The Portalevel® Mini uses Coltraco’s long-trusted 7th Generation technology and has been the essential tool for all Fire Servicing Technicians for over 15 years.

Throughout this time the Portalevel Mini® has undergone numerous upgrade programs to further refine the platform and provides the ideal solution for the vast majority of fire suppression cylinder inspection requirements. Accurate to +/-1.5mm on all major agents including CO2, FM200®, NOVEC 1230 and other similar agents, we recommend the Mini® for any cylinder up to about 400KG of Agent.

The device is completely handsfree, with the main unit hanging around the operator’s neck allowing the service technician to have two hands available to work. With the SPA feature, the signal output can be increased when working on challenging or corroded cylinders and a simple LED indication showing when liquid is detected.

It is the most popular Ultrasonic Liquid Level Indicator Technology ever produced with over 20,000 devices in use worldwide. As with all units we provide, it comes with the full Coltraco Customer Commitment, including free Training and Technical Support for the life of the unit, 3 Year Warranty with full replacement in the event of any defect, guaranteed trade-in buy-back when upgrading to newer devices and with the most proven technology on the market.
