L’unità PTB330S combina un barometro PTB330 con un indicatore portatile MI70 (che alimenta gli strumenti e fornisce il display per visualizzare i dati) ed (opzionale) una sonda HMP155 per temperatura ed umidità. Lo strumento è adatto ad effettuare misure di riferimento in ambito meteorologico e industriale; viene dotato di valigetta da trasporto weatherproof per una facile movimentazione.
