Testo Instruments Deliver Instant Climate Data

The Testo 622 and Testo 623 temperature and humidity measuring instruments are claimed to provide a fast overview of humidity, temperature and pressure. The instruments are designed to deliver ambient climate data, time and date instantaneously. The Testo 623 temperature and humidity measuring instrument features a history function, and can undertake thorough analysis of crucial time periods.

The instrument is said to be ideal for facilities and estates managers, museums, officers and warehouses. The Testo 623 shows current and past measurement values in a large, easy-to-read display. The user can view either the humidity or the temperature values of past days in the histogram, displaying the measurement values for the past hour, two hours, 12 hours, 24 hours or 12 days. In total, the Testo 623 stores the data from the past 12 weeks.

In addition to temperature and humidity, the Testo 622 also measures pressure, and is of particular interest for applications in laboratories. Its large and easy-to-read display shows the current measurement values as well as date and time. Testo said it provides all important values for protocols at a glance. A reminder function informs the user when the next calibration is due. Using optional calibration and adjustment software from Testo, the user can carry out the calibration and the adjustment directly on site.

Vaisala Measurement Instruments Are DNV Approved

Vaisala has received a formal approval certificate from Det Norske Veritas (DNV) to guarantee that the company's measurement instruments will withstand harsh marine conditions. The certificate applies to a complete line of Vaisala's humidity, dewpoint, moisture in oil and barometric pressure transmitters serving measurement needs in applications from ship machinery rooms to bridges.

Improving a ship's onboard machinery performance is an ongoing challenge for ship builders and shipping companies. Precise, detailed and continuous online information can help solve the challenge by minimising maintenance costs and machinery downtime - while maximising system performance and energy efficiency.

'Vaisala offers high precision and stable measurement instruments to help optimise demanding industrial processes,' said Pekka Ravila, director of Vaisala's Targeted Industrial Applications segment. 'With the DNV certificate, we can now offer our shipping industry customers a complete set of certified instruments,' he added.

Emerson Has Chambers For Control Instruments

Emerson Process Management has a range of high-quality chambers that allows external mounting of level measurement and control instrumentation on process vessels. The 9901 chamber range, which has been adapted and extended from the existing range of Mobrey chambers, offers a standardised fully PED (Piping Equipment Directive) compliant design in accordance with ASME B31.3, allowing customers to buy an integrated bolt-on instrument solution from Emerson, or simply a chamber for use with existing instrumentation.

External mounting of level instrumentation is often preferred by users as it allows easy isolation of the instrument for routine maintenance or calibration, plus offers the additional benefit of acting as a stilling chamber for liquid surfaces prone to turbulence or fitting of instrumentation to vessels with internal structures such as tube bundles

Using only certified and traceable materials, the 9901 series is manufactured using full penetration welds, with welders and welding procedures qualified to both ASME and European standards. All chambers are hydro tested on completion, with a full range of NDT or customer inspection options available to order.

While the standard range is extensive and offers a cost-effective solution, a custom design and build service is available for instances where the chamber must fit existing vessels or replace old products. Standard chambers are available in carbon steel or stainless steel in sizes of 80mm or 100mm diameters with centres of up to 6m. A wide choice of process, drain and vent connections is offered to minimise fitting costs. Other materials, including exotic alloys, are available on request.
