The TUFF pump incorporates a proven efficient double acting diaphragm pump mechanism with precise digital control. This offers the user excellent real time flow control and stability across a wide range of sampling media.
The TUFF pumps convenient charging cradle allows single or multiple pumps and separate battery packs to be charged. Intelligent battery monitoring and fast / trickle charge control maintains optimum battery condition and service life. Full charge can be obtained in typically less than 5 hours on fast charge.
Embedded battery pack intelligence tracks state of charge, and long term battery condition.
- Single or 3 way charger formats
- Allows tidy, compact charging and storage of multiple units.
- Small storage footprint
- Integral Charge Status LED in spare battery packs
TUFF pumps are available with either 3 or 4.5 l/ min maximum flow rate capability. Standard, Plus and Pro models then provide different levels of functionality and programmability:
TUFF Standard Models:
Entry level pumps for abatement and general sampling applications. With simple single point flow setting, elapsed run time counter and run mode only. Simple battery life indication. Drop in fast charger.
TUFF Plus Models:
Offer additional functionality including: Display of flow set point, real time flow rate, accumulated sample time and volume. Programmable Run Duration mode. Upgradeable to Pro.
Intrinsically Safe (I.S.) Models:
I.S. models are used where hazardous atmospheres can be present from flammable gases or dusts. In this situation, IS models should be used. Additional models are available which satisfy the stringent requirements of mining applications that are rated to ‘M1’, the only pump in the world to have this level of certification.
TUFF Pro Models:
Offers advanced program functionality and download capabilities suited to the most demanding occupational and industrial hygiene applications. Offers all functionality of the Plus model with the addition of:- Intelligent Hours Remaining Battery ‘Fuel Gauge’, Time Weighted Average (TWA) sampling mode, 2 user defined timer programmes (9 on / off times) and onboard data logging for up to 100 runs with download capability to Casella Insight Data Management Software (see separate data sheet).
The units operate from removable 4.8V Nickel Metal Hydride (NiMH) rechargeable cells.
There are two capacities:
1.7Ah standard pack for general short term monitoring applications or the high capacity 2.7Ah versions where longer sampling durations may be required.
