    AWTherm – Water Activity Meter

    AWTherm Stabilized Temperature Water Activity Meter

    Stable temperature yields precise measurements.
    With AwTherm, ROTRONIC offers a professional, high-end laboratory unit for temperature-stabilized measurement of water activity in the foodstuffs, cosmetics, or pharmaceutical industries.
    The wide control range permits measurements to be integrated directly in the tempered manufacturing or storage process. Water-activity measurement reacts very sensitively to variances in temperature. Stabilizing the temperature prevents imprecise results due to external temperature influences.

    Exchangeable measuring head
    A further advantage of AwTherm is that the measuring head is removable, which means that the probe can be temperature-calibrated or adjusted to give high precision.

    The AwTherm shows its paces in island-operation mode, with its simple handling and clarity. No laboratory should be without the device in conjunction with the ROTRONIC HW4 software

    Why measure water activity?
    The free water in a product influences its microbiological, chemical and enzymatic stability. If there is too much free water present, the products spoil; too little water can be detrimental to the product characteristics.

    Water activity Contaminants
    aw = 0.91..0.95 Many bacteria
    aw = 0.88 Many yeasts
    aw = 0.80 Many mildews
    aw = 0.75 Halophile bacteria
    aw = 0.70 Osmiophile yeasts
    aw = 0.65 Xerophile mildew

    Measuring water activity provides useful information about characteristics such as cohesion, storage lifetime, clotting or pourability of powders, tablets, etc., or the adhesive properties of coatings.

    Cable and Pipe Locator | LKZ-2000

    Ingress protection IP65 labelBluetooth Enabled label

    Overview of Cable and Pipe Locator LKZ-2000

    Easily locate cables and pipes with pinpoint accuracy. The complexity of large underground utilities networks continually increase, therefor obtaining precise information on the location of specific buried cables and pipes has never been so important. To protect buried assets during ground excavation work and supporting the mapping and surveying of these existing utilities.

    Sonel LKZ-2000 system has a unique flexible operating modes to help you easily decide the right mode for your location application for the site conditions. The intelligent utility locator monitors the signal interference levels in all available modes and recommends which to use for the best results. Saving you time and giving you increased confidence in your results.

    Application for  Sonel LKZ-2000 - the best system for most challenging conditions!

    Sonel LKZ-2000 is designed to easily trace power cables over long and short distances with pinpoint accuracy, especially in areas with high levels of electrical interference. When used in conjunction with the supplied Multi Clamp a trace signal can be safely applied to an electrically live cable. The A-Frame accessory can also be used to easily locate cable sheath faults.

    The highly durable, weatherproof Sonel LKZ system has a flexible operating system to suit most site conditions and terrain, which is essential on complex and demanding civil engineering and construction sites.

    Damaging communication cables can be very costly and time consuming to repair, causing major disruption to the rail network. Sonel LKZ system is designed to easily locate and trace cables in congested areas and with high levels of electrical interference.

    Tracing and locating large bundled cables, such as fibre optic cables, can be difficult and time consuming. Sonel LKZ systems high frequency modes are ideally suited for these types odd cables, helping to improve your productivity and locating reliability of all cable types. The A-Frame accessory can be used to easily locate cable sheath faults.

    These can be the most potentially hazardous, costly or environmentally sensitive pipes to strike and therefore most important not to damage. Using the Sonel LKZ system’s range of low frequency modes, locating and tracing these pipes is easy over long distances, maintaining maximum accuracy.

    Locating and tracing pipes can support the mapping and surveying of utilities. Using the Sonel LKZ system with our dual frequency sonde is the ideal solution for locating deep underground non-metallic sewerage and drainage pipes, that can’t be detected using standard locating technology.

    Rapidox SF6 6100 Portable Gas Analyser

    Portable SF6 analysers Rapidox 6100 Overview

    The Rapidox SF6 6100 Portable is designed to test the quality of SF6 in MV & HV gas insulated electrical equipment. The analyser is pre-programmed with all current IEC and CIGRE test configurations, with the ability to create customised test parameters. Exceptional accuracy and stability are provided when measuring the purity of SF6 gas, through specially selected sensors. A output nozzle allows for the analyser to be attached to the Rapidox Gas Recovery Bag, ensuring that all sampled SF6 gas is recovered.

    For the power transmission and distribution network, SF6 technology remains essential. To protect personnel, equipment and the environment regular SF6 analysis should be adopted within the maintenance schedule. The early identification of any decomposition products and moisture within the SF6 gas will help avoid unnecessary shutdowns, outages and failures, in addition to reducing maintenance expenditures.

    The modular configuration allows for up to eight compatible gases to be analysed simultaneously with one analyser.  Internal SF6 gas pressure is recorded and logged by the analyser. All measured gases are analysed and data-logged simultaneously with only a few minutes required to achieve a stable reading. In order to accelerate the time taken in-between dew point readings, a unique Rapidri system is fitted to analysers measuring H2O. When not in use the sensor can be isolated via the ‘Run – Storage’ valve.

    Other measurable gases include H2O (dew point), SO2, HF, O2 & CF4. Due to the instruments modular design, a number of configurations are available in order to suit a variety of application requirements.
