ENVEA - Model SM-4 Mobile -Modular Mercury Stack Gas Monitor QAL 1 Certified
FromENVEA
Technically identical to the SM-4, this device is ideal for mercury determination at varying sites. The SM-4 Mobile by Mercury Instruments has been developed on the basis of the well proven SM-4 mercury stack gas monitor. Its measurement principle and technique, its thermocatalytic reactor, the detector and the sample probe are identical with those of the stationary SM-4.
