    Fast Shipping
    After you buy, you shouldn’t have to wait weeks for your gear to arrive. We ship fast so you can keep your cleanroom project on schedule.

    We service everything we sell. That means you get faster troubleshooting support and better response times than you would with other manufacturers or manufacturer’s reps.

    Special pricing is available for your business. Contact us and set up an account to make sure you get the best price available on every purchase.

    We guarantee you’ll get the right instrument for your cleanroom. If it isn’t exactly right, we’ll swap it out and find the right choice. If for some reason we don’t carry what you need, we’ll point you to a source that does (we’ll never sell you an alternative that doesn’t do exactly what you need it to do).


    The PAMAS OLS50P is equipped with a wear resistant ceramic piston pump. The pump provides a constant flow rate of 10 or 25 ml/min at a pressure range from 0 to 6 bar. 

    For data transfer, the user has the choice between digital and analogue interfaces. A RS485 data interface is part of the instrument’s standard equipment for digital data transfer. The analogue 4-20 mA channel transmits data to a PLC (Programmable Logic Controller). This interface function makes the PAMAS OLS50P an effective instrument for condition monitoring.
