Product Introduction

 

 

  SP2nd is Simple Gas Alarm Detector that is required to protect users’ safety at 

dangerous  work  environments.  The  apparatus  can  indicate  simultaneously  the 

concentration of gases (Oxygen, Carbon Monoxide, Hydrogen Sulfide, Hydrogen, 

Sulfur Dioxide, Hydrogen Chloride, Ammonia and etc.) on a digital LCD monitor, 

and the methods of operation and calibration are easy and convenient.   

  This  instrument  alerts  accurately  the  alarm  circumstances  to  operators  and 

workers  for  their  safety  with  its  functions  of  loud  alarm  sound  and  vibration, 

when higher gas concentration than normality is detected. Besides, it is available 

for  users  to  check  upon  occasion  and  adjust  the  value  of  alarm  to  the  work 

environment  on  demand,  since  it  has  the  function  of  indicating  minimal  and 

maximal  concentration  of  the  gases.  It  is  also  possible  to  prevent  in  advance 

workers from the danger of exposing for a definite period of time to such toxic 

gases  as  Hydrogen  Sulfide(H

2

S),  Carbon  Monoxide(CO)  and  Sulfur  Dioxide(SO

2

by  its  function  of  STEL(Short  Term  Exposure  Limit)  and  TWA(Time  Weighted 

Average).
