Abstract

MéTODOS, SISTEMAS E DISPOSITIVOS PARA TESTAR SENSORES DE GáS E CORRIGIR SAìDA DE SENSORES DE GáS. A presente invenção refere-se a um método de ajuste da saída de um sensor eletroquímico que inclui as etapas de: simular a presença de um gás analisado eletronicamente; medir uma resposta do sensor á simulação eletrónica; e ajustar a saída do sensor em função da resposta medida para a simulação eletrónica, O método de ajuste da saída de um sensor eletroquímico, tendo um eletrodo operacional e um contra-eletrodo, inclui de preferência as etapas de: provocar eletronicamente um escoamento de uma corrente entre o eletrodo operacional e o contra-eletrodo; medir uma resposta do sensor á demanda de corrente; e usar a resposta medida para ajustar a saída do sensor, durante amostragem de um gás analisado.
