Description

Gastec GOA-7H-S Oxygen detector

Gastec GOA-7H-S Oxygen detector can quickly and accurately measure oxygen concentrations at a variety of different work sites subject to host of complicated and varying factors.

GASTEC Detector indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavour to achieve highest quality detector tubes for analysing airborne gases/vapours, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society. Tubes are now available for more than 500 different applications.

*The GOA-7H-S comes with a 5 m sensor cord.

Small, compact and lightweight, only 110g
One-touch calibration to oxygen levels of 20.9%
Explosion proof
Low power consumption

Specifications

Parameter	Specification
Manufacturer	Gastec Corporation
Model Designation	GOA-7H-S
Target Gas	Oxygen (O2)
Detection Principle	Galvanic Cell (Electrochemical)
Measurement Range	$0.0%text{ to }25.0%text{ }text{O}_2$ volume
Sensor Connection	External sensor head on extendable spiral cable
Alarm Preset Levels	Low Alarm: $le 19.5%text{ }text{O}_2$ (Deficiency) High Alarm: $ge 23.5%text{ }text{O}_2$ Enrichment
Response Speed ( $T_{90}$ )	$< 20text{ seconds}$

Operating Conditions	-10°C to +40°C (14°F to 104°F); 10–90% RH non-condensing

Features

External Spiral Cable Sensor: Features a compact sensor head mounted on a flexible, expandable spiral cable for reaching around pipes, into machinery spaces, or into narrow openings before entry.
Galvanic Cell Sensing Unit: Uses a self-powered electrochemical cell that provides real-time oxygen monitoring with no warm-up delays or external sensor bias power required.
Triple Alarm Matrix: Equipped with an $85text{ dB}$ audible buzzer, bright LED indicator flashing lights, and internal vibration alerts to ensure immediate detection in noisy work areas.

Applications

Local Pre-Entry Spot Checking: Testing small vessel openings, inspection hatches, and utility pits prior to operator entry.
Personal Breathing Zone Safety: Clip-on protection for personnel working near gas lines, inert gas purge systems, or cryogenic storage units.
Inert Gas Leak Tracing: Checking seals and valves around nitrogen ( $text{N}_2$ ), argon ( $text{Ar}$ ), and helium ( $text{He}$ ) piping.
