The Aqua Troll 500 provides wireless access to
multi-parameter water quality measurement.
Water quality monitoring, whether for environmental studies, research or regulatory compliance is an operation that can benefit from instruments that automate or otherwise increase the efficiency of sample collection, measurement and data storage.

In-Situ Inc., manufacturer of reliable, top quality water monitoring equipment, adds to their already comprehensive line of portable and fixed installation water quality measurement instruments with the Aqua Troll 500. The instrument is a multiparameter sonde that can be used as a handheld device, with data transmitted to a smartphone running the Android data collection app. For fixed installations, the Aqua Troll can be integrated wirelessly into a telemetry system to deliver collected data to remote stations.

Some applications include:
  • Surface water spot sampling and profiling
  • Remote monitoring via telemetry
  • Long-term drinking water, wastewater or stormwater monitoring
  • Aquaculture
  • Low-flow groundwater sampling and remediation
Numerous features of the instrument are incorporated to decrease the amount of time required by technicians to put the instrument into operation and maintain it. The datasheet included below provides additional detail. Share your water quality measurement requirements and challenges with instrumentation experts.

Determining the proper location layout for hazardous gas
detectors is key to ensuring an acceptable level of safety.
MSA is committed to supporting operators of industrial facilities in their efforts to promote safe work environments that benefit employees, contractors and the community. Devices and instruments for flame and hazardous gas detection and monitoring are a part of the MSA family of safety products.

The ability to detect the presence and level of gases that may be hazardous is incorporated in physical devices and their function is well understood. The challenge faced by plant and facility operators is determining the locations for sensing devices throughout the facility that will provide an effective level of protection. MSA has a flame and gas mapping solution that employs quantitative models and actual facility conditions to provide a high level of confidence that overall target performance for flame and gas detection is achieved.

Refrigerant Leakage Monitor for Multiple Refrigerants



Monitoring HVAC machinery spaces for the presence of leaked refrigerant is driven by compliance, economic and safety concerns. Refrigerant gas can displace oxygen and lead to unbreathable atmosphere in enclosed spaces. On the economic front, refrigerant is expensive, and leakage must be replaced. Additionally, slowly leaking refrigerant will eventually result in system charge levels that negatively impact system operation and performance.

The MSA Chillgard 5000 monitors the levels of up to six selected refrigerants, providing alerts in the machine space, as well as an external alarm and activation of mechanical ventilation. The sensing technology can detect levels as low as 1 ppm, providing earliest possible warning of an alert condition.

The short video demonstrates the features of the unit that deliver reliability, versatility, stability and ease of operation and maintenance.

Monitoring Stormwater Runoff

Rain rinses the local area surfaces, cleaning them and concentrating all the soils, chemicals, and other loosened substances in stormwater runoff. The chemical composition of stormwater runoff can be complex, depending upon the activities conducted in the collection area. Stormwater runoff ultimately ends up in surface waters, rivers, lakes, streams, swamps, bays and oceans.

Stormwater runoff has been identified as a major contributor to surface water pollution. The current regulatory climate makes increasing demands on a number of local, municipal and private entities to monitor and analyze stormwater runoff to gather data that supports pollution control efforts and environmental studies.

Configuring an active stormwater collection and measurement system can be challenging. Teledyne ISCO, experts in environmental monitoring, crafted an application note that summarizes the hardware requirements for a typical system to be placed in the field. The app not is included below, but best results for a particular application or system will be achieved by sharing your environmental monitoring challenges with instrumentation specialists.
