Pump Features
All Models
Battery charging options
SKC offer two battery charger options for the Universal MTX series pumps, a single
charger (Part No. 223-203A) and a five station charger (Part No. 223-103A). Both charger
models provide optimum charging of the NiMH battery packs used in the Universal MTX
series pumps, based on a timed (16 hour) constant current charging phase followed by
a switch to a trickle charging rate to prevent overcharging.
Mains power option
The Universal MTX series pumps can also be powered from the electrical mains supply
using a ‘battery eliminator’ (Part Nos. 223-305B - Euro 2 pin plug, 223-305C UK 3 pin
plug). This accessory comprises a mains adaptor and dummy battery pack which is fitted
to the pump in place of the standard battery pack. Please note that the pump’s ATEX
certification is invalidated when using the battery eliminator, and therefore
must not be
used in hazardous areas when the battery eliminator is fitted.
Anti-tamper cover
The pump controls are situated beneath a clear anti-tamper cover, requiring a tool for
removal. This helps prevent tampering during a sample run.
Low battery shutdown
Automatic pump shutdown in the event of a low battery condition. Prevents degradation
of battery pack due to over-discharge.
Flow indicator
Built in rotameter to indicate airflow during sampling. Gives visual indication of changes in
flow rate during a sample due to filter loading or constricted tubing for example. Note the
flow indicator
must not
be used to calibrate the sample flow rate.
Particulate trap
Built in replaceable filter to trap particles that would otherwise contaminate the pump
mechanism.
