3 Reasons to Rent Water Monitoring Equipment from the Manufacturer

Editor’s note: This article originally appeared on the In-Situ blog in May 2015. There are several reasons you might consider renting environmental sampling equipment: maybe it just makes more sense to rent equipment for a project rather than buy it, or perhaps you want to try the product before you make the commitment. Whatever the…

5 Ways to Improve Groundwater Sampling and Testing at Fracking Sites

Originally providing instrumentation for in-situ uranium mining, In-Situ®Inc. understands groundwater—-from groundwater sampling to aquifer testing. If you are looking for proven methods and reliable equipment to meet regulations for hydraulic fracturing we recommend partnering with a company, like In-Situ®Inc. that’s been working with mining professionals since 1976. In-Situ has shared with us 5 ways to improve groundwater sampling…

Not all pH Electrodes are the Same

If there is one thing our industry has no shortage of, its pH electrodes. There are several manufacturers all pushing their electrode as ‘compatible’; no matter which meter you happen to be using. While ‘compatible’ might hold true, electrodes are not as homogenous as some might lead you to believe. Across the breadth of pH…

The New In-Situ smarTroll RDO Handheld

How about a dedicated dissolved oxygen probe that you can use with your smartphone? The new smarTROLL RDO Handheld uses In-Situ’s robust optical RDO sensor which is one of the few on the market today with EPA approval for DO, BOD, and CBOD measurement.

Water Quality Monitoring….There’s An App For That!

In-Situ, Inc. has announced the release of the new SmarTROLL Multiparameter Probe with smartphone app. The SmarTROLL multiprobe system measures pH/ORP, conductivity, DO (optical), water level, salinity, TDS, resistivity, density, as well as air temperature and barometric pressure. The SmarTROLL multiprobe connects via cable to a battery pack with Bluetooth communications and up to 80…

Thermo Scientific Factory Authorized Service Provider

We are proud to announce that C.C. Lynch is now a factory authorized service provider for Thermo Scientific Water Analysis Instruments On-Line Analyzers in Texas, Louisiana, Mississippi, and Alabama.

Tech Tips from In-Situ, Inc.’s Tech Support

Tech Tip #1 RuggedReader Handheld PC acting slow or not responding? Think of it as a small computer that sometimes runs into errors. One way to keep it running better is to reboot it regularly like you do your PC. To do this, hold down the Power button for a few seconds until the Power…

Water Quality Monitoring With Remote Data Access

The need for remote data access for water quality monitoring stations is on the rise. Not only is there a significant cost involved in sending personnel into the field but there are also safety concerns in working in, over, and near the water. In addition, staff shortages can result in “stretching” out the time between…

In-Situ, Inc. Product Instructional Videos

In-Situ, Inc. has posted on their YouTube site several instructional videos for their LevelTROLL and TROLL 9500 products. These videos include:

Real Time Water Quality Monitoring on Rivers

Long term water quality monitoring on rivers can be an arduous chore; and very expensive. The cost of sending teammates into the field continues to skyrocket, especially when it is over water; not to mention the inherent safety concerns. All this for what amounts to a ‘snap-shot’ of water quality at the time of measurement…

In-Situ, Inc. Replaceable Battery Pack for LevelTROLL/AquaTROLL Instruments

In-Situ, Inc. has released the TROLL Replaceable Battery Pack compatible with all AquaTROLL 100/200 and LevelTROLL 300/500/700 instruments.

Aquatic Sensor Workgroup Guidance Documents

The Aquatic Sensor Workgroup is a public-private partnership of water-quality monitoring agencies, industry, and academia whose mission is to ensure that water-quality data collected by sensors are of known and documented quality. They have published several guidance documents that benefit anyone using or preparing to use water quality monitoring sensors for surface water or groundwater monitoring applications.

In-Situ, Inc. Extra Large Desiccant for TROLL Instruments

In-Situ, Inc. released an Extra Large Desiccant for their LevelTROLL 500/700, AquaTROLL 200, and TROLL 9500 instruments. Properly maintaining the desiccant on a vented pressure transducer is essential to its operation. A vented pressure transducer must maintain an open pathway to the atmosphere from the backside of the strain gauge in order to cancel out the effects…

In-Situ, Inc. RDO Sensor Recieves EPA Approval for NPDES Permit Holders for DO, BOD, and CBOD

On May 18, 2012, three In-Situ RDO methods received nationwide U.S. Environmental Protection Agency (EPA) approval for optical dissolved oxygen measurement. The In-Situ RDO methods are included in the final Methods Update Rule (http://water.epa.gov/scitech/methods/cwa/update_index.cfm). National Pollution Discharge and Elimination System (NPDES) permit holders may begin monitoring with In-Situ RDO methods. These optical (luminescent) methods can…

Logging Rain Gauge

Teledyne Isco offers two options for a logging rain gauge. The Isco 676 Rain Logging System uses an Isco 674 rain gauge and a 4120 Flow logger (minus the submerged pressure transducer) be to record rain events. The second option, Isco 677 Rain Logging System, uses the same 674 rain gauge but the more advanced…

In-Situ, Releases LevelTROLL 700H Meeting USGS OSW Accuracy Specification

In-Situ, Inc. has released the LevelTROLL 700H which meets the United States Geological Survey’s Office of Surface Water Accuracy Specification required for river/stream stage-discharge measurements and/or reservoir monitoring. The LevelTROLL 700H has an accuracy spec of +/-0.01 foot or 0.2% of the effective stage which is defined as, “the height of the water surface above…

Is Your Instrument Dry??? The Importance of Desiccant Maintenance

It is summer time and hot and humid conditions are upon us. Now is a good time to check and make sure your instruments are equipped with the proper desiccant. For equipment with vented level sensors, the desiccant prevents moisture from getting into the vent tube that provides a reference to atmospheric pressure. Failure to…

In-Situ, Inc. Releases the New AquaTROLL 400

Configuring your instrument can be time-consuming, frustrating, and expensive. The compact Aqua TROLL 400 Instrument from In-Situ Inc., simplifies decision making by offering a standard suite of six sensors. Connect the Aqua TROLL 400 to existing equipment and start measuring 12 parameters:

Low Flow Groundwater Sampling Simplified

Low flow groundwater sampling has become the norm for collecting groundwater samples during preliminary groundwater investigations, long-term groundwater monitoring, and during remedial activities. By using low flow purging and sampling techniques groundwater samples can be collected from a monitoring well that are representative of the groundwater within the formation adjacent to the well screen without…
