KNF IP65 UFEM 1.10 TT.18RCP2 Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to su (more)it most laboratory liquid metering and dosing needs. The UFEM 1.10 FT.18RCP2 version has a liquid transfer flow rate of 1 – 100 mL/min and discreet dosing volumes of 1 – 999 mL. It is constructed with the following chemically-resistant fluoropolymer flow path materials: PTFE head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. Besides onboard manual control, this pump offers analog control, start/stop and reset/prime TTL logic control, output signal fault alarm, and RS 232 PC control. A RC control interface cable and RS 232 cable with D-Sub 9 connector are included. A foot switch for start and stop impulses is available. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduces flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 10 pumps are self-priming up to 9.8 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue.

CY10 scale’s multi functions The CY10 series multifuncional scale is designed for fast, accura (more)te and repeatable weight determination. It comes with an advanced PUE CY10 terminal, and that means working comfort with a 10-inch high-resolution display with a smooth and intuitive interface. Software for special tasks Thanks to the terminal advanced software, the CY10 multifuncional scale: Cooperates with up to 2 weighing platforms Continuously updates all statistical data after the next measurement is entered into the balance’s memory – either globally (regardless of the weighed commodity) or separately for each weighed commodity selected from the database Has a Tare mode expanded to include End-product issue mode capability Works with RFID tags* (accessing personal data as well as marking specific goods or recipe ingredients in the database). Multifunctional scale, including labelling scale If you need a labeling scale, the CY10 is the perfect solution. With a terminal that: Cooperates with the computer program Label Editor R02 Is compatible with ZEBRA label printers Supports single labels, bulk labels and bulk from bulk labels Allows import/ export of label designs using a pendrive Enables you to assign labels to goods or customers and print a global label The CY10 series multifuncional scale can operate as a labeling scale. Light or dark? Which color theme will you set on your CY10 balance? Both are user-friendly and clear, but we are curious which one you like more. Modbus TCP/IP is one of the most popular communication protocols in industrial automation. Implementing it in the 5Y balances and CY10 scales makes the devices of this series friendly to automation integrators. A balance or scale in a Modbus system is a slave device and performs tasks specified by the master device which is most often a PLC. Protocol Modbus TCP/IP in the 5Y balances and C10 scales enables, among other things, the realization of mass readout, zeroing and tare functions of the device, as well as tare settings and MIN and MAX thresholds. * RFID ISO/IEC 14443 Type A, 13,56 MHz
