Limit of permissible variation of indications, in shares of the limit of permissible basic errors
0,5
Limits of permissible additional error from the influence of changes in ambient and analyzed
environments in operating conditions for every 10 ° С from the temperature of determination of the
main error, in fractions of the limit of permissible basic error:
-
for measuring channels of combustible gases and carbon dioxide
±0,5
