12.2 TEMPERATURE REGULATOR
On version SP2000
–H320/S the temperature regulation is effected by the capillary thermostat
mounted inside the connecting box. The range of regulation is from 50 to 320°C.
On the versions SP2000-H320/S1 and SP2000-H320/S2 the regulation is made by means of an ex-
ternal electronic regulator. M&C supplies appropriate temperature regulators, eg. Type 703G (see
data sheet 2-5.1) or Type 703G double that can be mounted separately or directly on the gas sample
probe (max. ambient temperature +45°C).

In case gas has to be sampled behind wet washers, the Demister sampling tube of PVDF with con-
nector G ¾” has to be applied in order to evacuate the droplets:
