18105254-ISCN T40 Rattler Disposable Single Gas Monitor, CO ISCN by Industrial Scientific

The T40 II Rattler single gas detectoris primarily used to keep personnelsafe by detecting the presence of hydrogen sulfide(H2S) or carbon monoxide (CO), in a serviceable, maintainable, compliance instrument. The T40 II Rattler is the easiest gas detector to service while still makingcompliance easy and costeffectivewith a confidence flash. The T40 II Rattler is robust and light, with an ingress protection of IP66/IP68 and is suitable for working in the most challenging, hazardous area environments. T40 II Rattler introduces an ultra-fast T90 response time that can detect gas hazards on the job, saving valuable time, to ensure worker safety. To meet the needs of longterm operation, the high-performance lithium battery can operate under extreme weather conditions continuously for 2 years from powering up with a 1-year shelf life.

The T40 II Rattler is fitted with two visual red alarm LEDs, in addition to an audible and a vibration alarm when the gas concentrations exceed the High, Low, TWA, or STEL alarm preset values.

• Robust, compact, and light
• Ultra-Fast sensor response
• Automatic Self-Test
• Data and Event Logging
• Configurable Low and High alarm settings
• Optional TWA and STEL Alarm
• Multiple sensor range options with high accuracy
• Replaceable battery with 2-years run-time
• One Year Shelf Life

2432509 Bacteria Tests: Hach Slime Forming Bacteria 9 pk by AquaPhoenix

BART biodetectors are excellent diagnostic tools to help identify the presence of process disruptors, such as bacteria creating slime layers and limiting disinfection.

The SLYM-BARTs can be used as a P/A test capable of indicating to some extent the possible population size and the types of slime-forming organisms present in the water sample. Slime-forming bacteria are able to produce copious amounts of slime without necessarily having to use any iron. Iron bacteria also produce slime, but usually it is thinner and involves the accumulation of various forms of iron.

Slime-forming bacteria generally produce the thickest slime formations under aerobic (oxidative) conditions, which develop around the floating ball. Growth may be recognized as a cloudy or gel-like growth, which can be localized or occur throughout the sample. These growths are usually white, grey, yellow, or beige in color and can darken over time.

• Simple yet effective method for monitoring the population size and/or activity of specific groups of bacteria
• Easy to use, requiring no elaborate or costly equipment and no specialized training
• Effective and affordable tests are easy to interpret and can be performed at room temperature in virtually any environment

CAL-C110 pH & ORP Simulator by Sensorex

The C110 pH/mV checker simulator is a millivolt source that can be used to calibrate or check the calibration of a pH or ORP (mV) meter. It also serves as a troubleshooting toll when pH or ORP systems fail. For troubleshooting, the electrode is removed and the simulator is connected in its place. The C110 sends a signal to the meter to verify the performance of the meter. Signals of pH4, pH7 and pH10 are available, as well as +/-700mV for ORP. A properly working meter (by process of elimination) indicates that the electrode may be the cause of the failure.

Features:

• An essential tool for troubleshooting pH and ORP systems
• Compatible with most pH and ORP systems using BNC connectors
• Simulate high impedance loads
• Instantly ready for use and includes 9V battery
• One year limited warranty
