Information saved

The knowledge can be saved when irregular alarms and energy off.


Touch screen and Command Input


When Reset right after abnormal alarm and electricity on after off, the instrument routinely discharges residual reactants in the instrument and automatically resumes functioning status.

The unique design helps make this merchandise when compared to equivalent items with decrease failure rate, reduced routine maintenance, lower reagent use and greater value.
Injection factors: vacuum suction CZPT, and the pump tube amongst the reagent there is constantly an air buffer, to stay away from corrosion of the tubing, even though producing reagent mixing more concise and flexible.
Sealed Digestion components: high -temperature higher-strain digestion system, accelerating the response approach, to overcome the risky corrosive gasoline exposure method tools corrosion.
Reagent tube: imported transparent modified PTFE hose, diameter greater than 1.5mm, lowering the chance of h2o-like particles clogging.

one. CZPTal sampling inspection in huge watershed.
