INSTRUMENT DETECTS GAS LEAKS IN VARIETY OF APPLICATIONS
Cameron Instruments has introduced the Variotec 460 Tracergas, developed for leak detection on underground pipes, gas and water distribution networks, pipelines in buildings, and heating systems. Detecting gas leaks by tracer gas involves feeding a mixture of 95% nitrogen (carrier gas) and 5% hydrogen into the system. The hydrogen escapes through the leak and is detected by the highly sensitive sensor. Tracer gas always looks for the shortest route from the leak to the surface, the company explains. The low amount of hydrogen means that the gas is incombustible as per ISO 10156, it adds. Measurements can be saved, and the results transmitted using the USB interface to a PC.

CLOSED-LOOP CONTROL ADVANCES HIGH LIQUID THROUGHPUT LABORATORY AUTOMATION
Festo has introduced the DHOP closed-loop pipette head for high-speed robotic pipetting applications delivers consistent volumes over a wide range of liquid viscosities. Liquid aspirates into the disposable tip using vacuum and dispenses using pressure to increase microfluidic speed and flexibility. By measuring the pressure change when a liquid is aspirated or dispensed, the device can calibrate for different viscosities without user input. Faster changeover between liquids leads to higher throughput and maximum device utilization, the company says. The pipette system integrates with Festo’s mechatronic systems, including the new EXCL multi-axis gantry (shown).

Endress+Hauser has introduced the Picomag, a pocket-sized device for measuring the flow of electrically conductive fluids, their process temperature and conductivity. The Picomag measurement device offers commissioning with Bluetooth using its free SmartBlue App, as well as system integration via an on-board IO-Link connectivity, making it Industry 4.0 ready, the company says. The device is suitable for cooling, warm or process water.
The XPR105MCP calibration balance from Mettler Toledo is said to be the high-speed solution for ISO 8655-compliant calibration of multichannel pipettes. It has a readability of 10 μg and supports multichannel pipettes with up to 12 channels and nominal volumes from 0.5 to 1000 μL. With a readability of 10 μg and repeatability of 15 μg, the system fulfills the requirements of ISO 8655 for multichannel pipettes with dispensing volumes as small as 0.5 μL. The weighing performance ensures accurate calibration, the company says, even at such small volumes. The results of a single dispense of up to 12 channels are calculated in under one minute. The unit tests each pipette channel individually on the same load cell to ensure equal measurement performance. The load cell is protected from any spills to ensure lifelong performance. The 360 measurements needed for a full calibration (12 channels, 3x10 repetitions) can be completed in as little as 25 minutes. The system can also be connected to a second calibration balance for increased throughput.
