New All-in-One Industrial Humidity and Temperature Transmitter
The new HF8 humidity and temperature transmitters from Rotronic (Switzerland) are ideal for fixed- installation applications requiring high precision measurements. Based on the new advanced AirChip3000 technology, the HygroFlex8 communicates with all HygroClip2 probe types which utilise Rotronic’s time tested sensors and are used in thousands of applications worldwide.
Together with the digital HygroClip2 probes, the HygroFlex8 is one of the most versatile and precise humidity and temperature measuring instruments available on the market.
With a measurement accuracy of 0.8% RH and 0.1ºC, the instruments can measure humidity ranges from 0 to 100%RH and overall temperature ranges of -100 to 200ºC depending on the type of probe being used. The latest AirChip3000 technology guarantees an automatic sensor test, drift compensation and every probe is temperature compensated with over 30,000 data points to maintain the highest possible accuracy over the entire
measuring range. The HF8 has two probe inputs and the optional HW4 software allows users to configure the connected HygroClip2 or
3rd party analog probes exactly to their needs. Each HF8 has 4 analog outputs and 4 alarm relays programmable to any probe input and any probe parameter, including all psychrometric calculations such as dew point or wet-bulb. Audible and visual alarms can be activated as well. The data logging function on the HygroFlex 8 allows recording of up to 20,000 data points with date and time stamp. Users can configure the logging intervals and download, store and graph the data with the HW4 software.
The optional digital outputs additionally enable connection to a network via Ethernet and Power over Ethernet (POE). If the user so wishes, the HF8 can be integrated into an RS485 network and/or make multi-drop connections in which an unlimited number of devices can be connected. All this complies with FDA CFR 21 part 11 and GAMP regulatory requirements when used with the HW4 software.

InnovX Systems (USA) introduces their new family of handheld XRF analysers – the DELTA Line. The re- sult of InnovX's extensive field portable instrumentation experience and innovation leadership, the DELTA Line satisfies an urgent demand in the analytical industry. That is, a handheld XRF fully ruggedised to industrial standards – including no PDA or movable display – to withstand harsh environments while at the same time providing peerless analytical performance.
InnovX founder and CEO Don Sackett remarked, "I am really proud of the accomplishments of our de- velopment teams. They've redesigned our analysers from the ground up to create a true inspection tool that is both analytically superior AND rugged enough for virtually any environment - NO COMPROMISES. The DELTA analysers feature the latest technology to optimise analysis throughput and uptime."
Exclusive to InnovX's DELTA Line of analysers is their auto-calibrating, auto-charging docking station. With the unique, first of its kind DELTA docking station, operators never have to power
their analyser off – the station charges the analyser battery and a spare, and periodically performs a calibration check. Remove the analyser anytime for immediate testing - industrial efficiency at its best

New Entry-level Spectrophotometers Narrow the Bandwidth
Jenway’s (UK) new 73 series spectrophotometer range provides entry-level instruments with a narrower spectral bandwidth of 5nm and an improved absorbance range of -0.3 to 2.5A, all within an innovative space-saving design.
The patent pending design of the 73 series cleverly minimises the overall footprint of the instrument by incorporating the large graphical display into the instrumentís lid. The easy-to-read display is ideal for demonstrations and enables live spectrum and kinetics scans to be clearly viewed. The instruments have the additional option of an integral printer, for further space saving - an important benefit in situations, such as teaching laboratories, where bench space is at a premium.
All four models are supplied with free bi-directional PC software. The advanced models, 7310 and 7315, also have the additional feature of an easy access USB port on the front of the instrument which enables results and methods to be saved directly to a USB memory stick.

Soil Moisture Plus Temperature Sensor
The SM300 from Delta T-Devices measures soil moisture and temperature with research grade accuracy: Soil moisture and temperature; Dependable accuracy ± 2.5%; Good temperature and salinity stability and Easy data logger connection (0-1V).
The SM300 offers outstanding
performance in mineral, organic and saline soil conditions, and it is stable across wide ranges of temperature and salinity. The SM300’s
construction uses industrial grade connectors and high specification materials throughout to produce a soil moisture sensor of outstanding quality. The built-in temperature sensor simplifies soil temperature measurement and achieves 0.5ºC accuracy.
The SM300 minimises soil disturbance, preserving the original soil structure around the measurement rods. It is easy to insert and install whether at the soil surface or at depth. The SM300’s circular shape facilitates installation in augered holes - extension tubes are available.
The SM300 is a dual-purpose probe - it can be used both with the Delta-T HH2 hand-held Moisture Meter for instant moisture readings, or left in situ for data logging of moisture and temperature.
The SM300 is compatible with all Delta-T data loggers; they provide cost effective solutions for recording up to 60 sensors. In fact the SM300 can be connected to most types of data logger (simple 0 to 1V DC output for water content).

The presence of excessive water in plastics adversely affects the performance of polymeric goods. This is why water determination is of crucial importance. Metrohm (Switzerland) describes the straightforward and accurate determination of the water content using the Karl Fischer Oven Method in ten different plastic types.
The plastic sample being tested is heated in a
hermetically sealed vial. The moisture liberated from the sample is transferred via a dry carrier gas stream into the titration cell where it is coulometrically titrated. For every plastic type, the optimum oven temperature can be determined in a water release curve. This procedure ensures fast and quantitative water extraction in a reasonable time while, very importantly, excluding interfering decomposition reactions.
Thermally stable polycarbonates, fibre-reinforced polyesters and acrylonitrile-butadiene-styrene (ABS) resins need to be heated to 230o
less stable resins such as polyamides and PVC need only to be heated to 150 and 100o
C, respectively.
determined: Terluran® Natural;Ultramid®
The water content in the following plastics was GP-22 Natural; Grilamid®
TR 55 A3K Natural; Ultramid® (recycled); PET regrind (new); PVC. A3K Black;
Ultramid A 3H-G5 Black; Grivory HTV-3H1 Natural; Makrolon®
