PH-1 Turns iPhone, iPod, or iPad into Portable pH Meter
Sensorex (USA) has developed an industry-first mobile accessory for pH measurements. Compatible with Apple iPod, iPhone and iPad devices, the PH-1 pH meter accessory measures and records pH values in the lab or field for use in environmental, education and industrial applications.
The patent-pending PH-1 accessory plugs into the standard Apple dock connector and uses a Sensorex pH electrode to measure pH with accuracy to .01 pH. The free Sensorex app displays pH, millivolts, ambient temperature and solution temperature in real time. The CE marked device supports 1, 2, 3, or more calibration points and sends readings by email for later analysis. When used with a GPS-enabled device, the pH meter app will record measurements with both timestamp and geographic coordinates,
eliminating transcription errors and improving efficiency.
Powered from the Apple device, the PH-1 requires no supplemental energy source. Its pH measurement range is 0-14 pH and it operates in ambient temperatures of 0-40° C, in solutions of 0-100° C. Data history can be grouped by date or location and exported individually or in .csv format via email.

Hydraulic Diaphragm Pumps Showcased
At the recent ACHEMA 2012 ProMinent (Germany) showcased its new Hydro/ 4 hydraulic diaphragm pumps. It supplements the Hydro/ 2 and Hydro/ 3 types thereby extending the range of application of the product range to the higher capacity ranges. The Hydro/ 4 is equipped with a PTFE multi-layer metering diaphragm.
With material versions from stainless steel, PVDF and Hastelloy C, the Hydro/ 4 can be used universally in multiple applications. It covers the capacity range from 130 l/h – 1,680 l/h at 25 bar to 7 bar absolute.
All pump types are equipped as standard with a fixed-setting pressure relief valve that is integrated in the hydraulics and a multi-layer diaphragm with a diaphragm rupture warning system. The reproducibility of the metering is better than ±1 % in the stroke length range of 20% -100 % given defined conditions and correct installation.
The multi-layer diaphragm ensure safe and leakage free metering.
Efficient process pumps type hydro enhances the process- and product quality due to reliable metering. Simultaneous the requirements of the chemical industry and protection of environment will be fulfilled. High availability and safety of process during metering of combustive, toxic, solids containing and viscous fluids will be ensured.

New White Paper features Solvents for Oil and Grease in Water Measurements
A White Paper entitled, “Solvent Choices for Infrared Testing of Oil and Grease in Water” was recently published by Wilks Enterprise (USA). Infrared (IR) analysis is widely used worldwide for determining the amount of oil and grease in water as it is a cost- effective measurement technique that can be easily done on-site or in a laboratory. Since water is a strong absorber in the mid-IR region where oil and grease is measured, a solvent is used to extract the oil prior to analysis. As there are numerous solvents that can be used for oil in water measurements, it is important to know the various factors that should be considered when choosing a suitable solvent.
This White Paper discusses a number of factors that will affect solvent choice including measurement range of samples, availability of solvent, cost, toxicity, disposal requirements, and flammability.
