PHAMP-1 Battery-Powered pH/ORP Pre-Amplifier by Sensorex

The PHAMP-1 is a battery-powered unity-gain preamplifier that allows the user to run cables up to 1000 feet between the electrode and pH/ORP controller/meter. The PHAMP-1 should be located close to the electrode for optimum use. High impedance pH signals are reduced from megohms to under 20,000 ohms. By locating the device near the electrode, the service life of the electrodes can be enhanced through the elimination of noise from cable runs. Sealed to keep out moisture, the PHAMP-1 is self powered by two three-volt lithium cells and has an estimated lifetime of three years. Simply plug in any pH or ORP electrode equipped with a BNC connector, plug in the extension cable and then you are finished!

• Provides for long cable runs
• Extends electrode service life
• Easy installation
• Works with almost any make or model pH/ORP controller
• Lithium cells for long service life

FC51K 200uL Low Volume PVDF Flow Cell includes 2 each 1/16" Tube Fittings by Sensorex

Sensorex manufactures fast response 50 and 200 microliter internal volume flow cells for pH measurement. All cells are made of clear Acrylic or Kynar (PVDF). Designs include 1/16" inlet and outlet fittings. All cells use the standard, economical Sensorex 450CD Flat Surface Combination pH/Reference Electrode or a special version of 450CD with 100psig pressure tolerance (model 970277).

The pH Detectors are designed for use with a variety of instrumental techniques such as FIA, HPLC and IEF and are also used to continuously monitor the pH of low volume flows in bench scale chemical systems.

Both the 50 and 200 microliter internal volume flow cells areavailable in acrylic or PVDF and are supplied with inlet and outlet fittings sized for standard 1/16" OD tubing. The cells' ports have 1/4-28 threads which accept a variety of other tube fittings.

Very low internal volumes are achieved by using a flat surface pH electrode located at the top of the flow cavity. The resulting rectangular cross-section flow path has no protruding parts which could interfere with a clean sweeping flow. The result of this design is the fast system response shown on the performance curves on page 2.

The Flat Surface Electrode, Sensorex Model 450CD, is a combination pH/Reference electrode with double reference junction design. It includes both a pH and reference half cell. The reference electrode is a sealed, gel-filled design and includes a peripheral, semi-porous polyethylene junction.

• Fast response!
• Choice of 200uL or ultra-low volume 50uL flow cells
• Acrylic or PVDF (biocompatible) materials of construction
• Supplied with flangeless 1/4-28 fittings for 1/16" OD for tubing
• Use with Flat-Surface Easy-To-Clean Electrode
• Model available for 100psi use
