and CO2) can be selected by a simple button operation. Optional filters can be used with the standard gas sampling probe to remove hydrogen sulphide (H2S), or silicone that would normally damage this type of catalytic sensor.
Target Gas can be selected from a list of 5 gases, only 1 gas (CH4) is required for calibration
Pump Boost ( higher pump rate gives faster sampling and long distance suction)
New probe / Tefron tube are applied as standard
Continuous operation for 20 hours
Intrinsic safety ex-proof
IP 67 rating
Data logger available
1st & 2nd gas alarm points
Automatically switch over from “Low-range” to “High-range” and “High-range” to “Low-range”
