Integrated Potentiostat and Multiplexer
EmStatMUX8
Based upon the EmStat range, there are two types of multiplexers to suit most types of sensor array work. The MUX8 is the most flexible offering the ability to connect arrays made of up to eight working electrodes in two or three electrode cell types and chips sharing a reference electrode and/or counter electrode. The MUX16 is suitable for sensor arrays or chips with sixteen working electrodes all sharing a RE and/or a CE. Both instruments are suitable for laminated layer corrosion analysis.The potentiostat is controlled and powered by USB and is used with PSTrace allowing for simultaneous sampling of each channel at a rate of 25 ms/channel. Standard packaging includes a shielded cable with connections for a working, a counter and a reference electrode by means of 2 mm banana connectors and mini-crocodile clips, a stripped end, Dsub-37 terminated flat cable and a USB cable. To make connections to chips simpler the Connection Terminal is an optional extra providing clearly marked screw terminals to the electrodes and can be directly joined to the ESMUX via their D-Sub connectors.

Hygrometers
A hygrometer is a device used to measure humidity. Many hygrometer products also measure temperature. A hygrometer that measures both humidity and temperature often is referred to as a thermo-hygrometer. PCE Instruments (PCE) offers a wide variety of hygrometer products used to measure the relative humidity of the air.Since humidity is an important factor in many sectors including but not limited to manufacturing, agriculture, construction, restoration, remediation and heating, ventilation and air conditioning (HVAC), PCE also carries a number of hygrometer devices designed for specific applications such as measuring the humidity in bales of pressed hay or in rolls of paper. A hygrometer also can be used to evaluate heat stress risk in hot work environments like boiler rooms, factories, construction sites and commercial bakeries. To accurately assess heat stress risk, a hygrometer capable of detecting and classifying temperature in relation to the amount of moisture content in the air is recommended. The global standard description for heat stress is the Wet Bulb Globe Temperature Index (WBGT). A combination hygrometer / thermometer, or thermo-hygrometer, can be used to verify the integrity of the cold chain during the transport and warehousing of refrigerated food and pharmaceutical products. This versatile and popular style of hygrometer also is ideal for evaluating the performance of HVAC systems in industrial, commercial and residential properties. If the humidity indoors is too high, mold can occur. Certain types of mold cause respiratory problems and other negative health effects for people living or working in the surrounding environment. In addition, mold that has permeated into the walls or roof of a structure must be removed for safety reasons. Mold remediation and removal, also called mold damage restoration, can be a costly endeavor, which is why preventative monitoring of the humidity indoors is preferable whenever possible.

Automated System for Identification and Control of Pharmaceutical Codes
The automated system for identifying pharmaceutical codes includes two scanners of the pharmaceutical code, two sensors for the presence of an object and a data processing unit (BOD). When the box or instructions are passed under the object presence sensors, the farm code is read by the corresponding scanner and the results are transmitted to the computer via the Ethernet interface. The BOD verifies the correctness of the read out farm code by comparing this code with the reference farm code set at the beginning of the system operation. If the farm code has not been read or does not match the standard, the packaging machine stops and the type of error is displayed on the indicators.
