TDSK1800 Conductivity Solution, 901.6ppm/1800uS, 1Qt by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.

57-1281RK-17 M2A Stand Alone Sensor / Transmitter, combustible/CO2, without detector & j-box, specify gas and range by RKI Instruments

The RKI M2A™ is a state-of-the-art transmitter that can operate as an independent, stand-alone monitor or as part of an integrated system. The M2A connects with an analog or digital signal to virtually any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons and OLED menus. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2A provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging.

The housing of the M2A does not need to be opened for zeroing or calibration, making it unnecessary to declassify the area for routine maintenance. It is designed so that a complete field calibration can be performed by one person. Sensor construction is rated Class I, Div. 1 Groups B, C, D for flammables, CO, H2S, O2, and CO2, and Class I, Div. 2 for all other toxics.

The transmitter provides a 4-20 mA output in addition to a Modbus digital output. It also has two levels of alarms with relays, plus a fail alarm with relay. A digital display of the gas concentration, as well as alarm and status lights, can be viewed through the front window.

The toxic sensors are electrochemical type plug-in sensors, which provide high specificity, fast response, and long life. The plug-in design allows quick replacement in the field with no tools required. Toxic sensors are designed for use in Class I, Div. 2 hazardous locations. Sensors available for NH3, SO2, PH3, AsH3, and HCN.

The M2A represents the latest leading edge technology in sensor / transmitters today.

Effective firefighting requires trusted breathing protection in the harshest environments. The Draeger PSS® 5000 provides the budget-conscious fire department with an ergonomically advanced SCBA. With a wide range of features – such as bi-lateral hose routing and cylinder Quick Connection – the PSS® 5000 meets the needs for today's complex fire grounds.

Proven technology combines comfort with performance

The Draeger PSS 5000 SCBA is designed to withstand the high wear and tear that firefighters face daily – while providing an enhanced level of comfort and functionality. Made of tough chloroprene rubber material and Aramid-blend webbing, the PSS 5000 harness is ideally suited for extended wear and frequent use.

The flexible harness connects to a lightweight, stable back plate, while the waist belt pivots to reduce pressure on the wearer.

Integrated systems reduce risk and increase versatility

To minimize the risk of damage or snagging, the Draeger Sentinel 7000 electronic system and air-supply hoses are integrated into the backplate. To further streamline and reduce snag hazards, the lung-demand valve (LDV) - and Draeger Sentinel hoses are routed over the shoulders. Conventional waist-mounted hoses can also be fitted to the carrying system, making the Draeger PSS 5000 one of the most versatile SCBA systems available.

Easy maintenance to lower cost of ownership

The following features keep Draeger PSS 5000 downtime and maintenance costs to a minimum:

• Innovative slide-and-lock mechanism for fast and easy harness assembly and disassembly
• Harness detaches from the backplate without the use of tools
• First stage reducer snap-fit connection allows pneumatics to be fitted or removed quickly and easily
• Hose clips push in and out to allow swift removal of hoses from the harness pads for cleaning
• Chemical-resistant harness and waist belt design prevent excessive water absorption and reduce cleaning and drying time
• Standard AA batteries, no manufacturer-required overhaul, and few replacement parts contribute to a lower total cost of ownership over the life of the SCBA

Draeger Sentinel 7000 Real-time monitoring

The Sentinel 7000 electronic monitoring system provides options to satisfy the needs of any fire department. Incorporating a centralized power supply and pressure sensor module within the backplate, the robust system combines maximum component protection with balanced weight distribution for reduced physical stress.
